Introduction to Fiber Optic Splice Closure

Fiber optic splicing is important for fiber connections. Fiber Optic Splice Closure is a fiber management product typically used with outdoor fiber optical cables. It provides space and protection for the fiber optic cable splicing and joint. Fiber splice closure is used for aerial, strand-mount FTTH „tap“ locations where drop cables are spliced to distribution cables.

What is a fiber Optic Splice Closure?

In fact, except underground application, fiber optic splice closure is also used for aerial, strand-mount FTTH “tap” locations where drop cables are spliced to distribution cables. It is usally used with outdoor fiber optic cables which provides space for the outdoor fiber optic cables to be spliced together. The fiber optic splice closures and the fiber trays inside will protect the spliced fiber and the joint parts of the outdoor fiber cables.

Fiber optic splice enclosures are used to protect stripped fiber optic cable and fiber optic splices from the environment, and they are available for indoor as well as outdoor mounting.Outdoor fiber optic enclosures are usually weatherproof with watertight seals.In a typical wall-mounted splice enclosure, fiber optic cable is supported by cable ties, and the cable strenght member is securely fastened to the enclosure’s support. Metallic strenght members must be grounded securely.the cable jacket(sheath) stops at the splice enclosure’s cable ties. Optical fiber tubes, individual tight buffered fibers, or pigtails are supported by the tube brackets and continue to the splicing trays.

Key Features of Fiber Optic Splice Closures

Fiber splice closures are made from special industrial grade, high tension plastic with a reliable moisture barrier. They are also optimized to resist aging of the material due to factors in the natural environment such as ultraviolet light.

Generally the fiber optic splice closures are horizontal types and dome type (also called vertical type). Horizontal types are used more often than vertical type (dome type) closures.

Horizontal Types

Horizontal types splice closure look like a flat or cylindrical box which provide space and protection for fiber optic cable splicing and joint. They can be mounted aerial, buried, or for underground applications. Most horizontal fiber optic splice closure can fit hundreds of fiber connection. They are designed to be waterproof and dust proof. They can be used in temperature ranging from -40°C to 85°C, can accommodate 70 to 106 kpa pressure and the case are usually made of high tensile construction plastic.

Vertical Types

Vertical type of fiber optic splice closure looks like a dome. This is why they are also called dome type. They meed the same specification as the horizontal types. They are usually designed for buried applications.



Fiber-Mart supplies two types of fiber splice closures which are the horizontal (inline) type and the vertical (dome) type. Both are made of excellent engineering plastics to be waterproof and dust proof. And with various ports types, they can fit different fiber optic core numbers.Fiber splice tray, fiber distribution box and fiber optic enclosure are also offered in conjunction with the splice closures, promoting a safe and well-managed environment for fiber optic splices.

Understanding of FTTx Network

FTTx technology plays an important role in providing higher bandwidth for global network. And FTTx (fiber to the x) architecture is a typical example of substituting copper by fiber in high data rate traffic.According to the different termination places, the common FTTx architectures include FTTH, FTTB, FTTP, FTTC and FTTN. This article will introduce these architectures respectively.


What is FTTx Network?

FTTx, also called as fiber to the x, is a collective term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications.

Different FTTx Architectures

FTTP: fiber-to-the-premises, is a loosely used term, which can encompass both FTTH and FTTB or sometimes is used a particular fiber network that includes both homes and businesses. It depends on how the context is used and specific location of where the fiber terminates. FTTP can offer higher bandwidth than any other broadband services, so operators usually use this technology to provide triple-play services.

FTTH: as indicated by the name fiber-to-the-home, fiber from the central office reaches the boundary of the living space, such as a box on the outside wall of a home. Once at the subscriber’s living or working space, the signal may be conveyed throughout the space using any means, such as twisted pair, coaxial pair, wireless, power line communication, or optical fiber. Passive optical networks (PONs) and point-to-point Ethernet are architectures that deliver triple play services over FTTH networks directly from a operator’s central office.

FTTB (fiber to the building) — Fiber terminates at the boundary of the building. A fiber cable in FTTB installation goes to a point on a shared property and the other cabling provides the connection to single homes, offices or other spaces. FTTB applications often use active or passive optical networks to distribute signals over a shared fiber optic cable to individual households of offices.

FTTC( fiber-to-the curb or -cabinet), is a telecommunication system where fiber optic cables run directly to a platform near homes or any business environment and serves several customers. Each of these customers has a connection to this platform via coaxial cable or twisted pair. The term “curb” is an abstraction and just as easily means a pole-mounted device or communications closet or shed. Typically any system terminating fiber within 1000 ft (300 m) of the customer premises equipment would be described as FTTC. A perfect deployment example of FTTC is a DLC/NGDLC (digital loop carrier) which provides phone service.

FTTN (fiber to the node) — Fiber terminates in a street cabinet, which may be miles away from the customer premises, with the final connections being copper. One of the main benefits of FTTN is the ability to deliver data over more efficient fiber optic lines, rather than other fiber optic lines with greater speed restriction



The advent of FTTx network is of great significance for people around the world. As it has a higher speed, costs less, and carries more capacity than twisted pair conductor or coaxial cables. Fiber-Mart can provide customized service ,pls don’t hesitate to contact me at

Loose Tube Cables In Outdoor Applications

Fiber optic cables are constructed in two ways: Loose Tube and tight buffered.and Loose tube optical cable designs are optimized for outside plant applications and have demonstrated over 20 years of proven field performance.



Loose tube cables are designed for harsh environment conditions in the outdoors. They protect the Fiber core, cladding, and Coating by enclosing everything within fairly rigid protective sleeves or tubes. Many loose tube cables contain a water resistant Gel surrounding the fibers. The gel helps protect the fibers from moisture, making the cables ideal for high humidity environments, where water or condensation may otherwise be problematic. The gel filled tubes can expand or contract with temperature changes, as well. Despite the benefits, gel filled loose tube cables are not the right choice if the Cable needs to be submerged in water, or routed around multiple bends. Excess Strain may cause the fibers to emerge from the gel. Tight buffered cables are optimal for indoor applications. Being more robust than loose-tube cables, they are best suited for moderate length LAN or WAN connections, long indoor runs, direct burial, and for underwater use. Rather than using the gel Layer loose tube has, tight buffered cables have a two-layer coating. The first is plastic, and the other, waterproof acrylate. The Acrylate keeps moisture away from the cable. The Core is never exposed when bend or compressed underwater. Tight buffered cables may be easier to install, because there is no gel to clean up and it does not require a fan out kit for Splicing or termination.



. Usable for ducts, direct burial, aerial installation
. Long distance communication system
. Subscriber network system
. Local area network system


Waterblocking requirement

loose tube fiber optic cable is designed to provide maximum protection against water penetration and water migration by utilizing intrusion preventative measures in both the cable core and the buffer tubes. Water-blocking protection of the cable core is accomplished by surrounding it with a dry water-swellable tape and yarns, or with a gel, to stop the entry and migration of water should the cable’s outer jacket be breached. This protective measure is included primarily to maintain the mechanical integrity of the cable itself (e.g. prevent ice crush from within the cable, fungus growth, or corrosion of metallic cable members when present). The water-blocking protection, water-swellable yarn or gel, is placed in the buffer tubes with the optical fiber during manufacture of the cable.



The predominant users of outside plant cable continue to specify loose tube cables in outdoor environments. Loose tube cables must pass rigorous mechanical, environmental and optical tests in accordance with accepted Electronic Industries Association/Telecommunications Industry Association (EIA/TIA) fiber optic test procedures (FOTPs). Loose tube cables are specifically designed to perform in harsh outdoor environments with minimal performance degradation. a new standard, ICEA S-104-696, “Standard for Indoor – Outdoor Optical Fiber Cables” has been developed which addresses the need for an inter-building and intrabuilding cable. These cables can be loose tube or tight buffered for the ease of termination such as premises cable, but must offer the tensile strength, waterblocking protection, and UV protection of an outside plant cable. These inter-/intrabuilding cables are typically used for short runs to connect to another building(s) and some limited premises applications.



Optical cables are designed to protect the optical fibers from damage due to the rigors of installation and from the demands of the surrounding environment. Fiber-Mart provides a wide range of quality optical fiber cables with detailed specifications displayed for your convenient selecting. Per foot price of each fiber cable is flexible depending on the quantities of your order, making your cost of large order unexpected lower. Customers can also have the flexibility to custom the cable plant to best fit their needs. Only fiber cable that meets or exceeds industry standards is used to ensure quality products with best-in-class performance. Any question pls feel free to contact me at

Rack Mount Fiber Enclosures Applications

Fiber enclosure has various designs and applications. Basically, rack mount fiber enclosures can be used in the following three circumstances, which are depended on the accessories that are installed on the fiber enclosure. The following will take a slide-out 1RU rack mount fiber enclosure as example to illustrate the applications of the fiber enclosures in data center. Installed with splice trays, fiber adapter panels and MTP cassettes separately, fiber enclosure can provide cabling environment for different connections.

For Fiber Splicing Joints

For fiber splicing joints in fiber enclosures, splice tray and FAPs are needed. When installing four fiber adapter panels on the front panel and one or more splicing trays inside the enclosure drawer, this fiber enclosure can provide cable management and protection for splicing joints and connections.

For Patch Cord Connections

This kind of fiber enclosure usage is very common. Simply by installing two slack spools and four fiber patch panel on the fiber enclosure, it could make fiber patch cables management much easier. The following picture shows a breakout fiber patch cable installed in the fiber enclosure and being well organized by the spools.

 Fiber Optic Power Meter

Important specifications for fiber optic power meters include wavelength range, optical power range, power resolution and power accuracy. Some devices are rack-mounted or handheld. Today we will focus on fiber optic power meters.


What does Optical Power Meter (OPM)mean?

An optical power meter (OPM) is a device used measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power meters (can be photodiode sensors or thermopile laser sensors), light meters or lux meters.

An optical power meter (OPM) is a testing instrument used to accurately measure the power of fiber optic equipment or the power of an optical signal passed through the fiber cable. It also helps in determining the power loss incurred to the optical signal while passing through the optical media. An optical power meter is made up of a calibrated sensor that measures amplifier circuit and a display. The sensor normally consists of a silicon (Si), germanium (Ge) or indium gallium arsenide (InGaAs) based semiconductor. The display unit shows the measured optical power and the corresponding wavelength of the optical signal.


Explains Optical Power Meter (OPM)


OPM calibrates the wavelength and measures the power of an optical signal. Before testing, the required wavelength is set manually or automatically. Accurate calibration of the signal wavelength is necessary for accurate measurement of power level, otherwise the test may yield false reading.

Different sensor types used in OPMs have different characteristics. For example, Si sensors tend to become saturated at low power levels and can only be used in 850 nanometer bands, while Ge sensors saturate at high power levels, but perform poorly at low power.

To calculate the power loss, OPM is first connected directly to an optical transmission device through a fiber pigtail, and the signal power is measured. Then the measurements are taken through OPM at the remote end of the fiber cable. The difference between the two measurements displays the total optical loss the signal incurred while propagating through the cable. Adding up all the losses calculated at different sections yields the overall loss incurred to the signal.


Three types of equipment can be used to measure optical power loss:


  • Component equipment – Optical Power Meters (OPMs) and Stabilized Light Sources (SLSs) are packaged separately, but when used together they can provide a measurement of end-to-end optical attenuation over an optical path. Such component equipment can also be used for other measurements.
  • Integrated test set – When an SLS and OPM are packaged in one unit, it is called an integrated test set. Traditionally, an integrated test set is usually called an OLTS. GR-198, Generic Requirements for Hand-Held Stabilized Light Sources, Optical Power Meters, Reflectance Meters, and Optical Loss Test Sets, discusses OLTS equipment in depth.
  • An Optical Time Domain Reflectometer (OTDR) can be used to measure optical link loss if its markers are set at the terminus points for which the fiber loss is desired. However a single-direction measurement may not be accurate if there are multiple fibers in a link, since the back-scatter coefficient is variable between fibers. The accuracy of such a measurement can be increased if the measurement is made as a bidirectional average of the fiber. GR-196, Generic Requirements for Optical Time Domain Reflectometer (OTDR) Type Equipment, discusses OTDR equipment in depth.

Fiber collimator is an effective passive optical component used for laser beam collimating. and Fiber optic collimators come in many forms.

There are more things to consider  when it comes to purchasing collimators .



Introduction to Fiber Collimator

Fiber Optic Collimators are devices used to expand and collimate the output light at the fiber end, or to couple light beams between two fibers. They are a module that combine a fiber and a lens, and has a function that produces parallel beams. We offer a range of fixed and adjustable fiber optic collimation packages for collimating a laser beam from the end of an FC/APC, FC/PC, or SMA connectorized fiber while maintaining diffraction-limited performance at the design wavelength.  They are available with different wavelengths (850 nm, 980 nm, 1060 nm, 1310 nm, 1550 nm) or fiber options (SM fiber, MM fiber, PM fiber, and LMA fiber, etc).


A fiber collimator is a device that narrows a beam of particles or waves. It can either cause the directions of light to become more aligned in a specific direction, or cause the spatial cross section of the beam to become smaller. Usually, fiber collimator is required to naturally transform diverging lights from an optical fiber to a parallel beam of light. It consists a single-mode or multimode fiber pigtail and a collimating lens. Collimator can also be used to calibrate other optical devices to check if all elements are aligned on the optical axis.


  • Low Insertion Loss and Return Loss
  • Low Back Reflection
  • High Extinction Ratio
  • Low Insertion Loss
  • Wide Operating Wavelength and Temperature
  • Scientific design with serious processing art


  • Optical cable jumper or pigtail cable
  • Laser Beam Collimating
  • Optical cable jumper or pigtail cable
  • PM Isolator and PW WDM
  • Laser Beam Collimating

How Does It Work?

When placing the fiber end on the collimator lens, the light will be aligned to a parallel direction. Then through a slight adjustment of fiber end position, the working distance is obtained. The working distance of fiber collimator is related to the distance between fiber end and lens. According to the actual demands, we can determine the parameters of fiber collimator, such as distance between fiber end and lens, beam radius, accuracy, to achieve better performance.


Selecting the right type of fiber collimator is essential to the performance of network, you should consider your project requirements as important factors. Fiber-MART offer a range of fixed and adjustable fiber optic collimation packages for collimating a laser beam from the end of an FC/APC, FC/PC, or SMA connectorized fiber while maintaining diffraction-limited performance at the design wavelength.

Different fibers and different connectors fiber adapter panels to choose.such as MTRJ patch panel, SC fiber patch panel ST fiber patch panel, FC fiber patch panel, LC fiber patch panel,MTP/MPO Fiber Adapter Panels and Customized Rack-Mount Fiber Patch Panels. Currently ,MTP / MPO cabling system helps ease the migration to 40 / 100G networks,The next step we will have to do is to see if the specific fiber link we are using is working properly.


To finish the test, two technology are required. Required materials needed are a roll of tape and the electric torch. Each technician is stationed at each end of the fiber link, perhaps in two different telecom closets which is where the fibers are usually terminated. Each technician must identify the specific fiber’s connector end, which in most cases is connected to an adapter on the back plane of the Fibre Optic Patch Panel or termination box.the test include the fiber connector (called the ferrule) directly against the electric torch with the light on. it must unlink the fiber connector from the patch panel adapter so that the tip of the fiber can be directly applied to the electric torch’s lens. When unlink the connector and extracting it a short distance from the patch panel, with at least enough slack to reach the electric torch lens. There are two prevalent types of fiber connectors in use today. The ST or round connector disconnects by pushing the connector toward the adapter and turning the connector body counter clockwise ¼ turn and then pulling the connector away from the termination. The SC or square connector is a push-pull termination and can be removed by simply grasping the connector body and pulling it out. In no case should a technician use any hand tools such as pliers to remove the connectors; if you cannot get the connector free by using just your fingers you are not doing the disconnection correctly.


Superiority of MPO/MTP Assemblies

Actual practice proves that MPO/MTP components are superior to other assemblies in high density applications.No tools are required to install the cassette in the panel enclosure, and the push-pull connection offers an easier way to be locked or unlocked in patch panels. recommended MPO/MTP products for high density patching as below.


MTP/MPO Fiber Adapter Panel

How to choose the basic 40G QSFP + optical components ?

With high-speed development of the optical communication industry,why is the third-party 40G QSFP with good compatibility and high stability the perfect choice for customers?


40G LR4 QSFP+ Transceiver

Conforming to the 802.3ba (40GBASE-LR4) standard, the 40G LR4 QSFP+ transceiver together with the LC connector can support an optical link length up to 10 kilometers over single mode fiber. 40G LR4 QSFP+ transceivers offer 4 independent transmit and receive channels. And to realize the function of transmitting the 4-channel signals over the single mode fiber, this kind of transceiver has to introduce MUX/DEMUX to multiplex/de-multiplex optical signals.the working principle of this kind of QSFP+ transceiver is : In the transmit side, four 10 Gbp/s serial data streams are passed to laser drivers. The laser drivers control directly modulated lasers (DMLs) with wavelengths. the output of the four DMLs are optically multiplexed to a single-mode fiber through an industry-standard LC connector. In the receive side, the four 10 Gbp/s optical data streams are optically de-multiplexed by the integrated optical demultiplexer; then, each data steam is recovered by a PIN photodetector/transimpedance amplifier and passed to an output driver. The following figure shows the functional block diagram of the 40G LR4 QSFP+ transceiver.

40G SR4 QSFP+ Transceiver

40GBASE-SR4 QSFP+, Short-reach (SR) transceivers for 40G connectivity in a QSFP form factor, uses independent transmitter and receiver sections, each with 4 parallel fiber strands. It can transmit 150 meters over OM4 MMF. For a 40G connection, 8 fiber strands are required, and 12-fiber MPO connectors are used. Consequently, 4 fiber strands in each connection are wasted .For most data center networks, the aggregation-layer fiber infrastructure is built for 10G connectivity. That either supports direct connections between devices over LC-to-LC MMF, or uses LC-to-LC fibers to attach devices to patch panels. Regular duplex LC-to-LC fibers cannot be directly reused for 40G connectivity using traditional 40G transceivers.The operating principle of the 40G SR4 QSFP+ Transceiver is : the transmitter converts parallel electrical input signals into parallel optical signals through the use of a laser array. Then the parallel optical signals are transmitted parallelly through the multimode fiber ribbon. Reversely, the receiver converts parallel optical input signals via a photo detector array into parallel electrical output signals. The following figure shows the functional block diagram of the 40G SR4 QSFP+ Transceiver.

10G Modules —XENAKIS Modules, X2 optical module,10G XFP optical module,10G SFP+ optical module

10 gigabit Ethernet is a telecommunication technology that offers data speeds up to 10 billion bits per second. 10 gigabit Ethernet (10-Gigabit Ethernet) is also known as 10GE, 10GbE or 10 GigE.10G SFP+ transceivers are multi-purpose optical modules for 10Gbit/s data.


Module Types

XENPAK – the original 10GbE pluggable optics.  Presents SC connectors

X2 – the successor to the XENPAK.  Presents SC connectors

XFP – the first of the small form factor 10GbE optics.  Presents LC connectors

SFP+ – a 10GbE optics using the same physical form factor as a gigabit SFP.  Because of this, many of the small SFP+ based 10GbE switches use 1G/10G ports, giving an added degree of flexibility.  Presents LC connectors.


10G Modules–XENAKIS Modules

XENPAK became the new standard transceiver with increased support across longer distances and for multiple wavelengths. Unlike GBIC transceivers that sent information across either copper or fiber optic channels, XENPAKs included support for both networks, creating a better, more flexible module. And unlike the bigger GBIC transceivers, XENPAKs were capable of conveying data across short and long distances due to their configuration settings located inside the devices. When utilizing a single-mode configuration, networks create a single ray of light to send data across a long distance, while they use a multimode setup to transmit information across short distances. Both single and multimode fiber optics were utilized by networks, creating the XENPAK device ideal.

10G Modules—10G X2 optical module

X2 is a kind of optical transceiver module specified for 10-Gigabit Ethernet and 10G Fibre Channel applications.X2 defines a smaller form-factor 10 Gb/s pluggable fiber optic transceiver optimized for 802.3ae Ethernet,ANSI/ITUT OC192/STM- 64 SONET/SDH interfaces,ITUT G.709,OIF OC192 VSR,INCITS/ANSI 10GFC (10 Gigabit Fibre Channel) and other 10 Gigabit applications.X2 is initially centered on optical links to 10 kilometers and is ideally suited for Ethernet,Fibre Channel and telecom switches and standard PCI (peripheral component interconnect) based server and storage connections. X2 is physically smaller than XENPAK but maintains the mature electrical I/O specification based on the XENPAK MSA and continues to provide robust thermal performance and electromagnetic shielding. The 10GB X2 fiber optic transceivers series include X2-10GB-SR, X2-10GB-LR, X2-10GB-ER and X2-10GB-ZR, they are designed based on the X2 MSA and IEEE802.3ae. They’re created for the integrated systems solution provide, fiber optics distributor along with other IT distributors.

10G Modules—10G XFP optical module

XFP is a standard for the transceivers. This type of transceiver is not dependent on the protocol. Generally, it operates at optical wavelengths corresponding to 850nm, 1310nm or 1550nm. Principal applications include 10 Gigabit Ethernet, 10 Gbit/s Fibre Channel, synchronous optical networking (SONET) at OC-192 rates, synchronous optical networking STM-64, 10 Gbit/s Optical Transport Network (OTN) OTU-2, and parallel optics links. They can operate over a single wavelength or use dense wavelength-division multiplexing techniques. The modules belonging to the XFP are hot swappable which means that the function of replacing the computer system components can be performed without shutting down the system. They include digital diagnostics that provide management which were added to the SFF-8472 standard. XFP modules make use of an LC fiber connector type to achieve high density.

10G Modules10G SFP+ optical module

SFP+ can be referred to as an expansion of the SFP standard. It has the capability to support speeds of 10 Gbps or even higher over fiber. The SFP+ product family includes cages, connectors, and copper cable assemblies. It is also similar to the performance requirements of SFF-8431 and also supports 8G Fiber Channel and 10G Ethernet applications. SPF+ comes with various advantages. It is a more compact factor package than compared to that of XFP.

How to Use OADM in WDM Network ?

OADM is a cost-effective and easy to use passive fiber optic component, which can provide easy to build and grow connectivity environment for WDM network.Optical add-drop multiplexer is one of the key devices to implement such optical signal processing. Use of OADM makes it possible to freely add or drop signals with arbitrary wavelengths over multiplexed optical signals by assigning a wavelength to each destination.this article ,Let us introduce how to use OADM in WDM Network?

Inside an OADM

A traditional OADM consists of three parts: an optical demultiplexer, an optical multiplexer and between them a method of reconfiguring the paths between the optical demultiplexer, the optical multiplexer and a set of ports for adding and dropping signals. The multiplexer is used to couple two or more wavelengths into the same fiber. Then the reconfiguration can be achieved by a fiber patch panel or by optical switches which direct the wavelengths to the optical multiplexer or to drop ports. The demultiplexer undoes what the multiplexer has done. It separates a multiplicity of wavelengths in a fiber and directs them to many fibers.

Main Function and Principle of OADM

For an OADM, „Add“ refers to the capability of the device to add one or more new wavelength channels to an existing multi-wavelength WDM signal while „drop“ refers to drop or remove one or more channels, passing those signals to another network path. The OADM selectively removes (drops) a wavelength from a multiplicity of wavelengths in a fiber, and thus from traffic on the particular channel. It then adds in the same direction of data flow the same wavelength, but with different data content. The main function of OADM function is shown in the following picture. This function is especially used in WDM ring systems as well as in long-haul with drop-add features.

How to Connect OADM With WDM MUX/DEMUX

In most cases, OADM is deployed with CWDM or DWDM MUX/DEMUX. It is usually installed in a fiber optic link between two WDM MUX/DEMUXs. The following picture shows a CWDM network using a 1-channel dual fiber OADM between two CWDM MUX/DEMUXs. Signals over 1470 nm are required to be added to and dropped from the dual fiber link. On the OADM, there are usually one port for input and one port for output. The OADM can be regarded as a length of fiber cable in the fiber link. The point is the one or more strand of signals is added or dropped when the light goes through the OADM.


OADM is still evolving, and although these components are relatively small, they are immeasurable in the future.Optical Add-Drop Multiplexer (OADM) is used for multiplexing and routing different channels of fiber into or out of a single fiber. The CWDM OADM is designed to optically add/drop one or multiple CWDM channels into one or two fibers. Fiber-Mart provides a series of OADM modules which can be Customized. For more information, welcome to visit or contact me by e-mail:
