Fiber splitter , also named beam splitter, takes a single fiber optics signal and divides it into multiple signals. It is used to split one beam of optical fiber light into several parts at a certain ratio, for example, a 1X4 LC type equal splitting ratio fiber optic splitter can split the fiber optic light signal into four equal 25% parts and sent to the 4 different channels. Based on working wavelength difference there are single window and dual window  fiber optic splitters.  And there are single mode fiber splitter and multimode fiber splitters. Typical connectors installed on the fiber optic splitters are FC or SC type. Splitters contain no electronics and use no power. They are the network elements that put the passive in Passive Optical Network and are available in a variety of split ratios, including 1:8, 1:16, and 1:32. The most common type of fiber-optic splitter splits the output evenly, with half the signal going to one leg of the output and half going to...

Coarse wavelength division multiplexing (CWDM) technology is developed to expand the capacity of a fiber optic network without requiring additional fiber. In a CWDM system,  CWDM Mux/Demux  (multiplexer/demultiplexer) is the most important component. Usually, a CWDM Mux/Demux is used to increase the current fiber cable capacity by transmitting multiple wavelengths, typically up to 18 separate signals over one fiber. This article may mainly describe how to install your CWDM Mux/Demux system. Unless you are an experienced user, we recommend that you follow the detailed installation steps described in the rest of this article.   CWDM MUX/DEMUX Module Overview CWDM Mux/Demux module is a passive device, very reliable and simple to use. These devices are available with a variety of wavelength combinations, usually from 1270nm to 1610nm (20nm spacing). Based on different applications, a CWDM Mux/Demux module can be designed into different channels. A typical 4 channel Mux...

The structure of  Bulk fiber optical cables   has many important characteristics. The fiber cable construction needs to provide protection from outside environment during its installation and throught the fiber cable’s working life time. They must provide mechanical protection for all the fibers inside the cable, at the same time, the cable has to be pretty easy to handle. Most the time, non-netallic strength members are needed to fully take advantage of fiber’s dielectric property. Bulk fiber optical cables will experience tensile stress, abrasion, cutting, flexing, bending, crushing during the installation and its operation life. These mechanical stresses introduce macrobending, microbending, light signal loss attenuation. Because of manufacturing imperfectness, small surface defects often exist in the optical fibres. So in the real world, fibres tend to break at the cracks that begin from these surface defects under heavy tensile tension. Bulk Fiber Optic Cable ...

A converter, also called a transceiver, is a device comprises both atransmitter and a receiver which are combined and share common circuitry or a single housing. When no circuitry is common between transmit and receive functions, the device is a transmitter-receiver. The term originated in the early 1920s. Technically, transceivers must combine a significant amount of the transmitter and receiver handling circuitry . Fiber media converter , also known as fiber transceivers or Ethernet media converters, are simple networking devices that make it possible to connect two dissimilar media types such as twisted pair such as Cat 5 or Cat 6 cable with fiber optic cabling. To be plainer, they receive data signals, sent via one media, convert the signals and then transmit the signals into another. Fiber optic media converters can convert the signals sent from copper cable to signals that run on the fiber cable. They are copper to fiber or fiber-to-fiber conversion devices. They a...

As we know, fiber optic connector is an important fiber optic component used to link two fiber optic lines together. Beside connector, there is also another item, which is fiber optic adapter with panels to connecting multi fiber optic line. Specifically, the fiber optic adapter is a small device that used to terminate or link the fiber optic cables or fiber optic connectors between two fiber optic lines. In order to realize the fluent fiber optic connection, the fiber optic adapter panel shapes or types should be in accordance with the fiber optic connectors or cables. Common shapes of the adapters are square, rectangular, or round that with FC, LC, ST, SC, MTRJ types. There are also single mode and multimode fiber optic adapters or single mode and multimode fiber optic connections. So when purchasing fiber optic adapters for fiber connections, it is essential to choose the right fiber optic adapter according to the fiber optic connector or fiber optic cables. Standard or flange ...

The principles of best cable management for fiber patch cords are similar to those for copper patch cords. However, there are special considerations with optical fiber, and extra care is needed in some areas. 1. Planning Administration activities are initiated with a change request. The change request must contain all necessary information to begin the planning process. Searching the Records Once a request form is received, search the records to be sure of the circuit path. The floor plans provided by the system designer should show backbone/riser cables, TRs/FDs and lOs. Any changes or additions made since your cabling infrastructure was installed should also have been documented. If the records are stored in a database, a different screen can be displayed for each user. This screen should supply you with the information you need, including the riser and horizontal fiber pairs serving the particular WAO and the locations of available fiber. Check Design Guidelines and Mat...

by Fiber-MART.COM Fiber-Mart offers a wide range of end-to-end high performance copper and optical fiber solutions that include patch cords optimized to deliver guaranteed channel performance and applications support. The patch cords is critical to achieving optimal channel performance. However, patch cords have the potential to be the weakest link in copper and fiber network infrastructures. It is essential to follow correct procedures in administration of copper and fiber patch cords to achieve optimum performance and reliability. Applying best practice at every stage will also minimize costs related to moves, adds and changes. The best practice in managing patch cords can be divided into four parts—Planning, Preparation, Patching, and Validation. Note:  With some solutions, cross-connect wire (jumper wire) can be used for voice connections. This should be managed in the same careful manner as patch cords. Cable Management for Copper Patch Cords 1. Planning The Ch...

It is one of the greatest invention in optical communication. Erbium-doped optical fiber is incorporated a small amount of a rare earth element erbium (Er) ion. It is the core of the EDFA. From the late 1980s, the EDFA research has been making a major breakthrough continuously. As WDM technology greatly increases the capacity of optical communication, it becomes the most widely used optical amplifier device in the optical fiber communication. Principle EDFA is constituted by a period of erbium-doped fiber (about 10-30m) and pump light source. The stimulated emission of erbium-doped fiber under the action of the pump light source (wavelength 980nm or 1480nm), and the radiati...

As Fiber to the Home (FTTH) becomes more and more common, the term of fiber optic cable is no longer a strange noun for us. Let review it, a fiber optic cable is a most popular type of network cables that contains strands of glass fibers inside an insulated casing, which is in fact a assembly of optical fibers, the strength members and the cable jacket. Compare with the copper cables,  fiber optic cables  carry the communication signals by pulses of light rather than the electric. Due to the high capacity and less susceptible to electrical interference, fiber cables are widely used for the  fiber optic telecommunication networks . The optical fiber cables come in many different designs to fit for different environment and application areas. Choosing the right designed fiber cables is essential for your networking jobs. Loose Tube and Tight Buffer Cables Loose tuber and tight buffer are two typical designs of the fiber optic cables.  Loose tuber fiber cables...
