Brief principles and classification of PLC Splitter

图片
PLC splitter   or planar lightwave circuit splitter is a passive component that has the special waveguide made of planar silica, quartz or other materials. It is employed to split a strand of optical signal into two or more strands. PLC splitter also has lots of split ratios, and the most common ones are 1:8, 1:16, 1:32, 1:64, 2:8, 2:16, 2:32 and 2:64. Products usually accord with Telcordia GR-1209-CORE, Telcordia GR-1221-CORE.YD/T1117–2001 standards. There are many types of PLC splitters to meet with different needs in OLT and ONT connection and splitting of optical signals over   FTTH  passive optical networks. Importance of PLC Splitter PLC splitter is especially important in FTTH networks, which shares a single PON network with many subscribers. Having no electronics and power in PLC splitter, it is very cost-effective to provide reliable light distribution solutions. Unlike FBT (fused biconical taper) splitter, PLC splitter has a better performance that offers ...

Building Structure of Optical Line Terminal (OLT)

With increasingly advanced and matured technologies in telecommunication network, Fiber to the Home (FTTH) has drawn much more attention of companies specialized in telecommunication nowadays. Generally, the FTTH broadband connections consist of two types of systems, known as Active Optical Networks (AON) and Passive Optical Networks (PON). And most of FTTH deployments are inclined to use a PON due to its low cost and high performance that can help to save a certain amount of money on fiber costs. A Gigabit Passive Optical Network (GPON) system generally contains an optical line terminal (OLT) at the service provider’s central office. As one of the indispensable components of PON, optical line terminal thus plays an essential role in the performance of the whole network connection. What Is OLT? An  OLT  (optical line terminal), also known as optical line termination, acts as the endpoint hardware device in a passive optical network. The OLT contains a central processi...
