4x4 FBT Optical Coupler(Splitter)
FBT Optical Coupler
Fiber optic splitter, also called optical splitter, fiber optic coupler, is a device applied in optical fiber systems with one or more input fibers and one or several output fibers. There are mainly two types of optical splitters. One is fused splitter (FTB),The other is Planar Lightwave Circuits (PLC Splitter).For the fused optical splitter, It can be divided into different ratios. such as 50/50 if the split is even, or 80/20 if 80% of the signal goes to one side and only 20% to the other. Planar Lightwave Circuits (PLC Splitter) can not work with different ratio rather than it provide a accurate splitting in high-density output (like 8,16,32,64 outputs). However, The most common type of fiber optic splitter splits the output evenly, which is coming out with the same output of light signals. As a result of its great function, Optical splitter is a very important part in passive optic networks (PON).
