Fiber optic splitter is an integrated wave guide optical power distribution device that can split an incident light beam into two or more light beams, and vice versa, containing multiple input and output ends. An optical splitter plays an important role in passive optical networks (suchas EPON, GPON, BPON, FTTX, FTTH, etc.) by allowing a single PON interface to be shared among many subscribers.
The passive optical splitter can split/separate an incident light beam into several light beams at a certain ratio. The 1x4 split configuration presented below is the basic structure: separating an incident light beam from a single input fiber cable into four light beams and transmitting them through four individual output fiber cables. For instance, if the input fiber optic cable carries 1000Mbps bandwidth, each user at the end of output fiber cables can use the networkwith 250 Mbps bandwidth.
FBT(Fused Biconical Taper) Splitters is the traditional technology in which two fibers are placed closely together, typically twisted around
each other and fused together by applying heat while the assembly is being elongated and tapered.
