Fiber optic coupler, is a device applicated in optical fiber systems with one or more input fibers and one or several output fibers.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.As a result of its great funciton,Optical splitter is a very important part in passive opitc networks (PON).FTB Fused fiber splitter (coupler) can do Singlemode (1310/1550nm) and Multimode (850nm).Cable diameter can be 0.9mm,2.0mm,3.0mm ,Single window,dual window and three window all we can supply .

Characteristics:

     Low insertion loss and excess loss
     Low polarization dependence
     High optical return loss
     Better uniformity
     Environmental Stability and Reliability
     Small package size

Application:

      FTTH, LAN, PON and Optical CATV
     Local ring net
     Optical fiber communication system
     Optical fiber test equipment
     Optical fiber sensor
