Factory Multimode MM 62.5/125um 650nm 50/50 Coupler Fiber Optic
Splitter
Product Description
Fused Biconic Taper (FBT) coupler, also be called FBT splitter,
based on the traditional technology, it is to bundle to- gether two
or more optical fibers, and then pull the cone machine melt
stretching, and real-time monitoring the change of the ratio,
spectral ratio requirements after melt stretching, one side retain
a single fiber (the rest of the cut) as input, the other end is a
multi-channel output.
As one of the key components for GPON FTTx networks, optical
splitters can be placed in the Central Office or in one of the
distribution points (outdoor or indoor) because the FBT coupler are
highly stable for multiport optical signal splitting with low
insertion loss. FBT couplers are designed for power splitting and
tapping in telecommunication equipment, CATV network, and test
equipment.
