FBT Singlemode Tree/Star Coupler-blockness type

Fused Biconic Taper (FBT) coupler, also be called fiber splitter, based on the traditional technology, it is to bundle together 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 splitters 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

OMC’s Singlemode Tree/Star Coupler 1X4, 1X8, 1X16, 1X32 port ratios are available(or custom specified). They offer very low insertion loss, low polarization dependence, well controlled uniformity as well as excellent environmental stability. Standard tree coupler have been extensive used to split and mix optical signals in CATV, LANs and all other kinds of optical communication systems.
