Mini Size 1×4 Fiber Optic Couplers
Optic Coupler Brief Introduces:
FBT Couplers(Splitter) utilizes precision technology to combine or
distribute light from single/multiple inputs to single/multiple
outputs bi-directionally. They are designed for power splitting and
tapping in telecommunication equipment, CATV network, and test
equipment.
1×4 FBT coupler is an optical splitter that uses the Fused Biconic
Taper (FBT) technique. The FBT technique is a well-known industry
technology for splitting optical power and/or splitting
wavelengths. The fused fiber coupler is created through a process
of fusing two bare fibers like an “X” and pulling the fused section
to achieve the desired optical characteristics. FBT couplers are
fused in tree structures to combine optical splitting effects to
create power ratio output of 1×N or 2×N, where “N” is the number of
desired outputs.
