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.
1× 2 Fiber Optic Coupler Features& Benefits:
1) Low insertion loss
2) Low PDL
3) Compact design
4) Good channel-to-channel uniformity
5) High directivity
6) High reliability and stability
7) Various coupling ratios are available
