Multimode Fiber Optic Coupler FBT ABS Module Type Low PDL
Fused Biconical Taper (FBT) Coupler is a kind of coupler fused by taper machine through fusing two or several pieces of optical fiber bundle. It has the advantages of small volume, high reliability, excellent uniformity.
FOC COMMUNICATION CO., LTD provides 1*N and 2*N fiber optic couplers. And these fiber optic couplers can be made as per customer request.
The mini size couplers are designed to meet the requirement of the optical modules and fiber systems which need the small coupler package size. FOC COMMUNICATION CO., LTD developed the mini size coupler with high stability and reliability. The smallest size of the coupler is φ3.0x30 mm.
