Multi-Mode Single Window Wideband Fused Fiber Coupler (1x2, 2x2) MMFC Series Product Description Oplink’s multi-mode single window wideband fused fiber couplers are highly stable for multi-port optical signal splitting. They have very good uniformity, low excess loss and very low polarization sensitivity. All devices are tested ac- cording to industry standard test procedures and are supplied with all perti- nent measurement data. Oplink can provide customized designs to meet specialized feature applica- tions. Also, Oplink offers modular assemblies that integrate other components to form a full function module.
