MMFC Datasheet, PDF (1/2 Pages) OPLINK Communications Inc. – Fused Fiber Coupler

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.
