Multi-Mode Single Window
Wideband Fiber Coupler
(1x2, 2x2)
MMFC Series
Product Description
Oplink’s single window, multi-mode wideband fiber couplers are highly stable
for multi-port optical signal splitting. They have very good uniformity, low ex-
cess loss and very low polarization sensitivity. All devices are tested accord-
ing to industry standard test procedures and are supplied with all pertinent
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.
