Polarization Maintaining Beam
Combiner and Isolator Hybrid
PMIH Series
Product Description
Oplink’s polarization maintaining beam combiner and isolator hybrid deliv-
ers the combined functionality of a PMBC and an isolator within a single,
compact-sized package. Oplink’s integrated solution is designed to work as
pump combiner for EDFA and Raman amplifications and features very high
power handling and low insertion loss. Oplink’s patented packaging tech-
nology ensures the highest quality and reliability for robust operation.
Oplink can provide customized designs to meet specialized feature applica-
tions. Also, Oplink offers modular assemblies that integrate other compo-
nents to form a full function module or subsystem.
