Polarization Maintaining Beam
Combiner
PMBC Series
Product Description
Oplink’s Polarization Maintaining Beam Combiner (PMBC) is based on ather-
mal platform.The technology is a lead-free packaging platform and no epoxy
in the optical path.These devices feature super high extinction ratio, very high
power handling and low insertion loss.They are designed to work as pump
combiners for EDFA, Raman amplifier systems and 40-Gbps, 100-Gbps trans-
mission system. Oplink’s patented packaging technology ensures the highest
quality and reliability.
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 or subsystem.
