Polarization Maintaining Beam Combination
Oplink’s polarization maintaining beam combiner is perfect for next-generation
amplification systems that require multiple pump sources. These devices feature very
high power handling and low insertion loss due to the epoxy-free optical path. They
are designed to work as pump combiners for EDFA and Raman amplifier systems.
Oplink’s patented packaging technology ensures the highest quality and reliability.
Oplink can provide customized designs to meet specialized feature applications. Also,
Oplink offers modular assemblies that integrate other components to form a full
function module or subsystem.
