Description
The 2 μm Polarization Beam Combiner/Splitter is a compact high performance lightwave component that
polarization signals into one output fiber. The most common application is to combine the light of two pump
lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. The device can also be used
as a beam splitter.
