1x2 Isolator Polarization Beam Combiner/Splitter (IPBC/IPBS)


1x2 Isolator Polarization Beam Combiner/Splitter(IPBC/S)combine the functionality of a PBC/S and an isolator into one component.Benefits of such devices includes reduction of component space and cost within assemblies and less splices.PBC/S can be used either as a polarization beam combiner to combine light beams from two PM input fibers into a single output fiber, or as a polarization beam splitter to split light from an input fiber into two output fibers of orthogonal polarization states.It is widely used in EDFA, raman amplifier, fiber sensor, coherent, telecommunications systems. Polarization mode dispersion compensator.
