Product Description

Description

The 850 nm Polarization Beam Combiner / Splitter is a micro-optic component designed to combine two orthogonal polarization signals into one single fiber, or, it can also be used to split orthogonal polarizations from a single input fiber (PM fiber or SM fiber) into two output PM fibers. It's widely used in EDFA or Raman Amplifier to enlarge pump power by combining two pump laser signals into a single ouput fiber. High Power handling is available upon request.
