1x2 Polarization Beam Combiner(1310nm,1550nm,1064nm,980nm)
TAKFLY' Polarization-Maintaining Fiber-Based Polarization Beam Splitters are designed to split a single input into its orthogonal linear polarizations through two fiber outputs. The devices feature two legs of polarization-maintaining fiber on one side of a calcite prism and one leg of polarization-maintaining fiber on the other. These polarization beam splitters are frequently used in erbium-doped fiber amplifier or Raman amplifier.
