BoxOptronics 1310nm 1550nm SM or MM fiber optic FBT couplers splitters have a flat spectral response across the entire specified range. They are available with a coupling ratio of 50:50, 80:20, 90:10, 99:1. the wideband (±40 nm bandwidth)couplers that can be used at 1310nm, 1550nm, C band or L band are featured below. These couplers can handle a max power of 300mW(CW) with connectors.
1X2 Polarization Beam Combiner Splitter is designed to either combine or split linearlypolarized light. When used as a combiner, the linearly polarized input lights are combined into a single output with two orthogonal linear polarizations. When used as a splitter, an input light with two orthogonal linear polarizations is split into two outputs each with a single linear polarization. These polarization beam combiners are frequently utilized to combine the light from two pump lasers into a single fiber to increase the power input to an erbium-doped fiber amplifier or Raman amplifier.
