PM1310 PM1550 1x2 PM Fiber Splitter Polarization Beam Splitter FC/UPC
The polarization-maintaining beam splitter can effectively couple 2 orthogonal polarization signal lights to a single fiber output, and can split a single polarization signal light into 2 orthogonal polarization signal lights when used in reverse. It is usually used for combining or splitting pump lasers into erbium-doped fiber amplifiers or Raman fiber amplifiers for power distribution. Both input and output use polarization maintaining fiber.
