Polarization-Maintaining Optical Isolator Polarization Maintaining Products Adfiber
Single-pole - Operating wavelength: 1310, 1480, 1550 or Customized Single-pole - Typical isolation: 40 dB Single-pole - Minimum isolation: ≥30 dB
Polarization-maintaining devices preserve the original polarization state as far as possible, or transform it in a defined way, when joining or coupling polarized light between two polarization-maintaining fibers. Examples include PM connectors, PM collimators, PM multiplexers/demultiplexers, depolarizers/polarizers, polarization-dependent circulators and isolators, and polarization-maintaining optical couplers.
