Polarization Diversity Receiver Eliminates Polarization Fading in Fiber Optic Interferometers



RENTON, Wash., September 17, 2019 — Lightel’s Polarization Diversity Receiver Eliminates Polarization Fading in Fiber Optic Interferometers

Lightel’s Polarization Diversity Receiver (PDR) performs as a receiver for fiber optic interferometers that are susceptible to polarization fading because of random birefringence variations. The device incorporates three independent polarized PIN diodes ensuring that at least one output has high interferometric visibility. This approach eliminates polarization fading in fiber optic interferometers without a consequential lowering of the signal-to-noise ratio. Lightel’s PDR is available in 1550nm and 1310nm wavelengths, the unit is PCB mountable and is offered with 900micron tubing and a variety of connector options.
