Free Space Isolator

Also referred to as Faraday isolators, free space isolators rely on the Faraday effect and are made with three components. That includes an input polarizer (vertical), output polarizer, and a Faraday rotator. This isolator blocks light from the opposite direction while allowing light from another direction.

VCHUNG offers isolators that suit TOSA/ROSA components. Our units utilize high-end magneto-optical crystals with high extinction and low absorption ratios as well as low loss. The peak isolation tops out at 45dB with a maximum aperture of 45mm and transmittance of ≥95%.
