Polarization Insensitive Optical Isolator
Multimode 1310nm, 1550nm
An optical isolator is a passive magneto-optic device that allows light to travel in only one direction. It consists of an input polarizer, a Faraday rotator with magnet, and an output polarizer. It guides optical light in one direction and eliminates back reflection and back scattering in the reverse direction at any polarization sate. It’s characterized Low Insertion Loss Optical Path Epoxy Free, high reliability and low Polarization Dependent Loss and low PMD. It has variety application of amplifiers, Fiber laser, LANs, and Fiber Optic Instruments etc.
