PM 780nm Polarization Maintaining Fiber Isolator

The PM780 Polarization Maintaining Fiber Isolator provides excellent optical isolation while maintaining polarization integrity in sensitive optical systems. Featuring low insertion loss, high return loss, and epoxy-free optical path design, this isolator ensures reliable performance with minimal polarization sensitivity.

Available in both single-stage and dual-stage configurations, the isolator offers isolation values up to 50dB and maintains precise polarization alignment through slow axis operation with fast axis cutoff. The compact package design makes it suitable for space-constrained applications.

Ideal for CATV fiber optic links, fiber amplifiers, optical test systems, LAN networks, and telecommunications, this isolator is offered with various fiber types, connector options, and cable lengths to meet diverse system integration requirements.
