PM 850nm Polarization Maintaining Fiber Isolator
The PM850 Polarization Maintaining Fiber Isolator delivers superior optical isolation while preserving polarization state integrity in demanding optical systems. Featuring low insertion loss, high return loss, and an epoxy-free optical path, this isolator ensures stable performance with minimal polarization-dependent loss.
Available in both single-stage and dual-stage configurations, the isolator provides isolation values up to 50dB and maintains precise polarization alignment through slow axis operation with fast axis cutoff. Its compact packaging is ideal for space-constrained installations.
Designed for CATV fiber optic links, optical amplifiers, test equipment, LAN systems, and telecommunications networks, this isolator is offered with various fiber types, connector options, and cable lengths to accommodate diverse system integration needs.
