PM 1950nm Polarization Maintaining Fiber Isolator
The PM 1950nm Polarization Maintaining Fiber Isolator delivers high-performance optical isolation with low insertion loss and excellent polarization stability. Operating at 1950±20 nm, this component provides reliable protection against back reflections while maintaining signal integrity through precise slow-axis operation and epoxy-free optical design.
Ideal for CATV fiber optic links, optical amplifiers, telecommunications, and LAN systems, the isolator ensures stable performance across extended temperature ranges. Available in both single-stage and dual-stage configurations with isolation up to 35 dB, its compact design supports flexible customization including multiple fiber types (PM1950/PM1550) and connector options for seamless integration into various optical systems.
