1310nm Single Mode Polarization Insensitive Optical Isolator
The 1310nm Single Mode Polarization Insensitive Optical Isolator is a passive fiber optic device designed to ensure unidirectional light transmission and effectively suppress back reflections in optical systems. It operates at 1310 nm with a wide wavelength tolerance (±20 nm), making it well-suited for O-band communication and precision optical applications.
With a polarization insensitive design, the isolator maintains stable performance regardless of input polarization variations in standard single mode fiber systems. It provides reliable protection for laser sources while minimizing signal degradation through low insertion loss and high return loss.
Available in both single stage and dual stage configurations, this isolator supports flexible system design for applications requiring either low loss or enhanced isolation performance.
