1310nm Polarization Maintaining Optical Isolator
The 1310nm Polarization Maintaining Optical Isolator is a high-performance passive optical device designed to ensure unidirectional light transmission while preserving the input polarization state. Optimized for operation around 1310 nm, this isolator effectively suppresses back reflections and optical feedback, protecting sensitive components such as lasers and transmitters.
Constructed with polarization maintaining fiber (PM1300) and advanced magneto-optic technology, the device delivers high isolation up to 55 dB (dual-stage) with low insertion loss and stable polarization performance. The default slow-axis alignment ensures accurate polarization control, making it ideal for systems where signal stability and polarization integrity are critical.
Available in both single-stage and dual-stage configurations, this isolator provides flexible options for applications requiring enhanced isolation or improved system reliability.
