Product Description
Polarization Maintaining Isolator PM Optical Isolator 1310 1480 1550nm High Isolation Low Insertion Loss For EDFA Fiber Laser Fiber Sensor And Optical Instrument
![]()
1. Product Overview
The Polarization Maintaining Isolator is a unidirectional optical transmission device designed for polarization-sensitive systems. 
2. Product Advantages
- Low Insertion Loss, Less Link Budget Pressure
- High Isolation, Effective Suppression of Backlight
- High Extinction Ratio, Selectable Slow-Axis or Dual-Axis Operation
Two polarization operating modes are provided:
- Type 1: Fast axis blocked, extinction ratio ≥20 / ≥18 dB, suitable for classic polarization-maintaining links that only require slow-axis operation;
- Type 2: Both axis working, extinction ratio ≥25 / ≥23 dB, suitable for special systems requiring dual polarization states.
- High Return Loss and Good Power Handling Capability
- Multi-wavelength coverage for unified platform design
- Clear performance estimates with connectors
