Description
The PM Filter Coupler (Polarization Maintaining Coupler) is a micro-optic filter type device that provides optical signal splitting while preserving polarization with high extinction ratio. It is available in a wide range of coupling ratios from 1% to 50%, and in 1×2 and 2×2 configurations.
PM couplers are widely used in fiber optic communication systems, Raman amplifiers, and other fiber instrument applications.
Key Features & Benefits
- Low Insertion Loss – Ensures efficient signal transmission.
- High Return Loss – Minimizes back reflection.
- High Extinction Ratio – Maintains polarization state reliably.
- Wide Coupling Ratio Range – Available from 1% to 50%.
- Flexible Configurations – 1×2 and 2×2 types available.
- Wide Applications – Fiber optic communication, Raman amplifiers, fiber instruments.
