Product Description
Polarization Maintaining Fiber Optic PM Filter Coupler for ICT AI Computing
Product Overview
The Polarization Maintaining Coupler is a micro optic filter type device that provides optical signal splitting while preserving polarization with high extinction ratio. Available in a wide range of coupling ratios from 1% to 50%, and in both 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
- Low Insertion Loss
- High Return Loss
- High Extinction Ratio
