This device is a combination of a polarization independent optical isolator, and either a WDM filter or tap coupler. These devices are ideal for high power applications.
The AHC Series Integrated Component has extremely low polarization sensitivity, low insertion loss and high isolation for both WDM filter and isolators. Designed for compact and easy installation, it eliminates splices, requires less fiber routing and reduces losses when compared to discrete components.
Its high performance provides exceptionally stable signal isolation and wavelength division multiplexing over wide wavelength/temperature ranges and all polarization states. It is ideal for fiber amplifier and WDM network applications.
