The Polarization Maintaining Isolator WDM is a hybrid device that has functions of WDM and isolator in a single compact package. The PMIWDM is characterized with low insertion loss, high extinction ratio, high isolation, high return loss and excellent environmental stability and reliability. It is ideal choice for fiber amplifier application to combine signal and pump wavelength with stable signal isolation.
Key Features:
* Low insertion loss
* High extinction ratio
* High isolation
* Excellent stability and reliability
Applications:
* Fiber lasers
* Fiber amplifiers
