Polarization Maintaining Tap Isolator(PMTAPI)

The Polarization Maintaining TAP Isolator is a hybrid device that has functions of tap coupler and isolator in a single compact package. The PMTAPI 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 application in fiber amplifier, and optical communication systems where signal monitoring is required.


Key Features:

* Low insertion loss

* High isolation

* High extinction ratio

* Excellent stability and reliability 


Applications:

* Fiber lasers

* Fiber amplifiers

* Optical Communications
