Polarization Maintaining Tap Isolator WDM Hybrid(PMTIW)
The Polarization Maintaining Tap Isolator WDM Hybrid is designed, which integrates functions of tap coupler, WDM and isolator. This device is characterized with low IL, high return loss, high extinction ratio and excellent environmental stability and reliability. They are ideal for polarization maintaining fiber amplifiers, fiber lasers, high speed communication system and instrumentation applications.
* High isolation
* Low insertion loss
* Excellent stability and reliability
* High power handling
* Fiber lasers
* Fiber amplifier
* Fiber Sensors
