1550nm Polarization Insensitive Isolator WDM Hybrid IWDM For Optical Amplifier
The IWDM is built based on isolator and thin film filter to fullfill hybrid isolator+WDM function in one single compact package, it includes two different confugration due to pump direction, "forward pump" and "backward pump".
Features:
Wide Operating Wavelength
Low IL & PDL & High Isolation
High Stability and Reliability
Application:
Fiber Amplifier
Fiber optic Instrument
