Product Detail
1. Low loss 2. High Extinction Ratio 3. High reliability

Polarization Maintaining Filter Coupler Module (1*3, 1*4, 1*8)

The PMFCM series is manufactured by using advanced technology to allow the input signal to be splitted into multi channels at a given splitting ratio with high extinction ratio, low excess loss, good uniformity, low wavelength dependance and low temperature dependance.  

Applications:

 1. Fiber Sensors;

 2. Amplifiers;

 3. Lasers.
