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.
