PM Tree Coupler Module (1 × 4, 1 × 8)

Produts Details

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. It can be widely used in fiber sensors, amplifiers, lasers, etc
