Product Detail
The PMFCM series is manufactured by using advanced technology to allow the input signal to be split into multiple channels at a given splitting ratio with high extinction ratio, low excess loss, good uniformity, low WDL and low TDL. It can be widely used in fiber sensors, amplifiers, various laser applications, etc.
