1064 nm Polarization Maintaining Filter Coupler Module (1 × 4/1 × 8)

It can be widely used in fiber sensors, and amplifiers.
  • Product Detail

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 WDL and low TDL. It can be widely used in fiber sensors, amplifiers, lasers, etc.
