Polarization Maintaining Filter Coupler Module( 2 x 4 / 4 x 4 )
|
The PMFCM series is manufactured using advanced
technology to allow the input signal to split into multi channels by a given
splitting ratio with high extinction ratio, low excess loss, low uniformity,
low WDL, low PDL and low TDL. It can be widely used in PM sensors, amplifiers,
lasers, etc..
