Polarization Maintaining Tap Coupler (PMTAP)

 

Description:

 

The polarization maintaining (PM) tap coupler is a compact low loss micro-optic filter type inline PM tap coupler (1x2) which provides a signal tap for monitoring over a wide bandwidth while preserving the transmitted polarization with high extinction ratio. It utilizes advanced filter technology to yield high extinction ratio, low insertion loss, wide bandwidth and high return loss in a compact package. The tap coupler can be provided with a wide range of tap ratios. It can also be provided with a PM isolator integrated in the same package.

 

 

Applications:

         EDFA
