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. |
