PM Collimator

The PM Fiber Collimator is the basic element for in-line PM fiber optics components, such asPM isolator

 and PM DWDM. It has high extinction ratio, low insertion and high return loss. The unique processing

and high quality AR coating also enable this collimator to handle high power.

As general PM fiber & connector key are aligned to the slow axis.For devices with connectors, IL will be 0.3dB

higher, RL will be 5dB lower, and ER will be 2dB lower.
