Polarization
Maintaining Faraday Rotator (PMFR)
|
Description: The
Polarization Maintaining Faraday Rotator (PMFR) provides a 45°
rotation in either transmission direction. PM fibers on input and
output are aligned so that the output fiber major axis are at 45°
from the input. Therefore in one direction, transmission will be
maintained along the same axes (slow ®
slow or fast ®
fast). In the opposite direction, the axes will be switched. It
features low insertion loss, high extinction ratio, and high return
loss in a compact inline package. |
