The Polarization Maintaining Optical Circulator is
a compact high performance light wave
component that routes incoming signals
from Port 1 to Port 2, and incoming Port
2 signals to Port 3. The component provides
high isolation, low insertion loss, high extinction
ratio, and excellent environment stability.
We developed the world smallest PM circulator
which the size is less than OD2.5 x 20mm, which
could be used in fiber sensing system along with
our other ultra mini size device. That could great
save your space for mounting.
