Polarization Maintaining Optical Circulator
|
(PMCIR Series)
Spec Review No. SR1157
The Polarization Maintaining Optical Circulator is a compact high performance lightwave component
that transmits the incoming signal from port 1 to port 2, while transmitting another incoming signal
from port 2 to port 3. The component provides high isolation, low insertion loss, high extinction ratio,
and excellent environment stability.
