Product Overview of PM Circulator
High Reliability & Stability 1310-2050nm Polarization Maintaining
Fiber Circulator for Fiber Sensor
Polarization Maintaining Circulator
GEZHI 1310-2050nm 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. So fiber optic circulators act as signal routers, transmitting
light from an input fiber to an output fiber, but directing light
that returns along that output fiber to a third port.
