3 Port Polarization Maintaining Optical Circulator 1310nm 1550nm
Description of 3-Port Polarization Maintaining PM Optical Circulator 1310nm 1550nm
The polarization maintaining optical circulator is a compact, high performance lightwave 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. They perform a similar function as an isolator, protecting the input fiber from return power, but also allowing the rejected light to be employed.
