Three-Port Polarization Maintaining Fiber Circulator
The three-port polarization maintaining fiber circulator is a multi-port non-reciprocal optical device. It allows signals to transmit in one direction. When signals enter Port 1, they exit from Port 2, and signals entering Port 2 exit from Port 3. Similarly, signals entering Port 3 exit from Port 1. The device features low insertion loss and high isolation, making it suitable for various applications.
