0.0/5 rating (0 votes)

Description

the Polarization Maintaining Optical Circulator (fast axis blocked) is a compact lightwave component  that routes incoming signals from Port 1 to Port 2, incoming Port 2 signals to Port 3 and incoming Port 3 signals to Port 4, while blocking the reflected light. The component provides high isolation, low insertion loss, high extinction ratio, and excellent environment stability.
