1064 nm 4-Port Polarization Maintaining Circulator

Overview

The FT-1064-27 is a four-port polarization maintaining circulator for 1064 nm optical systems. Light entering any port exits at the next port in sequence, enabling add-drop, bidirectional and interferometric architectures on PM fiber. Polarization is preserved through each path with a specified minimum extinction ratio, and high isolation between non-adjacent ports keeps crosstalk low. With low insertion loss plus high directivity and return loss, the device serves fiber optic instruments and PM fiber laser systems that need polarization-stable, direction-selective routing.
