1064nm Polarization Insensitive Three-Port Optical Circulator

Overview

The FT-1064-38 is a polarization-insensitive three-port optical circulator for 1064 nm systems. Light entering port one exits through port two, and light entering port two exits through port three, allowing transmit and receive legs to share one fiber path. Because the design does not track polarization state, it fits non-PM links where input polarization drifts. Minimum isolation reaches 40 dB at center wavelength, with 35 dB maintained over wavelength and temperature. Maximum PDL is 0.15 dB and minimum return loss is 50 dB. The device handles up to 300 mW and works from 0 to +70 °C in a compact in-line package.
