1064nm Single Mode 3 Ports Optical Circulator

1064nm Single Mode 3 Ports Optical Circulator

The 1064nm Single Mode 3 Ports Optical Circulator is a passive, polarization-insensitive, nonreciprocal device designed to route light from Port 1 to Port 2 and from Port 2 to Port 3 while isolating the reverse optical paths. Centered at 1064 nm with an operating range of ±5 nm, it provides insertion loss of ≤2.2 dB, isolation of ≥22 dB, peak isolation of ≥28 dB, return loss of ≥50 dB, polarization-dependent loss of ≤0.15 dB, and crosstalk suppression of ≥45 dB for stable separation of forward- and backward-propagating signals.

Built with HI1060 single-mode fiber, the circulator is optimized for near-infrared fiber-optic systems operating around 1064 nm and supports a maximum CW optical power of 0.3 W. It is well suited for seed-laser and monitoring paths in fiber laser systems, FBG-based reflective systems, reflected-signal routing, fiber-optic sensing, precision optical measurement, and laboratory test applications. Pigtail length, fiber protection, and connector type can be configured to meet specific system and installation requirements.
