Isolators & Circulators
Fiber Optical Circulator 360-785nm
This Series Optical Circulators is a three-port device that allows light to travel in only one direction. A signal entering Port 1 will exit Port 2 with minimal loss, while a signal entering Port 2 will exit Port 3 with minimal loss. Light entering port 2 experiences a large amount of loss at port 1, and light entering port 3 experiences a large amount of loss at ports 2 and 1. Optical circulators are non-reciprocal devices. We uniquely offer high crosstalk between PM input signal at port 1 and reflection signal at port 3 up to 70dB, and high optical power of up to 10W, high polarization extinction ratio of up to 30dB. With our proprietary magnetic-optics technology and proven advanced micro-optics design, the circulator features low insertion loss, high isolation, high power handling, and high stability. Optical circulators are widely used in sensor and communication systems.

System integration
Integration and compatibility
Use these checks to connect Fiber Optical Circulator 360-785nm to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SM400, PM405, HI780, PM780, SM450, PM460, SM600, PM630, SM800, PM850, PM980 · Fiber Cover: 0.9mm
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Isolation: 20dB, 45dB, 65dB Lidar · Center Wavelength: 460nm, 405nm, 532nm, 785nm, 633nm, 660nm, 850nm, 980nm
- Check the Isolators & Circulators passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
