Center Wavelength(nm): 1310 or 1550 ORTE can provide optical circulator, like advanced circular optics for sensing, circular optical systems for LiDAR, circular optics for telecommunications, optical circular systems for autonomous vehicles, and other customizable circulars. ORTE's optical circulator has excellent key technical indicators: insertion loss (IL) as low as 0.8dB, isolation (ISO) as high as 40dB. These indicators ensure efficient and stable signal transmission, providing strong support for applications such as fiber optic sensors and optic instruments.
