Product description
Conventional Wavelength Optical Circulator
In a three-port circulator, the optical signal input from Port 1 is only output from Port 2, the optical signal input from Port 2 is only output from Port 3, and the optical signal input from Port 3 is only output from Port 1. This product is widely used in fields such as fiber lasers, optical add-drop multiplexing, bidirectional pumping systems, dispersion compensation devices, fiber optic sensing, and scientific research. Zhongce Optoelectronics looks forward to cooperating with you.
