Description
The KY-CS-SSB-15-0118-FA is an optical CS-SSB modulation module developed by our company. The modulation module integrates Mach-Zehnder dual parallel modulators, bias point control circuits and broadband bridge, can achieve stable and reliable single sideband modulation, and can switch between left and right sideband control as needed. It can also be equipped with corresponding microwave sources to achieve wavelength scanning in multiple frequency ranges, and the wavelength scanning accuracy can reach 1KHz. This product is mainly used in Brillouin fiber sensing systems, microwave photonics, high-precision gas detection and other fields.
