Description
The KY-MU-SSB-15 series product is an optical CS-SSB modulation module developed by our company. The modulation module integrates Mach-Zehnder dual parallel modulators, bias point control circuits, 90 degree hybrid splitter, can achieve stable and reliable single sideband modulation, and can switch between left and right sideband control as needed. This product is mainly used in Brillouin fiber sensing systems, microwave photonics, gas detection and other fields.
