Product introduction

The KY-MU-SSB-15 series product is an optical carrier suppression single sideband modulation unit developed by our company. The modulation unit integrates Mach-Zehnder dual parallel modulators, bias point control circuits, RF drivers and wideband bridges, can achieve stable and reliable single sideband modulation, and can switch between left and right sideband control as needed. The front panel indicator shows the lock status of the bias point control circuit in real time. This product is mainly used in Brillouin fiber sensing systems, microwave photonics, gas detection and other fields.
