Product introduction

The KY-MU-15-DPSK series DPSK optical modulation unit is an instrument developed by our company to realize 12.5Gbps DPSK optical signal modulation. The modulation unit can work in C+L band, and integrates low half-wave voltage electro-optic intensity modulator, high-saturation output electrical signal amplifier and corresponding bias point control circuit. The LED display area displays the bias point lock status in real time, which can make the modulation performance of the electro-optic intensity modulator no longer affected by external environmental temperature, vibration and other factors, and work stably for a long time.

This product is mainly used in scientific research, high-speed optical fiber communication systems and other fields. It can also be used as a standard optical signal generator for experiment or product testing.
