Product introduction

The KY-OT-C-NRZ-40G series optical transmitter is an instrument developed by our company to realize 40Gbps NRZ optical signal output. It integrates C-band tunable laser light source, electro-optic intensity modulator, 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 in the linear region for a long time.

This product isolates the tunable laser source from the modulation part. It can be used as a tunable laser source and electro-optical modulation unit. It’s convenient and flexible. It’s mainly used in scientific research, high-speed optical fiber communication systems, microwave photonic links and other fields. It can also be used as a standard optical signal generator for experiment or product testing.
