With the increasing consumption of information, the bandwidth needed for optical communication becomes larger and larger, and more and more energy is consumed. Today, with the increasing energy shortage, how to realize green communication has become one of the main directions of the industry.

In order to realize green communication, some new technologies are being or will be gradually adopted, such as new energy, high integration chip, high efficiency power module, intelligent fan, liquid refrigeration, intelligent flow aggregation, hardware dormancy, new materials and other technologies.

With the gradual introduction and continuous optimization of the above technologies, the energy consumption per bit of optical communication equipment will be gradually reduced and more harmonious with the environment.
