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.

In order to meet the requirements of thousands of kilometers long-distance transmission in backbone network, coherent transmission technology is the mainstream transmission technology. But in the networking between cities, the transmission distance is usually less than 300 kilometers. In this case, how to avoid the use of coherent detection (complex system, high cost) to achieve good transmission and networking effect is a hot topic. In order to realize the medium and short distance transmission, the current main technologies mainly consider direct modulation and direct detection. There are many modulation methods, including pam-4, DMT, SSB, etc. On the receiving side, a noncoherent method is used, with fewer optoelectronic devices. In order to simplify the system and reduce the cost. In recent years, a number of direct debugging and direct inspection technology experiments have been carried out continuously. Through gradual research and continuous optimization, the pilot will start in the next three years. Inspection technology
