Technical field

The present disclosure relates to the field of optical communications, and in particular to an optical fiber communication method, device and system, a transceiver device, and a transmitting and receiving equipment.

Background technique

Network traffic has been growing continuously for many years. The interface speed of routers has evolved from GE to 10GE to 100GE, which is widely used now, and will evolve to 400GE, 800GE and even 1.6TE in the future. Traditionally, we hope to achieve a wavelength carrying a large-granularity service on an optical transmission bearer network. For example, a method that is widely used now is that a 100Gbit/s optical wavelength carries a 100GE service, which can simplify network management. However, as the interface rate continues to increase, limited by the problems of the materials themselves, the bandwidth of optoelectronic devices cannot be very high. For example, ADC/DAC chips, there is currently no technical path to achieve a 230GSa/s sampling rate, and it is becoming increasingly difficult. Meet the implementation of "one service, one wavelength".
