The invention relates to the technical field of optical communication, in particular to a high-speed ultra-long single-span single-core bidirectional transmission system, which comprises a forward transmission system and a reverse transmission system which share one optical cable and occupy one fiber core respectively, the receiving end of the forward transmission system is provided with a forwardremote pumping unit, and the receiving end of the reverse transmission system is provided with a reverse remote pumping unit; the bidirectional transmission system further comprises a first mixed remote gain unit and a second mixed remote gain unit which provide signal amplification functions for two directions at the same time, the forward remote pumping unit provides pumping light for the second mixed remote gain unit, and the reverse remote pumping unit provides pumping light for the first mixed remote gain unit. Only a single fiber core needs to be adopted in each transmission direction,a forward and reverse transmission system only needs to be provided with a remote pumping unit at the receiving end, the functions of four optical amplifiers can be achieved, and therefore ultra-long-distance optical transmission of high-speed services is achieved.
Description
【Technical field】 [0001] The invention relates to the technical field of optical communication, in particular to a high-speed ultra-long single-span single-core bidirectional transmission system. 【Background technique】 [0002] With the rapid development of emerging technologies and industries such as cloud computing and big data, telecom operators and Internet operations are under unprecedented pressure. With the increase in the number of connected devices, the amount of data generated will increase significantly, requiring higher bandwidth to meet, and the requirements for the network will further increase. In order to better meet these conditions, it is necessary to aggregate the computing and processing of these data to the cloud. During this process, the demand for data transmission will also increase greatly. From the perspective of communication development, high speed is the eternal theme of optical transmission network development. At present, 100G is the mainstrea...
