Abstract

The invention discloses a high-speed high-capacity photon transmission network and aims to provide a transmission network with a high integration degree and a stable time delay. The high-speed high-capacity photon transmission network is implemented by the following technical scheme: a random primary DBF (Digital Beam Forming) module is connected with each secondary DBF module; each secondary DBFmodule is connected with a final-stage DBF module; a symmetric data communication photon transmission network between the primary DBF modules and the secondary DBF modules, and between the secondary DBF modules and the final-stage DBF module is established; all optical fiber links are directly connected with a FPGA (Field Programmable Gate Array) high-speed GTH interface on each stage of DBF modules after photo/electricity and electricity/photo conversion, and a physical connection mode of the optical fiber link between each stage of modules is fixed; and the primary DBF modules receive or send digital signals to a plurality of secondary DBF modules, and the final-stage DBF module receives or sends digital signals of the plurality of secondary DBF modules so as to form a multi-stage bidirectional transmission network for transmitting the digital signals.

Description

technical field [0001] The invention belongs to the technical field of modularized comprehensive system integration, and specifically relates to a high-speed and large-capacity transmission network with a bandwidth exceeding 40 GHz in the optical communication transmission field between internal modules of the system. technical background [0002] With the rapid growth of global communication traffic and the diversification of business forms, high-speed integrated service networks have become the development trend of modern communication networks. The optical fiber of the future optical network has an extremely wide frequency band and can transmit huge information capacity. The future broadband network will have a throughput of Tb / s and an incoming rate of Gb / s. The highest network performance, the lowest transmission cost per bit and the most personalized network are the basic requirements that future networks will focus on. In a high-speed network, high-speed refers to hi...
