A cross-connect board for realizing high-order cross-connect of synchronous digital system and its realization method

Abstract

The invention relates to a cross board for realizing synchronous digital hierarchy high-order cross and a realization method. The cross board comprises a power supply module, a clock module, a maintenance and management module, a business processing module, a control module, and a communication module, the power supply module supplies power for devices and monitors voltage and current states of each power supply, the communication module receives a cross command of a host computer, analyzes the command, and sends the command to the control module, the control module receives the cross command, determines whether the command is correct, and sends cross information to the business processing module for cross processing if correct, the clock module duplicates received clock frequency multiplication for 4 channels and provides required reference clocks, and the maintenance and management module obtains voltage and current information of a board, reports to the host computer if there is anomaly, switches off the power supply of the board, and reports information such as version information, cross ship temperature, and FPGA temperature of the board to the host computer. The beneficial effects of the cross board and the method are that the 640 G*640 G cross capacity and 40 G*20 G high-order cross are realized, the operation is simple, and the cross switching is accurate, timely, and stable.

Description

technical field [0001] The invention relates to an optical fiber communication crossover board, in particular to a crossover board for realizing high-order crossover of a synchronous digital system and a realization method thereof. technical background [0002] Due to the advantages of large transmission capacity, low loss, light weight, small size, strong anti-electromagnetic interference and good confidentiality, optical fiber communication has more and more applications in communication. Not only the backbone network and the metropolitan area network all use optical fiber transmission , and the access network generally uses optical fiber to achieve convergence. The problem brought about by this is that it is more and more difficult to conduct technical interception and reconnaissance on the vast amount of optical network information, especially when realizing crossover under the condition of large-capacity access, it is very difficult for hardware circuit design. challen...
