Transmission method of optical fiber transmission subsystem

Abstract

The invention discloses a transmission method of an optical fiber transmission subsystem. The optical fiber transmission subsystem comprises an equipment machine frame, a plurality of service cards and a webmaster board. The service cards with different rates are managed by the webmaster board. The equipment machine frame is provided with N board slots, wherein one of slot positions is occupied by the webmaster board, and any one of the 1-N slot positions is selected by each service card. The transmission method comprises the following steps of: step 1, respectively receiving signals with different rates from different clients by the service cards with the different rates; step 2, realizing communication control of the service cards with the different rates with the clients with the corresponding rate under the condition that the service cards with the different rates are connected with a control bus. According to the transmission method disclosed by the invention, services with the different rates of 100 M, 1.25 G and 2.5 G are compatible with the subsystem simultaneously, and the service with a rate of 10 G can be further expanded. Therefore, the conventional equipment is used to the greatest extent, the entire cost is lower, the smooth transfer between a novel system and a traditional system is realized, and the transmission method has the advantages of flexible system configuration capability and logic control function.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a transmission platform, in particular to a transmission method of an optical fiber transmission subsystem. Background technique [0002] The common transmission platform in the existing computer room uses a 300pin optical module design, which has poor integration and high power consumption. Various rates and business functions are not compatible. Each additional function or rate requires multiple sets of equipment to be used together, which increases the cost and reduces the overall stability of the system. Moreover, adding a function or rate requires hardware updates and upgrades, consuming a lot of optical fiber and cable resources and rack resources in telecommunications equipment rooms. In the process of upgrading, it is necessary to change the original working method, replace hardware and software, cause business interruption, data loss may occur, and project implemen...
