Problems solved by technology

Although this method can achieve hot backup, there are connections between the working unit, the backup unit and the daughter board at the same time, and these connections are realized through the high-speed data wiring on the backplane, and the high-speed data wiring on the backplane The slots of the working unit and the backup unit are still limited, and the capacity supported by the entire subrack is also limited
More importantly: this hot backup method increases the number of high-speed data lines on the backplane, which makes the backplane design more complicated and costs rise, and the aforementioned backplane design problems still exist

Embodiment Construction

[0034] The core of the present invention is to use the optical interface and the optical signal connection line to replace the electrical signal connector and the electrical signal wiring on the traditional backplane to complete the connection between the different daughter boards. The present invention will be further described below in conjunction with the drawings and embodiments.

[0035] image 3 A specific embodiment of the present invention, a schematic diagram of the realization of the hardware platform of the transmission device is given. in image 3 In addition to the processing part of the traditional service board, the sending daughter board 31 also includes an optical interface VSR311. The function of the optical interface VSR311 is to convert the high-speed data electrical signal that needs to be output into an optical signal, and it can also demultiplex the high-speed data as needed. The data signal becomes a sub-high-speed data signal, and then the processed optica...

Abstract

This invention provides a transmission equipment hardware platform which contains back board and sub-board wherein the sub-board has photo interface device for mutual conversion between electric signal and optic signal, said back board has optic signal connector in connection socket for connecting with sub-board and transmitting the optic signal between sub-board and back board. Said invention realizes one hardware platform supporting various equipments to expand equipment function and capacity.

Description

Technical field [0001] The present invention relates to the technical field of transmission in a communication system, in particular to a transmission equipment hardware platform. Background technique [0002] Common transmission equipment platform hardware is basically composed of two different parts, one of which is a single board that completes various functions (such as access, line transmission, cross-connection, official processing, control, power supply and protection, etc.) , Often called the daughter board; the other part is the single board that completes the signal connection between the daughter boards, often called the backplane (also called the mother board). The connection between these two parts is as follows figure 1 Shown. in figure 1 Among them, slot n (n≥1) is a connection slot set on the backplane, and there are signal connectors on the connection slots, which are used to connect to the daughter boards of various functions, and the backplane is connected to...
