Optical backboard system and electric signal transmission method

Abstract

The invention relates to an optical backplane system and an electric signal transmission method. The optical backplane system comprises a plurality of data transmission modules; wherein each data transmission module comprises a modulation unit for converting and combining a plurality of groups of electric signals into a group of optical signals; the transmission unit is connected with the modulation unit and transmits the optical signal to the demodulation unit; and the demodulation unit is connected with the transmission unit and is used for receiving the optical signals and demodulating theoptical signals to obtain a plurality of groups of electric signals. According to the embodiment of the invention, electric signals are converted and combined into a group of optical signals; after the optical signals are transmitted through the transmission unit, the optical signals are demodulated to obtain initial electric signals, the number of optical channels needed by data transmission is reduced through modulation and final demodulation of the electric signals, and therefore the larger data transmission amount can be achieved through the original optical backplane without increasing the number of the optical channels of the optical backplane.

Description

technical field [0001] The invention relates to the technical field of optical backplane communication, in particular to an optical backplane system and an electrical signal transmission method. Background technique [0002] With the explosive growth of the transmission rate of the communication system, the copper interconnection has faced its development bottleneck, and the optical interconnection is the optimal solution to realize the high-speed interconnection of the Tbit / s level. The photoelectric board is made in the PCB, that is, the optical backplane. In optical backplane communication, each sub-board needs to be interconnected through optical channels in the optical backplane. [0003] Due to the large number of sub-boards, there are many optical channels in the optical backplane, which leads to the need for a large optical backplane or many layers to accommodate so many optical channels, which brings great difficulty to the production of optical backplanes.
