PCIE signal transmission method and apparatus

Abstract

The invention provides a PCIE signal transmission method, which refers to communication field, and can improve transmission efficiency, reliability, save design cost, and is suitable for long-distance transmission. The method comprises the steps of generating a PCIE electric signal to be transmitted to an opposite-end apparatus, wherein the opposite-end apparatus is an apparatus excludes from the PCIE electric signal generating apparatus; converting the generated PCIE electric signal into a PCIE optical signal; and transmitting the PCIE optical signal to the opposite-end apparatus. The invention also provides corresponding apparatus.

Description

technical field [0001] The present invention relates to the communication field, in particular to a PCIE (Peripheral Component Interconnect Express, high-speed peripheral component interconnection) signal transmission method and device. Background technique [0002] At present, most of the architectures of computers and storage products are extended based on the PCIE bus. Because the PCIE bus has weak anti-attenuation ability and short transmission distance, it is generally only suitable for the communication link inside the device. When different devices that are far apart need to communicate, it is necessary to convert the PCIE signal inside the device into other protocol signals (such as Gigabit Ethernet signals, etc.) Communication between external devices. [0003] Adopting this implementation method, since a protocol conversion chip must be used for protocol conversion during the communication process, problems such as reduced transmission efficiency and increased de...

AI Technical Summary

Problems solved by technology

[0003] Using this implementation method, since the protocol conversion chip must be used for protocol conversion in the communication process, it will bring problems such as reduced transmission efficiency and increased design cost.

However, if the PCIE signal is directly used for transmission, it cannot overcome the weak anti-attenuation ability of the PCIE signal and the short transmission distance.
