Abstract

The invention relates to a photoelectric data transmission system and method implemented through a single network card. The system comprises an electrical port, an optical port, a central processing unit, a PHY chip, an internal memory and a flash memory, wherein the central processing unit is used for inquiring, generating a control code according to a medium insertion state value and a data transmission state value, sending the control code to the PHY chip, receiving and storing data packets sent by the electrical port or the optical port into the internal memory and storing the data packetsinto the flash memory when data transmission is abnormal; the PHY chip is used for receiving an electric signal and an optical signal, modifying the medium insertion state value and the data transmission state value according to the electric signal and the optical signal, and receiving the control code to achieve soft handoff communication with the electrical port or the optical port. By means ofthe system and method, resources are saved, the data packets of the optical port and the electrical port can be recognized in time, and the integrity of the transmitted data can be ensured.

Description

technical field [0001] The invention relates to the field of photoelectric data transmission, in particular to a photoelectric data transmission system and method realized by a single network card. Background technique [0002] Optical fiber transmission, that is, data and signal transmission using optical fiber as the medium. Optical fibers can not only be used to transmit analog and digital signals, but also meet the needs of video transmission. Optical fiber transmission is generally carried out using optical cables. The data transmission rate of a single optical fiber can reach several Gbps, and the transmission distance can reach tens of kilometers without using repeaters. Therefore, optical fiber transmission has the advantages of fast transmission speed and large amount of transmitted data, but it also has disadvantages such as high price and troublesome maintenance. [0003] Cable transmission transmits data electronically, which has the disadvantage of slow transm...
