Abstract: Aspects for data transmission over wired networks are described herein. The aspects may include a first transceiver and a second transceiver respectively connected to a communication bus. When the first transceiver receives differential signals from the communication bus, the first transceiver may be configured to convert the differential signals to digital signals and further to transmit the digital signals to a configurable logic circuit connected to both the first transceiver and the second transceiver. The configurable logic circuit may be configured to transmit the digital signals to the second transceiver when the communication bus is idle. The second transceiver may be configured to convert the digital signals back to differential signals and transmit the differential signals back to the communication bus.
