In the existing backplane (backplane) ethernet system, the data is transmitted in one direction by the PAM-2 method through two pairs of copper traces in the direction of 10.3125GHz baud rate, providing the effective bit rate of 10.3125Gbps. Crosstalk surface effect ISI, copper traces backplane Ethernet system can make the data transmission rate of data is usually caused by the reliable receiving dispersion characteristics of copper traces and the dielectric loss caused by variable frequency start sending and loss from nearby communication lines limited. The present invention relates to a system to mitigate losses in the above and other signals in order to obtain speeds of up to two times the conventional 10Gbps limit in a backplane Ethernet system.
