Abstract
High speed data communication standards such as IEEE 802.3ae (also known as XAUI) use four lanes to transmit data half duplex at 10 Gb/s. In order to achieve full duplex, eight lanes need to be used. By introducing echo cancellers into the system, a high speed transceiver can be built with full duplex capability on four lanes, thereby saving 50% of the lane requirements when compared to XAUI while still maintaining a low symbol rate.
