Abstract: Aspects of a method and system for an extended range copper transceiver are provided. Reducing the communication rate provided by multi-rate physical (PHY) layer operations in an Ethernet transceiver may extend the range of the Ethernet transceiver over twisted-pair copper cabling from a standard connection length. The Ethernet transceiver may support up to 1 Gbps or up to 10 Gbps transmission rate over copper cabling. The multi-rate PHY layer architecture in the Ethernet transceiver may support signal-processing operations, such as echo cancellation and/or equalization, which may be applied to the reduced communication rate to enable range extension. The reduced communication rate may be achieved by reducing the symbol rate provided by the multi-rate PHY layer operations. Reducing the communication rate may also enable utilizing greater insertion loss cabling for a standard connection length.

Abstract: Disclosed are method and system for Ethernet media conversion supporting high-speed wireless access points. The method includes receiving at each of a plurality of input-side Ethernet modules in a media converter, a plurality of input data streams at a first data rate. In the media converter each of the plurality of input data streams may be aggregated into an output data stream at a second data rate. The output data stream may then be transmitted at the second data rate from an output-side Ethernet module in the media converter. Each of the input data streams may be received from an Ethernet switch, and the output data stream may be transmitted to a wireless access point. In one exemplary implementation, each of the input-side Ethernet modules may include a 1G PHY, while the output-side Ethernet module may include one or both of a 2.5G PHY and a 4G PHY.
