(November 2011) (Learn how and when to remove this template message) </Td> </Tr> <P> In computer networking, wire speed or wirespeed refers to the hypothetical peak physical layer net bitrate (useful information rate) of a cable (consisting of fiber - optical wires or copper wires) combined with a certain digital communication device, interface, or port . For example, the wire speed of Fast Ethernet is 100 Mbit / s also known as the peak bitrate, connection speed, useful bit rate, information rate, or digital bandwidth capacity . The wire speed is the data transfer rate that a telecommunications standard provides at a reference point between the physical layer and the datalink layer . </P> <P> The wire speed should not be confused with the line bitrate, also known as gross bit rate, raw bitrate or data signalling rate, which is 125 Mbit / s in fast Ethernet . In case there is a physical layer overhead, for example due to line coding or error - correcting codes, the line bitrate is higher than the wire speed . </P>
