A Transceiver converts from one form of physical cable to another form. An example would be to convert the DB-15 of Thicknet to an RJ-45 for UTP. On some occasions, you will need a transceiver to extend a segment. Transceivers can combine one type of cable with a different type of adapter, as seen below, or they can be simple boxes with two different types of ports (for example, DB-15 and RJ-45), which plug into a machine’s Ethernet port, and allow the network’s standard cabling to be used to connect to a machine that doesn’t support that standard cabling. For example, many older workstations built before 10BaseT networks became popular, have an AUI connector for a Thicknet connection, as their only network adapter. To connect one of these machines to a modern 100BaseT network, you’d need to plug a 100BaseT-to-AUI transceiver into the machine’s AUI (Thicknet) port, and a 100BaseT cable into the RJ-45 port on the transceiver.
