Network transceiver

Two transceivers

A network transceiver (also a transceiver from the English transceiver , from the words transmitter - transmitter and receiver - receiver) - a device for transmitting and receiving a signal between two physically different media of a communication system. This is a transmitter-receiver, a physical device that connects the joint of a computer (host computer) with a local network, such as Ethernet . Ethernet transceivers contain electronic devices that transmit signals from twisted pair cables to fiber optic cables and detect inconsistencies.

A transceiver allows a station to transmit and receive from a common network transmission medium. Additionally, Ethernet transceivers detect environmental inconsistencies and provide electrical isolation between stations. 10BASE2 and 10BASE5 transceivers are connected directly to the transmission medium (cable) common bus. Although the first usually uses an internal transceiver built into the controller and tee circuitry to connect to the cable, the second (10Base5) uses a separate external transceiver and AUI cable or transceiver cable to connect to the controller. 10BASE-F , 10BASE-T , FOIRL also commonly use internal transceivers. I must say that there are also external transceivers for 10Base2, 10BaseF, 10baseT and FOIRL, which can be separately connected to the AUI port either directly or via an AUI cable.

If the transceiver is the link between the optical and copper cables, then it is often called a media converter .
