Transceiver

Transceiver ( English portmanteau of transmitter and receiver; German transceiver ) is the name for a running in a constructive assembly combination of transmitter and receiver, originally in the ( analog ) radio technology, in their early days transmitter and receiver usually two often bulky devices were.

Generally accepted abbreviations for Rx Receiver / Receiver, Tx transmitter / transmitter and TRX ( rare TxRx or XCVR ) for the transceiver.

Use

Network adapter

In network adapters, the computer equipment, a transceiver as a rule is the one component which is ( more precisely, the feeding and decoupling of the signals to / from the medium ) is responsible for sending and receiving the signals via the transmission medium. Depending on which transmission medium is used, it involves electrical signals, light, or other electromagnetic waves.

The unit is also called the Medium Access Unit ( MAU). It forms on the side of the network medium ( cable) the interface for connecting network stations. MAU and AUI ( Attachment Unit Interface) today are usually accommodated on the network cards.

With the widespread at the beginning of the Ethernet network technology 10BASE5 coaxial cable ( " Yellow Cable ", " ThickNet ", " RG8 ") of the transceiver was a separate component that was pressed on the access point on the cable ( the contact to the inner and outer conductor is produced ) and then a (thanks to the interpretation of the signal electronics contained in the transceiver up to 50 m long ) AUI cable connection was to connect to the network adapter of a computer. This allowed, in spite of because of its thickness relatively rigid and therefore difficult to be laid " ThickNet " cable, a certain flexibility in selecting the installation site, whereas the thinner 10BASE2 ( ThinNet ) cable used to go straight to the ports on the computer was performed; In this technique, the transceiver in the network adapter was now integrated.

The addition to the ( more recent ) 10BASE2 and / or the 10BASE-T connection to continue existing AUI connector with the combo network adapters and small, compact transducer units for the connection of alternative transmission media such as fiber optic cable can be attached, etc., which also as are transceiver to call.

Computer networks

A transceiver may also be a computer system, over which passes data from one system to another. When a connection between a computer inventory management system and a data acquisition system is also called a transceiver. Here he depicts the processing and forwarding safe ( in both directions) of the information.

RFID

In the RFID transceiver come in the form of so-called " Reader" are used. These devices first send a signal to which the transponder (eg RFID tag) is sent a response, which then received by the transceiver and is forwarded to a (computer) system for further processing.
