transceiver is a device comprising both a transmitter and a receiver that are combined and share common circuitry or a single housing. When no circuitry is common between transmit and receive functions, the device is a transmitter-receiver. The term originated in the early 1920s.

A transceiver is a combination transmitter/receiver in a single package. The term applies to wireless communications devices such as cellular telephones, cordless telephone sets, handheld two-way radios, and mobile two-way radios. Occasionally the term is used in reference to transmitter/receiver devices in cable or optical fiber systems.

In a radio transceiver, the receiver is silenced while transmitting. An electronic switch allows the transmitter and receiver to be connected to the same antenna, and prevents the transmitter output from damaging the receiver. With a transceiver of this kind, it is impossible to receive signals while transmitting. This mode is called half duplex. Transmission and reception often, but not always, are done on the same frequency.

Use these guidelines when you work with SFP and SFP+ modules: 

  • SFP and SFP+ modules are static sensitive. Wear an ESD-preventive wrist strap that is connected to the rack in order to prevent ESD damage.
  • SFP and SFP+ modules are dust sensitive. Always store the devices with dust plugs installed in the optical bores.
  • Do not remove and insert an SFP or SFP+ module more often than is necessary. Repeated removals and insertions of an SFP or SFP+ module can shorten its useful life.
