Definition
A transceiver is a device comprising both a transmitter and a receiver which 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 word "transceiver" is a contraction of (radio) transmitter-receiver, so it is a device which contains both. A "walkie-talkie" is one example, a cell phone is another. The former is a simple device. You can either listen or talk.
Application
Transceivers can handle analog or digital signals, and in some cases, both. In regions where digital coverage is spotty, a transceiver may be equipped for analog to ensure that there will be no loss of signal. The ability to receive both can drive up the cost of the transceiver, due to the need to bundle in additional circuitry. Used in Very low power UHF wireless data transmitters and receivers , 315 / 433 / 868 and 915 MHz ISM/SRD band systems and RKE .
Transceiver module
A transceiver module is a group of transceivers comprising both a transmitter and a receiver which 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. Similar devices include transponders, transmitters, and repeaters.
Transceiver SFP
SFP transceivers are an interface with a motherboard, router, switch or optical media converter. Link connection into a fiber optic/ copper cable. Support SONNET, Fiber Channel, Gibe or similar standards. There are both multi-mode and single mode SFP transceiver types.
Conclusion
Transceiver (transmitter / receiver) modules offer a faster time-to-market alternative to chips/chipsets that allow designers at all levels of RF experience to integrate a completed wireless system into their products. Many modules are manufactured as a drop-in solution where designers create a compatible pin-out on their processor board and supply serial data to the appropriate pins.
