1. Transceiver Modules
A transceiver module is a device that comprises of a transmitter and receiver which combine under
a common circuitry. This combination of the two into one device result in a unit that is self
contained and can transmit as well as receive. A transceiver plugs into a module socket and is a
hot-swappable input output device. The unit connects the electric circuit with the copper network
also known as the optical network.
There are some devices available that have more than one transceiver module slots like network
interface cards and routers. The transceiver module is then usually inserted into one of the slots
which can be GBIC, SFP or XFP according to the appropriate slot for the particular module. The
optical network fiber is then plugged into a connector located on the transceiver module. The
different types of transceiver modules come about as a result of the different types of fiber, wire,
the different wavelengths within a given fiber and the different communication distances. The
different types of transceiver modules also come in various form factors in fiber optics or metal
wiring designed and they all support different data speeds and rates.
The most common of the form factors in which transceivers come in are: GBIC short for Gigabit
Interface Converter, SFP which stands for Small Form-Factor Pluggable, SFP+, QSFP+ meaning
Quad Small Form-Factor Pluggable Plus, CFP short for C Form-Factor Pluggable and XENPAK,
XAUI, XFP and X2. These all have different Gigabit Ethernet which refers to the technology used
in the transmission process of Ethernet frames at a rate of a single gigabit in one second.
Transceiver modules are also used in radio technology for CB radios and walkie-talkies.
Originally, the transmitter and receiver were separate units of the radio until 1920 when they were
merged into one. This resulted in ham radio operators building their equipment. Today almost all
amateur or ham radio equipment is a transceiver. However, Shortwave Listening Operators are on
the look out for pure radio transceivers which have almost been phased out. Modems, mobile
telephones and wired telephones as well as other radiotelephones also use transceiver modules for
the purpose of communication. The entire unit is usually a transceiver. For a cordless telephone,
the handset uses a radio and audio transceiver while the base station uses a radio transceiver. If a
speakerphone is included in the cordless phone then the base will become an audio transceiver just
like the handset.
As transceivers are interchangeable and can be used with the different optical technologies that are
present in your home network, they make a good investment. This is because they help to increase
flexibility in case an expansion of the network is needed and also as they lower the initial costs of
creating the network. UTsource.net provides transceiver modules that have the fastest Gigabit
