Introduction
Transceivers are electronic devices which comprise a transmitter and receiver circuit in one. It does the job pf both, transmitting radio signals with the help of an antenna by converting the alternating currents into radio signals. Also, it receives the radio signals in the form of alternating currents which it again converts back into the original radio signal. With the help of filters which remove unwanted signals which might have been picked up by the antenna, these receivers get the clean and pure message signal which was transmitted. Without these filters, the receivers would not be able to distinguish between the desired and undesirable signals and the necessary useful information would have been lost.
Copper transceivers vs Optical Fibre transceivers
Today, transceivers are made of different materials suited to the different needs of their devices. 
Mainly, a fibre or copper transceiver is used in the market today. With copper transceiver providing higher performance in recent years, it is often chosen over optical fibre transceivers. The fight between these two technologies has been going on for decades with optical fibre leading in a few categories while copper leading in the rest. Copper transceiver technology has increased highly in the recent times. The choice often confuses the top IT experts and organisation as to which one is better for their future. Usually, for short range transmission, a copper transceiver is the obvious choice over optical fibre one because of its durable material. Moreover, it is cheaper and easy to handle while patching cables. Also, most switches have copper ports which are compatible with a copper transceiver but not with optical fibre. Optical fibre has a few advantages as well such as more flexibility over copper cables. With longer connections required to be made, the choice shifts towards optical fibre due to this property. Thus, copper transceivers are used when we consider short distances unto 100 m while fibre transceivers are considered which includes long distance communication.
Details regarding copper transceivers
Most transceivers in the market today are made of copper. These devices have been rigorously tested and approved to give customers the best efficiency. With excellent use for short distances, these transceivers are compatible with copper cables. Usually their maximum data rate offered is around 1.25 giga bytes per second. Also, these devices consume very low power; some even less than 1.3 watts. One can buy these products at any electronics shop or even choose to but these products online with all their details listed on their page. These transceivers also system expansion and do not produce any sort of network interruption in between. These also provide protection against all sorts of electromagnetic interference or EMI. These transceivers come in different modes of speed from 10 to 1000 megabytes per second. These transceivers are also called as Copper Small form-factor pluggable transceiver or SFP in short.
Conclusion
Thus, we can see that copper transceivers have multiple advantages. This is the reason why it is often considered to be the normal choice while opting for a transceiver.
