All information about Transceivers https://www.1000gig.com/
Transceivers may be described as devices that act as both transmitters and receivers of digital or analog signals. They are used in common devices such as radios and telephones. Transceivers are also used in LANs and other types of networks for transmitting signals.
There is some confusion over the difference between transceivers and transponders. Here’s what you should know - Transceiver transmit and receive signals at any time. Transponders are devices which respond only to incoming signals.
Transceivers are available in 3 different configurations such as a chip style, module style and board style. The chip style transceivers are portable and small in size. They can be easily separated from the network and switched to a different network. Board style transceivers are different from those of chip style as they are built within the network and are a permanent part of it. Module style transceivers are stand-alone devices. They are not installed in the network and are connected to it.
