A transceiver is a device that can be found in fiber optics networks. It is an electronic device that can transmit and receive signals simultaneously. So, a transceiver can be defined as a combination of a transmitter and receiver in one package.
A transceiver is typically used for wireless communication devices, but it can also be used to send and receive signals in optic fiber and cable systems. Thus, its main job is to send and receive different signals.
In LAN (local area networks), a transceiver is a separate piece of hardware that is added to the network, and it can transmit signals through the network wire. Also, it can detect electrical signals flowing through the wire.
On the other hand, in WLAN (wireless local area network), the transceiver is built into the device itself.
- RF transceivers. An RF transceiver is a device or module used in routers and baseband modems for analog and digital transmissions. A common use case of RF transceivers can be found in satellite communications networks.
- Fiber-optic transceivers. An optic or optical transceiver is a device that can receive and send data across long distances and at high speeds. It is used for converting electronic signals into light signals.
- Ethernet transceivers. An ethernet transceiver is a hardware device that connects electronic devices, like computers, within a certain network. It is also known as a media access unit.
- Wireless transceivers. A wireless transceiver is a combination of an ethernet and RF transceiver. It is used to improve the transmission speed of WiFi networks.
