A transceiver refers to a machine used in receiving and transmitting information through a channel. It can either be analog or digital; analog transceivers use frequency modulation while digital transceivers use binary data to send and receive data. In Large Area Network (LAN), the transceiver places signals and is responsible for detecting incoming signals being transmitted through the same cable. It doesn’t mean one can’t get transceivers in the external form. Transceivers are classified into different types; below are the common types according to one optical transceiver module manufacturer.
1. RF Transceivers
RF is a type of transceiver with both a receiver and transmitter. RF transceivers can be used in a broad range of activities, including in a wireless communication system such as WI-FI and Bluetooth. They are defined by their capability and strength to communicate.
2. Fiber-optic transceivers
Devices under this category use a technology called fiber optic in the transmission of data. It is an essential aspect of devices capable of decoding and encoding information into light signals. Once decoded, the messages get transmitted as electric signals.
3. Ethernet transceivers
Ethernet means a device used to connect externally, and therefore Ethernet transceivers are used in devices such as computers to receive and transmit data. They are also referred to as Media Access Unit (MAU).
4. Wireless transceivers
Wireless transceivers are an essential part of the wireless communication. It’s hard to determine the best quality since it can only be judged by how fast they transmit data.
Areas to use Transceivers
· Transceivers are used in wireless communications
· Transceivers use a wireless channel to transmit data, either in the form of data, voice, or video.
· RF transceiver is used in several communications such as radio, TV signal transmission, and satellite communication.
How does transceiver work?
In radio applications, when the signal is being transmitted, the receiver is usually inactive.
The transmitter and receiver use an electric switch through a similar channel. This is done to protect the receiver from getting damaged. Getting signals while data is being transmitted is impossible.
Therefore the receiver needs to be silenced (half-duplex). Other transceivers can only receive messages through stages known as full-duplex.
This means that the transmitter and the receiver cannot work on the same frequency, which prevents the wire from interfering with the receiver. These kinds of transceivers are used in cellular and cordless phones.
Satellite communication uses full-duplex transceivers depending on the surface. The signal used from transceiver to the satellite is called uplink; the one from a satellite to a transceiver is called downlink
There are different types of transceivers in the market today, choose the one which suits your design. When you consider the design, selecting a transceiver is made easy. One can also consult experts to know the different types of transceivers and choose one which fits your model. Relying on your chosen design means the end-user will be happy with its functionality since it will work well and for a more extended period. The expert you want should go with a transceiver that fits your design.
