About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Building a fibre-optic network calls for a lot of planning and consideration of many factors. Transceivers are part of the many devices used to build optical fibre systems. A transceiver serves the combined roles of a transmitter and a receiver in that it transmits and receives signals. They are most common in communication equipment such as cellular phones, cordless telephone sets, and radios. Small form factors are required as networks become dense and space is limited, which sees transceivers included in chipsets.

In local area networks (LAN), a transceiver is used to connect a computer to printers and other devices on the network. Usually, the transceiver is integrated into the Network Interface Card (NIC)

Typical Roles of a Transceiver

  • Used to convert frequencies from IF to RF.
  • Widespread use in wireless communication to transmit data – voice, data, and video.
  • RF transceivers are used in communication devices to support radio and TV signal transmission, digital signals transmission, and satellite communication.
  • Collision detection – detection of simultaneous signals on the network.
  • Transceivers can be deployed to provide a jabber function to interrupt the transmission of long data stream outputs.

Look no further for all types of transceivers including fibre optic transceivers, wireless transceivers, Ethernet transceivers, and RF transceivers. All these transceivers have different characteristics and support full-duplex communication, but the principle behind their work remains the same. Different types of transceivers will have varying numbers of ports used in the transceiver networking connections.

RF Transceivers: these devices are used to transmit video or voice data over a wireless medium. Commonly used for satellite communication, radio transmission, and ITE/WiMax/WLAN networks. The radio transceiver works by silencing the receiver when it is transmitting. There is an electronic switch that facilitates the connection of both the receiver and transmitter on the same antenna. The switch protects the receiver from damage that may be caused by the transmitter output.

Fiber Optic Transceivers: Also referred to as optical modules or fibre optical transceivers. Used to transmit data in fibre optic technology. The network must also have electronic components to encode or decode data into light signals.

Ethernet Transceivers: Basically used to connect electronic devices in a network so that they are able to transmit and receive data. It is also referred to as a media access unit (MAU). The best application of these transceivers is in the specification of IEEE 802.3 and Ethernet. Ethernet transceivers will detect a collision, provide Ethernet interface processing, convert digital data, and provide access to the network.

Wireless Transceivers: Wireless transceivers are a fundamental component necessary for data delivery in wireless networks. These transceivers have two layers. The physical layer has a baseband processor and RF front end. The processor converts a bitstream to a collection symbol flow for data transmission. The second layer is a MAC layer for link traffic control in contacting wireless links, improving data throughput, and preventing collisions.
