Network transceivers connect network nodes and send and receive analog or digital signals. In Ethernet networks, they are called medium access units (MAU). Network transceivers apply signals onto a network wire and detect signals passing through the same wire. In local area networks (LAN), they may be used with networking repeaters, devices that regenerate or re-time signals to ensure that these signals are transmitted through all network segments.

This diagram describes the role of transmitter-receivers in a thick Ethernet network. Attachment unit interface (AUI) connections provide a path between each node's Ethernet interface and the MAU.

Types of Network Transceivers

There are two basic types of network receivers: board and module.

• Board-style devices are network interface cards (NIC) that plug-in to a computer motherboard. They are more difficult to remove than chip-style devices, but also still classified as internal transmitter-receivers.
• Modular products are stand-alone devices. They are external network transmitter-receivers.

Specifications

The Engineering360 SpecSearch database provides detailed information about network transceivers that use various network protocols (e.g., Ethernet, Token Ring). Industrial buyers should remember to specify the number of ports or channels through which the transceiver will connect to other devices. Additional product and performance specifications cover associated peripherals and the type of connection ports.

Features and Applications

Network transceivers that use industrial protocols such as CANbus are used both in automotive and general industrial applications. Features for network transmitter-receivers include low-power management and fault protection.
