Ethernet Media Converter

Definition - What does Ethernet Media Converter mean?

An Ethernet media converter is a device designed to interconnect different networking media such as fiber and coaxial cables to facilitate communication between them. It often comes in the form of a small box where the two different networking cables can be plugged in.

Techopedia explains Ethernet Media Converter

An Ethernet media converter allows Ethernet communication to work properly despite the difference in the network cabling media being used. Typically, it is used to connect fiber media from an optical fiber network to a more conventional copper-based Ethernet network.

There are essentially three types of Ethernet media converters:

Standalone unit - This is a small portable box that can simply be placed anywhere the connection is made. This is used in places where only one or two conversions are needed. Because it is light weight, it can be mounted easily on a wall using strong double-sided tape or other forms of mounting, or simply left on the surface as it is inconspicuous enough.

Card-based chassis - This is often used in large main distribution frame (MDF) or intermediate distribution frame (IDF) locations where multiple optical fiber links are converted into unshielded twisted pair (UTP) links so that they can directly plug into conventional switches or routers. This can be as large as a single-to-double (2U) rack server.
