Despite Ethernet distance restrictions, Ethernet's popularity has steadily increased since the 1990s. As the leading computer networking technology for local area networks (LANs) today, Ethernet has largely replaced the LAN standards of the past, such as token ring and fiber-distributed data interfaces (FDDI).

Ethernet was first developed to use a shared coaxial cable linked to all machines on a network. For small networks, this was a reliable system, but as the number of peripherals and devices on a network increased, potential damage to the wire and connectors made such systems inefficient.

Hubs, repeaters and extenders have all increased the efficiency of the Ethernet as well as increased Ethernet distance and range. Due to signal degradation and timing issues, Ethernet segments are still limited in size and the speed of the signal is dependent on the medium used. A 10BASE5 coax cable, for instance, has a maximum length of 1640 feet.

Using a repeater, Ethernet distance can be extended well beyond the specified standard. The signal is taken from the cable and then repeated onto another. Repeaters can be used to connect up to five Ethernet cables. With repeaters, one damaged segment will not affect the entire network, but will instead only slow down the segment on which the damage is located.

Ethernet Extenders increase the efficiency of the Ethernet connection above and beyond the capabilities of a repeater. In addition to extending Ethernet distance, Ethernet extenders also act as filters for removing unwanted broadcasts.
