An ethernet extender (also network extender) is any device used to extend an ethernet segment beyond its normal distance limitation which is approximately 100 metres (330 ft) for most common forms of Ethernet. These devices employ a variety of transmission technologies and physical media (copper wire, fiber-optic cable, coaxial cable).
Extenders that use copper wire include 2- and 4-wire variants using unconditioned copper wiring to extend a LANs. Network extenders use various methods (line encodings), such as TC-PAM, 2B1Q or DMT, to transmit information. While transmitting over copper wire does not allow for the speeds that fiber-optic transmission does, it allows the use of existing voice-grade copper wiring. Copper-based Ethernet extenders must be used on unconditioned wire, ie without load coils, such as unused twisted pairs and alarm circuits.
