![]() ![]() Ordinary ADSL modems cannot be connected back-to-back, because the ATU-R (ADSL Termination Unit - Remote) units that are used by customers require specialized ATU-C (Central Office) support provided by phone company equipment, usually by a complex and expensive DSLAM (DSL access multiplexer). The equipment is mostly simple to operate, and the connection wire is common, cheap and maintainable, as opposed to fiber optic cable. Distances of 1,000’ (300m) at 100Mbps symmetrical or up to 5 miles or more at 128 kbps is possible. ![]() Specialized equipment can inter-connect two LANs over a single twisted pair of wires using VDSL technology. Up to 656’ (200m), it may be possible to set up an ordinary Ethernet bridge or router in the middle, if power and weather protection can be arranged. If the buildings are within 328’ (100m), a normal Ethernet cable segment can be used, with due consideration of potential grounding problems between the locations. Wi-Fi requires a clear line-of-sight, special antennas, and is subject to weather. Copper-based Ethernet extenders must be used on unconditioned wire (without load coils), such as unused twisted pairs and alarm circuits.Ĭonnecting a private LAN between buildings or more distant locations is a challenge. While transmitting over copper wire does not allow for the speeds that fiber-optic transmission does, it allows the use of existing network-grade copper or CCTV coaxial cable wiring. Network extenders use various methods (line encodings), such as TC-PAM, 2B1Q or DMT, to transmit information. These devices employ a variety of transmission technologies and physical media (wireless, copper wire, fiber-optic cable, coaxial cable).Įthernet extenders forward traffic between LANs transparent to higher network-layer protocols over distances that far exceed the limitations of standard Ethernet.Įthernet extenders that use copper wire include 2-, 4-, and 8-wire variants using unconditioned copper wiring to extend a LAN. Networking DevicesĪn Ethernet extender (also network extender or LAN extender) is any device used to extend an Ethernet or network segment beyond its inherent distance limitation which is approximately 100 metres (328 ft) for most common forms of twisted pair Ethernet. On this page you will find definitions for common terms for Ethernet extenders and other networking equipment and the media they utilize. ![]() BLOG POST: Introducing the NEW Netsys G.fast Gigabit Ethernet Extender KitīLOG POST: Not All Gigabit Ethernet Extenders Are Created Equal ![]()
