Ethernet Extenders: The Sensible Alternative
TMCnet Web Editor
extenders are cost-effective alternatives to more complicated and pricey wiring installations such as CAT5 cable. Ethernet extenders are plug-and-play devices that you can install quickly to take advantage of existing copper twisted-pair network infrastructure. Depending on the required data rate, some Ethernet extender models can increase the distance of an Ethernet link extension beyond five miles.
Ethernet Extenders eliminate the need for installing expensive 802.3 repeaters, twisted pair (CAT5/CAT6) cabling, or fiber and associated fiber transceivers. Ethernet Extenders provide the most cost effective solutions for any LAN extension project, including Wireless Access Point (News
) installation, POE (Power over Ethernet), IP
Security Camera and POS (Point of Sale) applications.
Ethernet extenders allow users to expand their Ethernet connections beyond the 328-foot (100-meter) Ethernet distance limitations. Ethernet extenders can establish long-range, high-speed data communication links between geographically separated LANs or LAN
devices. Ethernet extenders are often employed to connect workgroups on different floors within a building.
One solution to the distance issue and to supporting POE at the same time is to use an Enable-IT 820 unpowered Ethernet extender. It was designed to carry Ethernet data over the standard 2-wire pairs (pins 1/2 and 3/6) and POE power over the spare pairs (pins 4/5 and 7/8).
