What is the Maximum
Ethernet Cable Length?

Ethernet has a distance limit of 100 Meters, or 328 feet. Consequently, cable runs should be kept under 100 Meters.

If you have a LAN segment that is longer than 100 Meters, you can still use that copper cable by using devices called Ethernet Extenders.  Ethernet Extenders enable copper network segments to be extended as far as 6 miles.

Most Ethernet Extenders work over a single twisted pair of copper wire in a CAT3, CAT5, or CAT6 cable.  They convert Ethernet to some form of DSL...then back to Ethernet at the far end.  Ethernet Extenders are typically sold in pairs with a unit for each end, local and remote.  They use different DSL modulation schemes depending on the distance and bandwidth requirements for the application.
