Ethernet over copper distance limitations.

T1 technology was developed by the telephone industry to provide phone line trunking between switching centers. This consistency of ethernet between the service provider core and the customer network reduces overhead increasing performance providing a more consistent connection to the user. The speed of connectivity may reduce over greater distances between. In 2007 one million 10gbe ports were shipped in 2009 two million ports were shipped and in 2010 over three million.

Namely distance cable type and available power at remote stations. As with dsl distance is a factor. Maximum distance over copper cable is 100 meters but because of its bandwidth requirements higher grade cables are required. It runs over multiple pairs of twisted copper wires and when one strand of copper goes down the circuit remains up albeit at a lower speed.

1000base t also known as ieee 802 3ab is a standard for gigabit ethernet over copper wiring. As far as reliability goes ethernet over copper eoc does offer some redundancy. However one of the biggest considerations that you will have to pay attention to if you are looking at ethernet over copper is the distance. Provisions were made for t1 specific signal regenerators to allow t1 service to stretch just about any distance from the co.

So it s 100 meters 328 feet. Distance vs bandwidth the second limitation of ethernet over copper is distance. Distance multimode singlemode media fiber copper speed suggest keywords. Where eoc has distance limitations ethernet over fiber is not effected by these.

Cat7 gets advertised for its 100 gbps speed but that will only work for distances up to 15 meters slightly over 49 feet. A the adoption of 10 gigabit ethernet has been more gradual than previous revisions of ethernet. Ethernet over copper is an extremely affordable solution primarily because it uses traditional copper cables. Many more are expected to emerge yet the technology does have some pesky limitations.

It should be noted that cat7 cable has harsher distance limits than cat5e cat6 and cat6a. To date power over ethernet poe technology has vastly expanded the kinds of applications that system integrators and installers can support. Each 1000base t network segment can be a maximum length of 100 meters 328 feet and must use category 5 cable or better including cat 5e and cat 6.
