Ethernet Over Copper Distance Limitations

Where eoc has distance limitations ethernet over fiber is not effected by these.

Ethernet over copper distance limitations.

1000base t also known as ieee 802 3ab is a standard for gigabit ethernet over copper wiring. Maximum distance over copper cable is 100 meters but because of its bandwidth requirements higher grade cables are required. T1 technology was developed by the telephone industry to provide phone line trunking between switching centers. As with dsl distance is a factor.

Cat7 gets advertised for its 100 gbps speed but that will only work for distances up to 15 meters slightly over 49 feet. 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. Provisions were made for t1 specific signal regenerators to allow t1 service to stretch just about any distance from the co. To date power over ethernet poe technology has vastly expanded the kinds of applications that system integrators and installers can support.

It should be noted that cat7 cable has harsher distance limits than cat5e cat6 and cat6a. Namely distance cable type and available power at remote stations. 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. Distance vs bandwidth the second limitation of ethernet over copper is distance.

Distance multimode singlemode media fiber copper speed suggest keywords. As far as reliability goes ethernet over copper eoc does offer some redundancy. In 2007 one million 10gbe ports were shipped in 2009 two million ports were shipped and in 2010 over three million. There are a few different versions of ethernet cable but they all have a maximum distance of 100 meters 328 feet.

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. 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.
