In the battle between copper wire, fiber optic cables and wireless transmission, copper has a secret weapon.
A key advantage that separates copper wire from fiber optic cables and wireless transmission is its ability to provide high bandwidth data communications and power delivery simultaneously.
A study currently is underway to determine the comparative power capacity for various enhanced copper-based local area network (LAN) cables under different environmental conditions, as well as the maximum safe power distribution capacity for data wiring.
The study also will identify target applications and develop a business case for simultaneous data communications and power delivery over copper-based Ethernet cables.
Almost all the telecommunications appliances, from phones to computers, require both data connectivity and a power supply. Telephones, for example, are powered from the telephone exchange through the same twisted pair cable that carries voice.
Power over Ethernet technology allows IP telephones, wireless LAN Access Points and other appliances to receive power as well as data over existing LAN cabling, without needing to modify the existing Ethernet infrastructure.
An international Power over Ethernet standard was adopted in 2003 as an extension to existing Ethernet standards, providing the first truly international standard for power distribution over local area network cabling. Power over Ethernet is gaining popularity now as the cost of adding power supplies to Ethernet switches is relatively small.
There are many advantages to this kind of delivery, including that only a single set of wires are needed, which simplifies installation and saves space. The appliance can be moved more easily to wherever a LAN cable can be made available with minimal additional disruption. It can be shut-down or re-set remotely (no need for a re-set button or power switch that needs to be activated at the site of the disruption), and lastly, it provides safe delivery of electricity as there are no mains voltages to connect.
If this application for copper wire is realized, this previously under-appreciated idea has the potential to extend the life of copper cables.
