Physical interface and cable types
- [Presenter] The Ethernet standard defines many cabling types, with speeds from 10 megabits to 400 gigabits. The most utilized cabling type is Unshielded Twisted Pair, or UTP. UTP utilizes four pairs of copper wire, with each pair utilizing a different number of twists per inch, hence the name twisted pair. Copper cabling comes in several categories, each rated to carry traffic at different speeds at differing lengths. The next most common cabling type for Ethernet will be fiber-optic cabling. In essence, light is send down a glass strand generally with a capability for higher speed and over longer distances than copper. Examine this diagram. While is isn't an exhaustive list, it does display some of the common connection types a network admin is likely to encounter. Notice how the I triple E standards end in either a T or an L. The T represents a copper connection, while the L is indicative of a fiber connection. Modern copper Ethernet connections utilize RJ45 connections. This is…
