Cat 5E


- This is the connector on a Category 5 Enhanced, better known as Cat 5E, Ethernet patch cable used to connect a computer to a wired network. The cable has eight wires in four twisted pairs although in most cases only two pairs are used for communications. Each pair has a different distance between twists. This alternating distance reduces crosstalk, without affecting the characteristic impedance. The distance per twist is commonly referred to as pitch. Each pair contains between 51.7 and 65.2 twists per meter. How's that for dose of geek talk. Enough techno babel, here's some photo speak - Canon 7D, 1/40 sec @ f/5.6, ISO 800, 100mm macro focused at about 12 inches from the subject. Light is from one LED Litepanel.
