Lan Cable

Lan cable include CAT7 Lan Cable, cat6a cable, cat6 cable, cat5e cable.
The length of the lan cable are 1000ft (305m), the usable part of a box cable is about 300 meters. To press the RJ45 connectors, usually needs to consider the consumption of part of zhuan degree, so one box of lan cable is 305 meters.
Home Network Cable is called "twisted pair". About twisted pair:
Twisted Pair (TP), the most commonly used transmission medium in comprehensive wiring projects, consists of two insulated copper wires. By stranding two insulated copper wires together at a certain density, the radio waves emitted by each wire during transmission are offset by those from the other wire, effectively reducing the degree of signal interference.

Twisted-pair wires are usually made of two 22-26 insulated copper wires wrapped around each other, hence the name "twisted-pair wire".In practice, twisted pair consists of several pairs of twisted pair wrapped together in an insulated cable sleeve.If one or more pairs of twisted-wire is placed in an insulating bushing, it becomes a twisted-wire cable. However, in daily life, "twisted-wire" is generally referred to as "twisted-wire".
