What are Ethernet Cables

Written by: Tektel Team

They are cables used for wiring networks by connecting devices (computers, routers & switches) on a LAN (Local Area Network). 

They carry broadband signal between the network’s different components (compuWiring Your Home Network 1ter, router, modem and any additional internet capable device).

Generally, Ethernet cables are made with 8 wires that are twisted into 4 pairs. The pairs are color coded with a solid color and its respective dashed/striped white.

Ethernet cables are made in two conductor formats – solid and stranded.

A solid conductor cable is used for wiring buildings. Since it is a single conductor, it is easy to punch down onto wall jacks and patch panels. 

For best results, use solid for wall jacks and stranded for crimp connectors. A Stranded conductor cable is typically used for terminating standard RJ45 connectors to create patch cables. The cable itself is more flexible, and rolls up well.

There are UTP and STP Ethernet cables available. UTP (Unshielded Twisted Pair) is the more common of the two, and it has bundled wires inside a polyethylene jacket with no additional protection. UTP cables are best used for home and office networks, and where there is relative low degree of electromagnetic interference.

STP (Shielded Twisted Pair) cables have a protective metallic foil designed to shield the signal from electrical interference and allow it to carry data at a faster speed.

Selecting the appropriate Ethernet cable per installation is crucial, but properly installing and maintaining the cable is equally important for best results.
