Ethernet Cables – The Purpose Of Ethernet Cables

When it comes to working in technology and computers, there are specific cables designed to meet specific needs and purposes. For the purpose of connecting to a high speed internet connection, Ethernet cables are what you are going to use. Ethernet cords connect to your computer and a cable modem, allowing you to reach the internet through the cable modem. Ethernet cords are useful both for wired internet connections and network setups as well. Ethernet can transfer data of up to 10 mbps, with Fast Ethernet transferring at 100 mbps and Gigabit Ethernet transferring at 1000 mbps.

There are a number of different ways that you can connect to the internet. One of the more common ways of connecting to the internet is with the use of Ethernet cables. Ethernet, connected with a cable modem, allows you to reach the internet at high transfer speeds. Ethernet cords are used both for internet setups and wired Ethernet LAN connections.

The Ethernet cord is responsible for connecting the cable modem to the computer. They are available in different types, including 10BASE-T Ethernet, 100BASE-T Ethernet, Gigabit Ethernet and so on. Respectively, these Ethernet cords transfer data at 10, 100 and 1000 megabits per second.

The connector ends on Ethernet cables are just slightly larger in comparison to the head connectors on telephone cords. Ethernet cords come in a wide variety of different lengths, allowing you to find one commercially available that suits your needs or the needs of your set up.

Fiber Optic Cables

In a world constantly seeking new ways to do things faster and more efficient, data transfer is no exception. Traditional copper wiring is rapidly making way for fiber optic cables. This innovative data transfer medium offers a faster, more efficient way to send and receive information as well as provide a great deal of communication networks for commercial offices and industrial buildings.

Here is a guide to how they work.

Speed: Light versus Electricity. Traditional copper cables send the information down the copper line to the other end. Fiber optics transfer data using light pulses as opposed to electric signals, like those transmitted with copper cables. Light sends a much clearer and faster signal.

This might seem unlikely, considering cables are enclosed in rubber tubing. But fiber optic cables are made from long, thin strands of glass or plastic. These pieces work to reflect light down the strip. To give yourself a visual, picture a hollow tube. Now mentally line the casing with tiny mirrors. Any light shined in would reflect off the mirrors one by one until it exited through the opposite end. Since light travels faster than electricity, the result of this set-up is a rapid, clear signal with less disturbances than traditional materials experience.
