Category 5 ( Cat 5 ) Cable Information

If you are looking for information about the Category 5 cable, you have found it. In this article you will learn what a Category 5 cable is, what is it for, and what should you look for in order to make sure it meets the requested standards. After reading this article you will have all the information you need for purchasing the right Cat-5 cable.

A category 5 cable, also known as a cat-5 cable or an Ethernet cable, is an existing industry standard for telephone and network wiring. It is a network cabling consisting of four twisted pairs of 24-gauge copper wire which terminate in RJ45 connectors. This cable is used for connecting computers to LANs, token ring, ATM, 10Base-T, 100Base-T, and 1000Base-T networking.

A category 5 cable can speed up to 1000 Mbps and supports frequencies up to 100 MHz. Ths way, it is used to replace the old Cat-3 cable, which couldn’t carry data over a speed of 10 Mbps. At the same time, a newer, Cat-6 cable is soon to replace the current Cat-5.

Category 5 is built according to the EIA/TIA 568 Commercial Building Telecommunications Wiring Standard, as it was developed in 1985 by the Electronics Industries Association as a request for the Computer Communications Industry Association. If you buy a wire with a “Cat-5” printed on the outer shielding, that means it is a certified category 5 cable. You can buy it in many standard lengths with RJ45 connectors already attached, or you can also purchase it off a spool in a requested length. Category 5 cables come in different colors in the outer sheath. The twisted pairs on the inside are also covered in plastic in customary colors: orange, blue, green and brown. These twisted pairs, each with a precise number of twists per meter, are used for reducing interference and should be left twisted with the exception of the last ½ inch –necessary to make the connections.

There are different configurations for wiring the RJ45 connectors:

- Straight through: It is the pinout for a category 5 cable that runs from the computer to a switch. - Crossover: Indicated if two or more computers are connected. - Roll-over: It is for connecting a computer to a router.

Now that you know what a Category 5 cable is and what is it for, you can buy it in many different places, such as home improvement centers, computer outlets or electronic stores. You can also buy your category 5 cable online.

Category 6 ethernet cable

Category 6 ( Cat 6 ) Cable Information

A Category 6 cable also known as CAT6, is one that is made up of different hardware such as connection hardware, cords and cables and is used for the Ethernet. It was developed based on test parameters and procedures to ensure that this cable has the capability to work with other cables. This cable has a lot of similarities with the previous cable, the Category 5 cable. The fact that the Category 6 cable is interoperable means that it can be used for mixing and matching with other lower categories of network cables to form a cat6 channel which is fully compliant. This cable is also backward compatible, meaning that it can be used in place of a lower category cable (for instance, the CAT5) and gives the performance of that particular cable.

The concept of being backward compliant proved to be very challenging to the manufacturers, as the features of the Category 6 cable were not easily created by them, even though they were highly beneficial to the end users of the product. The components of the CAT6 are very much similar to that of its predecessor, the CAT5. This include 100 Ohms of nominal impedance, with the Cat6 having a higher tolerance of the variations of impedance. The variations of impedance are specifically done in terms of the return loss parameter. This means that if there is a high value of return loss dB then the impedance matching of the components presents a lower signal for reflections as well as re-reflections. The Category 6 cable will provide a better bit rate error for performance with a fast Ethernet speed and a gigabyte Ethernet speed.

If your networking devices are operating in unproductive cycles for the detection or re-transmission of errors, or both, then your bit errors would end up occurring more frequently. If you experience a lower amount of bit errors, then your network is accurately transferring your data. The category 6 cable also has a higher MHz than the category 5 cable to enhance the performance of the transmission parameters of the cable. This latest cable (CAT6) has effectively doubled the top speed for that of its predecessor.

There is a huge difference with the construction of the Category 6 cable, on the outside, these cables have a larger diameter and this is dependent on the design. The diameters for the cables are ranged from 0.21-0.25 inches. The category 5 was a bit smaller.

Because of the fact that the Category 6 cables were manufactured with the addition of larger copper conductors and include an internal divider which is known as a cross-web which basically works to separate the cable pairs with an aim to reduce the noise that is received from cross-talk. The use of the cross-web divider is to separate the pairs and this is not specifically a requirement based on the standard of the Category 6. Many manufacturers have worked assiduously to develop processes and designs which deliver a full compliance of the CAT6 without having to use dividers between the pairs. There are many other features and information on the category 6 component which makes it better than the previous cables.
