CAT 6 Installation

Category 6 cable, commonly referred to as Cat-6, is a cable standard for Gigabit Ethernet and other network protocols. It is backward compatible with the Category 5/5e. Cat-6 features more stringent specifications for crosstalk and system noise.

Category 6 and 6a cable must be properly installed and terminated to meet specifications. Incorrect installation practices include kinking the cable or bending it with too tight a radius. Incorrect termination practices include untwisting the wire pairs or stripping the outer jacket back too far.

Shielded Category 6a cable must have the foil grounded at one end to achieve specified alien crosstalk performance. Unshielded Category 6a cable does not have this limitation, but has a larger diameter.

To ensure that an installation will meet the requirements for the network protocol it will be used for, a new installation is usually certified using a cable certifier, validator or qualification tester.

JT Low Voltage specializes in CAT6 installations. We take pride in our work, ensuring that each CAT 6 project meets TIA/EIA-568-B standards.

What is the difference between CAT 5 and CAT6?
The general difference between CAT 5e and CAT6 is in the transmission performance and extension of the available bandwidth. CAT 5e provides 100 MHz of bandwidth while CAT 6 provides 250MHz. CAT 6 includes better insertion loss, near end crosstalk (NEXT), return loss, and equal level far end crosstalk (ELFEXT). These improvements provide a higher signal-to-noise ratio, allowing higher reliability for current applications and higher data rates for future applications.
Will CAT 6 replace CAT 5?
Yes, analyst predictions and independent polls indicate that 80 to 90 percent of all new installations will be cabled with category 6. The fact that category 6 link and channel requirements are backward compatible to category 5e makes it very easy for customers to choose category 6 and supersede category 5e in their networks. Applications that worked over category 5e will work over category 6.
When should I install CAT 6 vs. CAT 5?
From a future proofing perspective, it is always better to install the best cabling available. This is because it is so difficult to replace cabling inside walls, in ducts under floors and other difficult places to access. The rationale is that cabling will last at least 10 years and will support at least four to five generations of equipment during that time. If future equipment running at much higher data rates requires better cabling, it will be very expensive to pull out category 5e cabling at a later time to install category 6 cabling. So why not do it for a premium of about 20 percent over category 5e on an installed basis?
