In cable supply, we deal with ethernet cable of all kinds. Cat.6 is one of them. Twisted pair cable is the standard for data communication because of its greater bandwidth and "cross-talk" minimization capabilities. Cross-talk is electrical interference from outside sources that disrupts the normal flow of data in a cable. Category 6 (Cat.6) cable can use high frequencies that enable it to reach up to 10 Gb/s transfer rate. With the use of higher frequencies, careful planning through intelligent cable design and implementation is required to avoid cross talk
If you strip back a twisted pair cable of a cat.6 and ethernet cable, you will notice that each pair has a different twist rate. These twists help reduce the rate of interference between each pair of wires. When multiple cables run parallel to each other, all pairs of the same color will have identical twist rates. When the cables are energized to 10 GB/s frequencies, the pairs might interfere with each other and produce cross-talk. At this time, there is no software remedy for this situation and we must therefore rely solely on the cable design and implementation.
If you run multiple cables parallel to each other, there are a few measures you can take to minimize cross talk. When punching down to a patch panel, use shielded patch cords. Staggering cables on the patch panel by punching down only to odd or even can also help reduce interference.
Using proper cabling practices and techniques will decrease the chance of interference, but the type of cable being used is also important. Augmented Category 6 UTP, also referred to as CAT6A, enlarges the overall diameter of the cable to increase the distances between the twisted pairs. This technique decreases the amount of cross talk and also increases the overall length capability to 100m. When using CAT6A, be sure to take into consideration the increased diameter when large amounts of cable are being installed in one location.
With the today's technology-driven market, the demand for higher data transmission rates will always be present. Manufacturers will design cable to reduce cross talk and data interference but cable installers must also design their networks intelligently as well. With the correct cable and implementation, your client's business network will provide the stable and high performing environment required to grow successfully.

Bulk Ethernet Cable
Data lines require all four pairs however four voice lines could be used on the same cable because voice only requires one pair. This could be useful if one were running four separate lines to a single location; just one cable could be punched down onto four separate RJ11 jacks. They commonly come in three colors: white, blue and black. The color does not affect the performance of the cable in any way but can be useful when running multiple lines. For example: all data lines could be run on blue cable and all voice lines could be run on only white cables to easily differentiate your groups of cables expediting the drop and termination of the cable. Our cat6 bulk Ethernet cable is backwards compatible with our bulk cat5e cable and even cat3; however, if a lower graded jack is used with cat6 cable it does reduce it to that grade of cable qualtiy; similarly if a cat6 jack were used to terminate a cat5e cable it would have no cat6 qualities. The main difference between cat6 and cat5e cable is that cat6 has reduced crosstalk or EMI (Electro-Magnetic-Interference) and where cat5 and cat5e have a 100 MHz performance, cat6 can perform up to 250MHz, and cat6e can perform all the way to 500MHz. Crosstalk is an undesired affect that occurs when other nearby cables, motors, the electrical fallout from a nuclear blast or other electronic devices interfere with the transmission on each cable therefore slowing down the flow of information or possibly cutting it off all together. Crosstalk can be greatly reduced in Cat5 and Cat6 cable by buying bulk Ethernet cable that is shielded. Shielded cable has an aluminum shield around the four twisted pairs; this shield absorbs any potential crosstalk or EMI but this electricity needs to be drained somewhere so the cable also has a drain wire that must be connected to a ground. Though there are many options for bulk Ethernet patch cables, learning which cable best suits your needs is important but being over prepared for your needs is not a bad decision as your cable will most likely outlive your devices which will require higher grade cable as time goes on.
