1. Are the connectors for Category 5e and Category 6 different? Why are they more expensive?
Although Category 6 and Category 5e connectors may look alike, Category 6 connectors have much better transmission performance. For example, at 100 MHz, NEXT of a Category 5e connector is 43 decibels (dB), while NEXT of a Category 6 connector is 54 dB. This means that a Category 6 connector couples about 1/12 of the power that a Category 5e connector couples from one pair to another pair. Conversely, one can say that a Category 6 connector is 12 times less "noisy" compared to a Category 5e connector. This vast improvement in performance was achieved with new technology, new processes, better materials and significant R&D resources, leading to higher costs for manufacturers.
2. How can I determine the installation requirements for CAT 6 such as termination, minimum radius around corners, proximity to electrical devices (ballasts, wiring, etc.)?
The requirements for installation of Category 6 are essentially the same as the requirements for Category 5e. Installation practices are in the TIA-568-B.1 and TIA-569-A documents.
3. Which standard addresses the combination of electrical cable and CAT 6 regarding performance or sensitivity?
I'm an ICT Consultant for a university and in process of designing the infrastructure for them. They are using CAT 6 cable as horizontal cabling and fiber optic as backbone. We are facing a problem with M & E consultant on the trunking design. They are proposing the use of a 4-way service box which contains cables for electrical and CAT 6. We cannot find in the standard about the combination of electrical cable and CAT 6 cabling either of performance or sensitivity. TIA/EIA-569 (click here for the series) "Commercial Building Standard for Telecommunications Pathways and Spaces" includes all necessary provisions for service boxes and enclosures. There are no special considerations associated with CAT 6 cabling.
4. What will happen if I mix and match different manufacturers' hardware?
If the components are Category 6 compliant, then you will be assured of Category 6 performance. Consult the manufacturer for specific warranty provisions that may be applicable.
