Cat 6 Wiring diagram

Upgrade your CAT5 wiring to CAT6 wiring


CAT 6 wiring is used to create computer and electronics networks. It uses eight different pieces of insulated CAT 6 wire. At every ends there is four pairs of insulated CAT 6 wires and each pair consists of two different color-coded insulated wires twisted together. It is a new standard in Ethernet cables which includes specification for crosstalk and system noise. CAT 6 wires is present in two different forms, plenum cables which is made up of solid copper conductor and another is non-plenum cables which is made up of braided strands of thin copper wire.


The CAT 6 wire is made up for four different installations so it has four different National Electrical Code designations which depend upon the usage. Cable which uses CAT6 wire under the NEC designation has to meet UL 1666. It has NEC designation CMR when used in vertical shaft Riser installations. CL2R and CL3R are its respective sub-designations. The NEC designation has provided level 3 of flame protection to the cable which is just lower than the plenum application. When it is used in commercial general purpose it requires meeting the CSA FT4 flame protection standard. For residence a CAT6 wire has NEC designation CMH and other two sub-designations which are CL2X and CL3X.

With the help of CAT 6 wiring diagram you can easily assemble and make network connection between the Ethernet port of a computer and a hub. To make twin connections you can use 2 TIA or EIA wiring standards at the respective ends of a CAT 6 UTP cable and 2 RJ-45 connectors. RJ-45 connector is little bit bigger than the RJ-11 telephone connector. The CAT 6 wiring diagram helps you to make connection correctly and in the right sequence. You can depict the eight wire color code which is in the eight rows in the first column and the pin number of RJ-45 connector which starts from 1 to 8 in the second column.


CAT 6 cables are great for running network speed at 1000 Mbps or more. It is future proofing for your installation and provides bandwidths of 250 MHz. You have to follow the same wiring diagram when you are using T-568-A for making the connection. The diagram is same for CAT 6 cable and CAT5e cable because of the same color codes and number of wires.
