I believe there are 4 cables inside the UTP cable that are "active" for data, the rest might be for activity and other stuff. I need to know which colors represent the data transfer from an UTP ?
Or am I wrong ? Thanks.
This site hopefully will provide you with what you need! I belive for standard ethernet cable its pairs 1/2, 3/6, 4/5 and 7/8
It's not black and white. For 10/100 its pairs 1/2 (transmit), and 3/6 (receive) - unless you're using equipment that can autonegotiate. For gigabit, all pairs are used. The above links are all also correct. I'm not sure about 10GigE.
