*Usually* today 10BaseT and 100BaseT cables are made from the same cable,
Catagory 5. In earlier times, 10BaseT was often made from Catagory 3
cable, which isn't spec'ed to be able to carry 100Mbps signals reliably.
Yes, both use RJ45 connectors and have the same pinouts. A strait-through
cable would be defined by the following pins being connected on both ends:
1 white/green 1
2 green 2
3 white/orange 3
4 blue 4
5 white/blue 5
6 orange 6
7 white/brown 7
8 brown 8
In reality, only pins 1, 2, 3 and 6 are used in a full-duplex
configuration. The others are not used in ethernet applications.
A cross-over cable is one which connects the receive ends to the transmit
ends, thereby eliminating the need for a hub in the middle. The pine would
be connected as follows:
1 white/green 3
2 green 6
3 white/orange 1
4 blue 7
5 white/blue 8
6 orange 2
7 white/brown 4
8 brown 5
