I've encountered flat 8 core cable, terminated with RJ45's, used as patch
leads in a Serial environment. They were used with Baydek SMUX serial
boards, also seen them used with some Specialix terminal servers, both had
RJ45 sockets for the serial ports.
Of course, when one of my colleagues tried to use them for Ethernet we had
terrible problems. They would just about work (for the short lengths in a
patch cabinet) at 10Mbps, but were total no-no at 100Mbps.
You can use just about anything for short runs. Even 100-base-T might
work with 4-strands of random wire at some minimal distance. But if you
expect anything to run and run reliably, especially at a distance, use
properly rated cable :)
