For the outside, there is no real standard color that
I'm aware of,
although
there is a standard ordering for the wires when
crimping (I think it goes
orange, green, brown, blue (solid followed by white and color) but don't
quote me on that---it's been awhile since I've crimped CAT5 network
cables).
Not quite. It's white-with-colour then plain colour (or colour with a thin
white stripe or rings), and the common order in Europe is T568B (aka 258A):
white/orange pin 1
orange
white/green
blue
white/blue
green
white/brown
brown pin 8
I believe the common order in the States is to swap orange and green pairs,
which is T568A. If you use one scheme at one end and the other scheme at
the opposite end, you have a standard Ethernet crossover cable. ie, pins 1
and 2 are swapped with pins 3 and 6 but pins 4+5 and 7+8 are
straight-through.
But for a regular CAT5 cable, as long as you use the
same order for each
end, it'll work fine.
Almost. You need to keep the pairs as pairs, on pins 1/2, 3/6, 4/5, and
7/8.
