This seems like a good demarcation for the colors, but two things. Its a bit 
more expensive, and, it typically makes for a pretty mess. You're talking pre 
determined cable lengths for the most part. I tend to avoid patch cables like 
the plague and invest in long term deployments cut to length. 

Intelligently strapping in mostly permanent wiring should be worth the 
investment and reduce outages in the long run. The colors don't hurt. 

Best,

Marty

I don't know of any hard standard in use anywhere.  I've generally taken
to the following:

Green == low-bandwidth straigh-through
        Telephone, T1, Serial, etc.
Purple == Roll Cables (almost always serial, sometimes telecom)
        (8-1 7-2 6-3 5-4 4-5 3-6 2-7 1-8)
Orange(C) == EIA-568b cross-over cable (ethernet xover)
Orange(F) == Multimode Fiber
Yellow(F) == Singlemode Fiber
White == Clear (inside VPN concentrator network)
Black == Crypt (Outside VPN concentrator network)
Blue == Publicly accessible networks
Red == Backend (usually OOB management) networks
Pink == KVM (KVM switch <-> Dongle)

Occasionally I encounter needs for greater specificity, but, these
usually do most of what I need.

I'm sure others use entirely different choices.

Owen
