Hi Yardiel, Patch cables or fixed cabling to patch panels? For fixed cabling, it's common to pick colors which match the cable type. Orange for multimode fiber, yellow for single mode fiber, blue for four-pair cat5e, something else for cat6, etc. At each end, label the location of the opposite endpoint twice, once on the panel and once on the cable itself (cables can pull loose from panels). With fixed cabling terminating in patch panels they'll tend to get reused over time for different types of signalling so don't overthink it. For patch cables, it's common to pick a color for each type of physical signaling so you don't jam the wrong kind of signal in to a port that doesn't match. Your gig-e switch may not like the voltage from that ringing pots line. Blue for ethernet, white for POTs, green for T1s, some other color for the rs232 serial cables, IP/KVM cables, etc. I find the easiest way to label patch cables is with color electrical tape. Put the same bands of unique colors at both ends of the cable. This will let you visually identify the cables without pulling on them to try and line up tiny text on the tags with your eyeballs.
