Tim's Ethernet Patch Cable Color Codes

Tim's Ethernet Patch Cable Colour Codes

Keeping data from getting crossed in a data center can be a pain. Here is how I try to keep things sane. This is the current list of colors of ethernet cables I can find or have seen:
  1. blue
  2. light blue (rare but commonly used on cisco cables)
  3. fluorescent blue (even rarer)
  4. red (many of these are cross over cables)
  5. yellow (this was a standards approved color for cross over cables)
  6. cisco cable yellow
  7. orange
  8. pink
  9. fluorescent pink
  10. green
  11. fluorescent green (never seen this buts its in catalogs)
  12. black (easy to confused with power cords)
  13. white (sort of rare)
  14. light gray
  15. dark gray (rare)
  16. silver (rare)
  17. tan/beige (common in cat 3 patch cables)
  18. purple/violet (they are different but when you order one you get the other)
  19. fluorescent violet (very rare)
One thing to consider is about 15% of all males are slighly color blind and only about 10% think they are. Many colors look the same but often times a color blind person can easliy tell the difference between say tan cables and beige cables but can't tell the red from the green.

Color codes for fiber (fibre?)

Color codes for fiber jackets Note that buildings will often have these colors: For -48 volt systems you can get:

Note that -48 Volt systems tend to be able to provide massive amounts of unfused current. These system will often have enough capacity to boil the metal in tools.

That describes the outer jackets. Inside cables like power you can have:
Live power from selected places around the world:

The color codes for ships make much more sense and are about as uniform. For example blue is used for compressed air on US registered ships yet blue is for water on UK registered ships.
