High Fiber Count Cables
Color code, used in fiber optics, resembles that of copper. The major difference is 12-color sequence as oppose to 10-color for copper. The sequence of colors is the same, with addition of two colors - Rose (11-th) and Aqua (12-th).
In the high fiber count cables fibers are grouped in 6 or 12, and then the groups themselves are numbered. Therefore, the individual fiber's number equals the number of the group times 6 or 12 plus the number of the fiber in the group. The group size (6 fibers or 12) depends on the cable design and the total fiber count. Be aware that in cables with fiber count that is not a multiple of 12, especially those with more than 24 fibers, you can encounter both 6- and 12-fiber groups at the same time.
Groups of fibers can be designated in several different ways:
There are also colors that designate the type of the optical fibers. It is not always followed by all manufacturers, and also, this code only applies to indoor cables: multimode fiber cables have orange jacket, and singlemode fiber cables have yellow.
