In high fiber count cables fibers are grouped in 6 or 12,and then the groups themselves are numbered.

Groups of fibers can be designated in different ways:

  • Fibers are housed inside of colored plastic tubes (or wrapped in colored threads or plastic ribbons): colors of the tubes go in the same sequence of the fibers: Blue, Orange, Green, etc.
  • Fibers have black stries , one, two, three or even four.
