A color chart for the cable in front of you
Pick loose tube or ribbon and any count from 6 to 6,912 fibers. The chart lays out one row per tube with the fiber number in every cell, so there is nothing to count off by hand.
On the website
Any configuration, free to look at on the website. No sign-in; it needs a connection. Share or bookmark the link to come back to the same cable.
