Binder Groups

 

For cable larger than 25 pair, the cable is separated into groups of 25 pairs called binder groups. Usually cabling vendors use two flat plastic strips, helically wrapped around each group of 25 pairs. Each strip is colored. The first strip uses one of five tip colors. The second strip uses one of five ring colors.

When the cable's pair count exceeds 600, bundles are grouped into super bundles. Every super bundle uses wrapping, colored with one of first three tip colors. It gives color codes for cables with up to 1800 pairs. For real big cables, having more than 1800 pairs, vendor-specific color coding is used.
