High Pair Cable Count

When cables contain more than one pair group, different color binder tapes are used to differentiate the 25 pair groups.

Primary Insulation Color Coding

Proterial Cable uses a co-extruded color stripe to mark insulated conductors.

This process provides several benefits:

  • Marking durability is insured for the life of the cable.
  • Electrical characteristics of the marking stripe match the insulation.
  • Avoids highly toxic ink systems that are required to bond to some materials.

Note

To differentiate bundles in cables with greater than 12 strands, polyester binders or buffer tubes (depending on the construction) are used. Those binders or buffer tubes will incorporate the same color code found in the chart above. The color code is part of the TIA-598 standard. For indoor, multiunit fiber optic cables, subunits will be numbered for identification.
