About

Panduit Derate

This tool helps determine the maximum allowable lengths for twisted-pair copper patch and horizontal cables in compliant Category 5e, 6, or 6A channels. It allows users to define cables, create multi-cable channels, and validates configurations, providing guidance on length adjustments.

Highlights
  • Define cable type, category, gauge, and length
  • Create single or multi-cable channels
  • Validate channel configurations
  • Information on additional length
  • Guidance on length reduction for invalid channels
