Cabling Channel (TIA-568)
Check whether a run meets the 100 m channel limit (90 m horizontal + patch cords) by category and speed.
Conduit / Tray Fill
Compute the fill percentage of a conduit or cable tray from the cables and their outer diameter, with the NEC fill limit.
Patch Panel Planner
Compute patch panels and rack space (U) for a number of network drops, with growth reserve and cable managers.
Color Code (T568 / Fiber)
Show the T568A and T568B pinout (straight and crossover) and the TIA-598-C fiber color code by position.
