Cabling Channel (TIA-568)
Check whether a copper run meets the TIA-568 channel model: a permanent (horizontal) link of up to 90 m plus patch cords, for a total channel of up to 100 m. The real limit depends on category and speed. 100% in your browser.

How it is calculated · the TIA-568 channel model
1. The permanent link is the fixed horizontal
run (rack → outlet): maximum 90 m.
2. The channel is the permanent link plus the
patch cords at both ends: channel = horizontal + patch, with a reference
maximum of 100 m.
3. The real limit depends on category and speed.
E.g.: Cat6 supports 10G only up to 55 m; Cat6A reaches 100 m
at 10G; Cat5e supports neither 5G nor 10G.
4. Verdict: pass if horizontal ≤ 90 m and channel
≤ limit; unsupported if that category cannot run the speed;
exceeds if the channel is over the applicable limit.
5. The real limit also depends on cable quality, connectors,
temperature and alien crosstalk (interference between adjacent cables).
