Which statement best describes the 90 meter rule in horizontal distribution?

The 90 meter rule focuses on how long the horizontal cabling can be from the work area outlet back to the distribution point to keep the signal within design limits. Keeping the fixed horizontal run at or below 90 meters helps control attenuation and preserves the cable’s performance so the chosen category (like Cat5e/Cat6) can reliably support the intended data rates. You’re allowed up to 10 meters of patch or workspace cords in the work area, which together with the 90 meters brings the total channel length to 100 meters—the maximum typically allowed by structured cabling standards. This rule isn’t about the minimum frequency, the number of panels, or cable color codes; those aspects are separate and don’t dictate the distance constraint.
