← ScienceWhich risk increases significantly when exceeding cable's CAT rating?
A)Increased electromagnetic interference✓
B)Elevated optical dispersion
C)Reduced current carrying ability
D)Amplified skin effect resistance
💡 Explanation
Faster signals above CAT ratings cause electromagnetic interference because cable is only shielded and designed to suppress Crosstalk up to its rated bandwidth value therefore signal integrity degrades, rather than effects caused by fiber optics, heat, or AC impedance, which are irrelevant.
