Which mechanism causes signal attenuation in unshielded twisted pair ethernet cable at high frequencies?

A)Increased skin effect resistance
B)Capacitive coupling between wires
C)Electromagnetic interference from external sources
D)Signal reflections due to impedance mismatch

💡 Explanation

When frequency increases induced capacitive coupling increases because parasitic capacitance grows proportionally with frequency, leading to signal leakage and crosstalk which attenuates signal. Therefore the signal degrades due to capacitive coupling rather than resistance, interference, or reflections alone which require different factors.
