What is the minimum bend radius for outlet UTP cable expressed as a multiple of the diameter?

• A. Four times
• B. Two times
• C. Eight times
• D. Ten times

Answer: (A)

Maintaining a gentle bend on UTP cable preserves its electrical performance. Twisted-pair cables rely on a consistent geometry to keep impedance and signal integrity; bending them too tightly creates micro-bends and stress that can increase insertion loss, crosstalk, and long-term damage to the jacket and conductors. The minimum bend radius for outlet UTP cable, expressed as a multiple of the cable diameter, is four times the diameter. So if the cable diameter is D, the bend radius should be at least 4D. This is the smallest bend that reliably protects performance and longevity. Bends tighter than this can degrade performance, while larger radii are safe but not the minimum requirement.
