For outlet UTP cable, the bend radius shall not be less than how many times the cable diameter?

• A. 2 times the diameter
• B. 3 times the diameter
• C. 4 times the diameter
• D. 6 times the diameter

Answer: (C)

A bend radius that is not too tight protects the cable’s geometry and its ability to carry a stable signal. For outlet UTP cable, the minimum bend radius is four times the cable diameter. Bending tighter than this can stress the jacket and conductors, causing microbending losses, increased attenuation, and potential impedance changes that degrade performance. Four times the diameter balances practical installation with maintaining integrity for typical Cat5e/Cat6 runs. If you tried radii of two or three times the diameter, you’d risk damage or signal loss; six times the diameter is more conservative than needed for normal outlet installations.
