What is the minimum bend radius of 4 pair UTP cables?

Explanation:
Bending a 4-pair UTP cable too tightly can deform the cable and disturb the twisted-pair geometry, which degrades electrical performance. The minimum bend radius for copper UTP is four times the cable’s diameter, because this radius provides enough clearance to prevent kinking, maintain the pair twists, and preserve impedance. Bends tighter than this (two times the diameter) risk damage and signal loss, while much larger radii (six or eight times) are unnecessarily conservative for typical installations and impractical to fit in routes. Keeping to four times the diameter is the standard guideline to ensure reliable performance in normal network cabling.
