General cabling requirements

Minimum curvature radius of cables
The curvature radius of an attached power cable, communication cable, or ribbon cable should be
•
at least five times the cable's outer diameter. If the cable is frequently bent, plugged and unplugged,
the curvature radius should be at least seven times the cable's outer diameter.
The curvature radius of an ordinary attached coaxial cable should be at least seven times of the
•
cable's outer diameter. If the coaxial cable is frequently bent, plugged and unplugged, the
curvature radius should be at least 10 times the cable's outer diameter.
The curvature radius of a high-speed cable (for example, SFP+ cable) should be at least five times
•
of the cable's outer diameter. If the coaxial cable is frequently bent, plugged and unplugged, the
curvature radius should be at least 10 times the cable's outer diameter.
Minimum curvature radius of fibers
When the fiber is wrapped up around the cabling plate, the diameter of the cabling plate should
•
be at least 25 times the fiber's diameter.
When the fiber is being moved, the curvature radius of the fiber should be at least 20 times the
•
fiber's diameter.
When the fiber is attached, the curvature radius of the fiber should be at least 10 times the fiber's
•
diameter.
NOTE:
The fiber's diameter refers to the outer diameter of the fiber jacket. Typically, the diameter of a single-core
fiber is 0.9 mm (0.04 in), 2.0 mm (0.08 in), or 3.0 mm (0.12 in).

Prerequisites

Label cables before you route or bundle them.
