Appendix E Cabling recommendations

When the switch is mounted in a 19-inch standard rack, the interface cables are routed through the cable
management brackets, bound at cabling racks on chassis sides, and then routed up or down to pass
through the chassis top or the raised floor, depending on the available equipment room condition. The
power cords run along the two sides of the chassis and out of the chassis either from the chassis top or
the raised floor depending on the equipment room conditions (power distribution cabinet, lightning
protection box, connector strip, and so on) of the exchange office.
General cabling requirements
Minimum curvature radius of cables
The curvature radius of an attached power cord, communication cable, or ribbon cable should be
a minimum of five times the cable's outer diameter. If the cable is frequently bent, plugged and
unplugged, the curvature radius should be a minimum of seven times the cable's outer diameter.
The curvature radius of an ordinary attached coaxial cable should be a minimum of seven times of
the cable's outer diameter. If the coaxial cable is frequently bent, plugged and unplugged, the
curvature radius should be a minimum of 10 times the cable's outer diameter.
The curvature radius of a high-speed cable (for example, SFP+ cable) should be a minimum of five
times of the cable's outer diameter. If the coaxial cable is frequently bent, plugged and unplugged,
the curvature radius should be a minimum of 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 a minimum of 25 times the fiber's diameter.
When the fiber is being moved, the curvature radius of the fiber should be a minimum of 20 times
the fiber's diameter.
When the fiber is attached, the curvature radius of the fiber should be a minimum of 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).
Before binding the cables, fill in the labels for them correctly and stick them to the right position on the
cables.
Cable management requirements
When you route and bundle up cables, follow these guidelines:
Bind and route cables neatly inside the rack, and make sure they are not kinked or bent.
