When the fiber is fixed, the diameter of the cabling plate should be at least 10 times the fiber’s
diameter.
The fiber’s diameter refers to the outer diameter of the fiber jacket. Generally, the diameter of a
single-core fiber is 0.9 mm, 2.0 mm, or 3.0 mm (0.04 in., 0.08 in., or 0.12 in.).
Cable Binding
Correct Use of Labels
Correctly edit the label and paste it to the right place of the bound cables. For details, refer to the
description of label usage in the appendix.
Precautions for Cable Binding
z
Bind the cables straight in the cabinet. No twisting or bending.

Cable binding example I
z
The radius of the curve at which a cable is bent should be at least twice the cable’s diameter. At the
point where a cable runs out of a connector, the radius of the curve at which the cable is bent
should be at least five times its diameter.
z
Different cables (power cable, signal cable, grounding cable, and so on.) should run and be bound
separately in a cabinet. They must not be bound together. If they are close to each other, you can
cable them in a crossing way. For parallel cabling, the space between power cable and signal cable
should be no less than 30 mm (1.18 in.);
z
The cable binding rack and cable channel inside and outside a cabinet should be smooth and
stretch no sharp points.
z
The metal hole through which a cable runs through should have a smooth and fully surface or an
insulating bush;
z
Use the right type of ties to bind the cables. Do not bind any cables with tied ties. Hangzhou H3C
technologies Co., Ltd. provides the following types of ties: 100 x 2.5 mm (3.94 x 0.10 in), 150 x 3.6
mm (5.91 x 0.14 in), 300 x 3.6 mm (11.81 x 0.14 in), 530 x 9 mm (20.87 x 0.35 in), and 580 x 13 mm
(22.83 x 0.51 in);
