5.1.4 Installing Cable Accessories
Precautions for Installing Cable Accessories
Tools
NOTE
The illustrations in this document may differ from actual situations, but the installation methods remain
the same. For example, in this document, the adapters of cable connectors have separate interfaces. In the
actual situation, the adapters may have interfaces fixed on equipment.
Use dedicated tools provided or specified by Huawei and follow the installation procedure
described here.
Bending Radius
Unless otherwise specified, bending radiuses (R) of cables or fibers must meet the requirements
listed in Table 5-9.
Table 5-9 Bending radiuses of cables or fibers
Cable or Fiber Bending Radius (R)
Ordinary cable
In normal cases, R ≥ 2d. When the cable is
connected with a connector, R ≥ 5d.
Fiber
R ≥ 40 mm (1.57 in.); Bending angle > 90°
NOTE
The letter d indicates the diameter of a cable or fiber.
Precautions for Installation
l Hold the terminals of cables instead of pulling the cables when installing or removing the
cable components.
l Do not insert a connector forcibly when the connector is blocked. Pull out the connector
by using a dedicated tool. Install the connector again after you check that the pins are
inserted properly.
l Before tightening screws on cable connectors, ensure that the connectors are properly
connected to their adapters. Tighten the screw with appropriate force using a flat-head or
Phillips screwdriver instead of bare hands or an electric screwdriver. If the screw cannot
be screwed into the tapped hole, find out the reason and try again. Do not screw it with too
much force, or the screw or adapter may be damaged.
