Precautions for Installing Cable Accessories

Precautions for Installing Cable Accessories

You must take precautions when installing cable accessories and follow the correct installation procedure.



Illustrations of components in this document may differ from actual components. For example, in this document the adapters of cable connectors have independent interfaces, whereas adapters may actually have interfaces fixed on equipment. However, the installation procedures are similar.

Use dedicated tools provided or specified by Huawei and use them in accordance with their specifications and instructions.

Bending Radius

Unless otherwise specified, the bending radius (R) of cables or fibers must meet the requirements listed in Table 4-9.

Table 4-9 Bending radius of cables or fibers

Cable or Fiber

Bending Radius (R)

Ordinary cable

R ≥ 5d, for the part near the cable connector R ≥ 2d, for the rest of the cable


R ≥ 40 mm

Bending angle > 90°


The letter d indicates the diameter of the cable or fiber.

Precautions for Installation

  • Hold the terminals of cables instead of pulling the cables when installing or removing the cable components.
  • Do not use excessive force when inserting a connector into an adapter. If a connector cannot be fully inserted, pull it out using a dedicated tool and ensure that you are trying to insert the connector into the correct position.
  • Before tightening screws on cable connectors, make sure that the connectors are in good contact with their adapters. Use a flat-head or Phillips screwdriver rather than hands or an electric screwdriver to tighten the screws. Stop immediately if the screws cannot be tightened. Identify the cause and rectify the fault before attempting to tighten the screws again so as to prevent damage to the connector and adapter.
  • When removing densely distributed cables or fiber connectors, use dedicated pliers such as cable-pulling pliers and fiber-pulling pliers.
  • Do not twist, bend, stretch, or squeeze fibers during installation.
  • Cover the fiber connectors that are not being used with dust-proof caps. Remove the dust-proof caps only when you are about to use the fiber connectors.

Requirements for Cable Routing

  • To protect cables, remove the burrs in the cable-through holes or install protective rings in the holes.
  • To ease the connection and to avoid stress, do not make cables too tight at cable joints. After connecting multiple cables to a connector that has multiple interfaces, keep the cables slack to avoid generating stress.
  • Bind and clean cables gently to avoid cable distortion, which affects signal quality.
  • Keep cables away from moveable objects, such as doors.
