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.
Table
The letter d indicates the diameter of a cable or fiber.
Hold the terminals of cables instead of pulling the cables when installing or removing the
cable components.
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.
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.
When removing densely aligned cables or fiber connectors, use dedicated pliers such as
cable-pulling pliers and fiber-pulling pliers.
Do not twist, bend, stretch, or extrude fibers during installation.
Cover the fiber connectors that are not in use by using dustproof caps. Remove the
dustproof caps before using the fiber connectors.
