• One distribution box/junction
box for each branch.
• Connecting the installation
and patch cables via the
distribution box. Use either
ST or SC plug-in connectors.

Connector type ST or SC, for example, in line with the other
comp-CPU (CPU 1517H-3 PN)
② Additional distribution boxes, if necessary, for example with SC or ST couplers. This allows you
to combine individual sections to achieve the required total length (maximum of 10 km) of fiberoptic
cable.
③ Patch cable (duplex), for example LC-SC/ST
④ Distribution box, for example with SC or ST couplers
Figure 5-9 Fiber-optic cables, installation through distribution boxesFiber-optic cables may only be laid by trained specialist personnel. Comply with all
applicable regulations and statutory requirements.
In practice, the installation of fiber-optic cables represents the most common cause of errors
and failures. These can be caused by:
● Kinks in the fiber-optic cable due to an insufficient bending radius
● Crushing as a result of excessive force caused by persons treading on the cable, by
pinching, or by other heavy cables
● Overstretching due to high tensile forces
● Damage caused by sharp edges
Quality assurance on site
Check the following points before laying the fiber-optic cables:
● Has the correct fiber-optic cable been delivered?
● Is there any visible transport damage to the product?
● Have you organized suitable intermediate on-site storage for the fiber-optic cables?
● Does the category of cable match that of the connecting components?
Storage of fiber-optic cables
Store fiber-optic cables in a place where they are protected from mechanical and thermal
factors.
Observe the permitted storage temperatures. These are specified in the data sheet for the
fiber-optic cable. If possible, do not remove fiber-optic cables from their original packaging
until you are about to install them.
Permitted bending radii for pre-assembled cables
You may not go below the following bending radii when laying the fiber-optic cables:

Next to connector: 55 mm
● During installation: 60 mm (repeatedly)
● After installation: 40 mm (onceNote the following points when laying fiber-optic cables:
● Fiber-optic cables can be installed in open locations provided you can safely exclude any
damage in those areas (vertical risers, connecting shafts, telecommunications
switchboard rooms, etc.).
● Attach fiber-optic cables to mounting rails, for example cable trays or wire mesh ducts,
using cable ties. Take care not to crush the cables when fastening them. Make sure there
is not too much pressure on the fiber-optic cables.
● Before laying the fiber-optic cables: Deburr the edges of the holes. Round the holes. This
prevents damage to the sheathing when you pull in and fasten the cable.
● The bending radius must not be smaller than the value specified by the manufacturer.
● The branching radii of the cable ducts must correspond to the specified bending radius for
the fiber-optic cable.
● Lay the redundancy connections so that the fiber-optic cables are securely protected from
damage.
● Always lay the two redundancy connections separately. Laying the connections
separately increases availability and protects against undefined system states. An
undefined system state occurs when the two redundancy connections are interrupted
simultaneously in a time period of ≤ 1500 ms.
Pressure
Do not exert any pressure on the cable, for example by the inappropriate use of clamps
(cable quick-mount) or cable ties.
Do not step on the fiber-optic cable.
Heat
The cables are sensitive to direct heat. Hot air guns and gas burners as used in heat-shrink
tubing must not be used on the fiber-optic cables
