Cabling Necessary components Specifications
• No cable junction
between indoors and
outdoors.
• Easy complete installa
tion with pre-assembled
cables.
Installation cable for indoor
use
4-core multicore cables for the redundant system (connector type
LC-LC, cores crossed):
1 cable with 4 cores for the redundant system:
• Both interfaces in one cable
1 or 2 cables with multiple shared cores for the redundant sys
tem:
• Interfaces laid separately to increase availability (reduction of
common cause factor)
• Connector type in line with the other components

Cabling Necessary components Specifications
Installation cable for
outdoor applications (and
indoor applications)
Installation cable for outdoor use:
• 1 cable with 4 cores per S7-1500H system
Both interfaces in one cable
• 1 or 2 cables with multiple shared cores
Interfaces laid separately to increase availability (reduction of
common cause factor)
• Connector type in line with the other components
A cable junction is required
between the indoor and
outdoor area.
Installation through distri
bution boxes (patch field).
Additional information can
be found in the section
below.
Patch cable for indoors Connector type in line with the other components.
Installation of fiber-optic cables through distribution boxes (patch fields)
If cabling requires a transition from indoor to outdoor, you need to perform installation of the
fiber-optic cables via distribution boxes (patch fields). The distribution boxes (patch fields)
connect the different cables (patch and installation cables) and connector types with one
another. You need a separate distribution box (patch field) for each transition.
NOTE
The installation of connectors, distribution boxes (patch fields) and splicing of fiber-optic
cables is allowed as long as the additional attenuation does not exceed 1dB.
