Cabling
• No cable junction
between indoors and
outdoors.
• Easy complete installa­
tion with pre-assembled
cables.
Table 7-5 Specifications for fiber-optic cables used outdoors
Cabling
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.
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 1 dB.
