Table 14- 2 Specification of fiber-optic cables for indoor applications
Cabling
Components required
Specification
The entire cabling is routed
within a building
No cable junction is required
between the indoor and
outdoor area
The necessary cable length
is available in one piece.
There is no need to connect
several cable segments by
means of distribution boxes.
Convenient and complete
installation using patch
cables
Patch cables 2 x duplex cables per system
Connector type LC–LC
Crossed cores
Further specifications you may need to observe
for your plant, e.g.:
UL approval
Halogen-free materials
Assembled patch cable Multicore cables, 4 cores per system
Connector type LC–LC
Crossed cores

cables
including patch cables for indoor applica-
tions as required
1 cable with 4 cores per fault-tolerant system
Both interfaces in one cable
1 or 2 cables with several shared cores
Separate installation of the interfaces in order to
increase availability (reduction of common
cause factor)
Connector type ST or SC, for example, to match
other components; see below
Further specifications you may need to observe
for your plant:
UL approval
Halogen-free materials
Avoid splicing cables in the field. Use prefabri-
cated cables with pulling protection/aids in whip-
lash or breakout design, including measuring
log.
Patch cable for indoor applications
Connector type LC on ST or SC, for example, to
match other components
Installation using distribution
boxes, see Fig. 12-2
One distribution/junction box per branch
Installation and patch cables are connect-
ed via the distribution box. Either ST or
SC plug-in connections can be used, for
example. Check the cross-over installa-
tion when you wire the CPUs.
