UFC 3-580-10

Including changes 12 April 2005
Although, regional server farms are not covered by this UFC (UFC
3-580-10,) they are the first level of infrastructure that are considered critical
facilities by the NMCI Contractor (in concurrence with the NMCI Contract
administrators), and therefore only the regional server farms and NOCs are
required to comply with NFPA 75, Standard for Protection of Information
Technology Equipment.
2-4.10
Classified Network Requirements: See Paragraph 2-7 for
information.

OUTSIDE CABLE PLANT. For new construction where NMCI is
not fully implemented at a given base, see Chapter 4. This section is therefore
written describing the post cutover condition that NMCI is fully implemented as
described in the conversion process in Chapter 3.
2-5.1
Pathways. Coordinate with the NMCI Contractor to determine if
the NMCI pathways can be routed in the same ductbank with other
communication conduits. If so, external conduits (beyond the 1.5-m (5-ft) line)
and manholes are MCON/MILCON funded to the closest applicable manhole.
The location of manholes and the necessary interconnecting support structures
must be explicitly described and identified in the contract documents.
For new buildings, a minimum of one 103-mm (4-in) conduit must
be provided for NMCI service. Provide two conduits for multi-story buildings.
Three innerducts (two 41 mm (1.5 in) and one 27 mm (1 in)) are to be used in
each conduit and a pull wire is to be placed inside each of the innerducts and the
conduit. This is in addition to the conduits required for other communications
services; i.e. telephone, cable television, fire alarm and intrusion detection.
2-5.1.1
Detection. Provide electronic detection for each pathway in
accordance with the following:
Detectable warning tape above the duct back must be used for
new installations
Permanent tracer wire must be used when pulling new cable in
existing duct systems.
2-5.2
Cabling. Standard NMCI practice utilizes Single Mode (SM) fiber
optic cable, with a minimum core size of 8 microns, as the transport medium
between building EFs.
Install fiber underground in conduit.
