Including changes 12 April 2005
with the NMCI Contractor as a requirement of the contract. Provide access to all
pathways for the installation of additional cabling over the life of the building.
A common pathway approach utilizes complete conduit home runs
from the work area to the TR. Size cable trays, when used, per ANSI / TIA / EIA
569-A. Where conduit is utilized, stub a minimum of one 27-mm (1-in) conduit
per drop up in the ceiling. Another pathway option for unclassified services
consists of cable run from the TR along cable tray and J-hooks suspended above
a plenum ceiling, using the "streets and alleys" design approach, dropping
through interior walls or support columns in conduit, and terminating at the wall
outlet

Cable
2-6.2.1
Backbone Cable. Provide fiber backbone cable. Coordinate
backbone requirements with NMCI contractor. On bases with low capacity POP
equipment (less than 50 seats), the NMCI Contractor may require copper
interconnect cabling to be used between the ER and TR. Add additional
backbone as required to support legacy networks.
2-6.2.2
Horizontal Cable. Provide home run cabling from each work area
to the nearest telecommunications room consisting of Category 5e UTP cable.
Terminate network and voice drops on eight-position 8-conductor Category 5e
jacks, wired to the T568A configuration. Provide plenum rated cable as required
by NFPA 70 or authority having jurisdiction.
2-6.3
Jacks and Cover Plates. For work area outlets, provide a 1 Voice
+ 1 Data (1V+1D) configuration contained in a single quad-4 position faceplate or
wall plate. A typical wall plate configuration is shown in Figure 2-3. Cover
positions 2 and 4 with blanks. Provide additional data outlet to support legacy or
special voice and data systems when required.
2-6.3.1
Fiber to the Desktop. If mission requirements for the work area
include data rates above Category 5e (100 Base T), specific security
requirements, or specific environmental constraints, then fiber optic cable to the
desktop may be supported. The specific requirements must be authorized and
must be identified by individual line items in the EFD 1391. A fiber optic home
run is not supported by the standard NMCI contract seat. If fiber to the desktop
is required, the NMCI monthly seat cost may therefore be significantly higher and
would need to be identified under a separate NMCI CLIN.
2-6.3.2
Category 6 (CAT 6) Cabling. Category 6 cable has been
approved in ANSI / TIA / EIA 568-B.2-1. Analogous to fiber optic, CAT 6 is not
supported under the current NMCI contract. At this time it is not known if there
will be additional costs associated with CAT 6 cable and therefore, the DoN has
not converted to CAT 6.
