TELECOMMUNICATION SYSTEMS. The purpose of this section is to
provide requirements for Base Level Information Infrastructure (BLII) Pier Connectivity
Specifications, telephone service, and other telecommunications systems.
3-9.1
BLII Pier Connectivity. These guidelines are provided for planning,
designing, engineering, and constructing new or repairing existing Navy piers. Figure 3-
19 illustrates the three major components that are required to provide end-to-end
connectivity to IT-21 compatible ships. They are the Pier Head ITN Building Node; the
Pier Fiber Distribution Center, and the Fiber Optic Riser Panels.
3-9.1.1
Pier Head ITN Building Node. The Pier Head ITN Building Node is
connected to the Base Area Network (BAN) and becomes the interface for adding
additional piers to the infrastructure for SIPRNET/NIPRNET connectivity. At the time
this document was prepared, Pier Head ITN Building Nodes have been installed or are
in the process of being installed at the following activities: Naval Station Mayport,
Submarine Base Kings Bay, Weapons Station Earle, Submarine Base New London,
Naval Station Little Creek, and Naval Station Norfolk. Other stations will be added as
the Navy Marine Corps Internet (NMCI) comes on line. A 144-strand hybrid fiber optic
cable (72 multi mode and 72 single mode) is required between the Pier Head ITN
Building Node and the Pier Fiber Distribution Center. This cable may already exist if the
pier is being repaired; however, for new pier construction, the cable will need to be
installed. The designer should coordinate with the local Information Technology (IT)
group to ensure that the proper Pier Head ITN Building Node has been identified. All
cabling and interconnections inside the Pier Head ITN Building Node are the
responsibility of the local IT group unless other prior arrangements have been made.
3-9.1.2
Pier Fiber Distribution Center. The Pier Fiber Distribution Center
provides a breakout point for the 144-strand hybrid fiber optic cable coming from the
Pier Head ITN Building Node and the Fiber Optic Riser Panels. Figure 3-20 shows the
fiber optic cable entering into the splice can from the Pier Head ITN Building Node. The
fiber is spliced onto another 144-strand fiber optic cable (72MM/72SM) for submarine
piers or 96-strand fiber optic cable (48MM/48SM) for surface ship piers. This is routed
to the Environmental Distribution Center 1 (EDC 1) patch panel. Using internal patch
cables, EDC 1 is patched to EDC 2. From EDC 2, a 144 or 96 strand hybrid fiber optic
cable is routed to a second splice can where it is spliced to several 24-strand hybrid
fiber optic cables (12MM/12SM) that run to the Fiber Optic Riser Panels. Figures 3-21
through 3-24 provide detailed information on the EDC 1 and EDC 2 patch panels
located inside the Pier Fiber Distribution Center and their interconnections (note that the
patch panels are shown for both surface ship piers and submarine piers).
3-9.1.3
Fiber Optic Riser Panel. The Fiber Optic Riser Panel is the interface for
the ship to shore connectivity. The panel is provided with a 24-strand hybrid fiber optic
cable (12MM/12SM) coming from the Pier Fiber Distribution Center. This provides a
fiber optic receptacle, J1, to interface with the umbilical cable assembly that goes to the
