5. DETAILED REQUIREMENTS

5.1 Fiber optic interconnection equipment installation. The methods covered here are applicable to the fiber optic interconnection boxes and tube routing boxes. They may be extended to other fiber optic interconnection equipment only after contacting the contracting activity. The mounting of these boxes on ship structure is the same as the standard mounting methods of electrical enclosures given in MIL- STD-2003-2. These methods will not be repeated in this standard practice; however, they are identified and listed here to aid the user in rapidly locating the applicable method in MIL-STD-2003-2 to be used for installing the fiber optic interconnection box or the tube routing box. For interconnection equipment containing single mode fiber connections, shock isolation mounting methods may be required to meet system requirements. When shock isolation mounting of interconnection equipment is required, interconnection equipment mounting shall be

as specified in the installation drawings.

5.1.1 Non-watertight decks and bulkheads. The following methods shall be used to install interconnection boxes or tube routing boxes on non-watertight decks and bulkheads:

a. Steel decks and bulkheads: MIL-STD-2003-2, Figure 2A1 or 2A4.

b. Aluminum decks and bulkheads: MIL-STD-2003-2, Figure 2A6 or 2A8.

5.1.2 Watertight decks and bulkheads. The following methods shall be used to install interconnection boxes or tube routing boxes on watertight decks and bulkheads:

a. Steel decks and bulkheads: MIL-STD-2003-2, Figure 2A1 or 2A2.

b. Aluminum decks and bulkheads: MIL-STD-2003-2, Figure 2A6 or 2A7.

5.1.3 Stanchions. The following methods shall be used to install interconnection boxes or tube routing boxes on stanchions:

a. Steel stanchion: MIL-STD-2003-2, Figure 2A5.

b. Aluminum stanchion: MIL-STD-2003-2, Figure 2A9.

5.1.4 Metal joiner bulkheads. The following method shall be used to install interconnection boxes or tube routing boxes on metal joiner bulkheads:

MIL-STD-2003-2, Figure 2A11.

5.1.5 Expanded metal or wire mesh bulkhead. The following methods shall be used to install interconnection boxes or tube routing boxes on expanded metal or wire mesh bulkheads:

MIL-STD-2003-2, Figure 2A12 or 2A13.

5.1.6 Refrigerated spaces. The following method shall be used to install interconnection boxes or tube routing boxes in refrigerated spaces:

MIL-STD-2003-2, Figure 2A16.

5.1.7 GRP (glass reinforced plastic) bulkheads. The following methods shall be used to install interconnection boxes or tube routing boxes on GRP bulkheads:

MIL-STD-2003-2, Figure 2A23 or 2A24 and Figure 2A25.
