MIL-STD-2042-2B(SH)

5.l.8 Locking devices for installations on submarines. Locking devices of the following method shall be used in the installation of interconnection boxes or tube routing boxes on submarines:

MIL-STD-2003-2, Figure 2A2l.

5.2 Cable entrance to equipment. Optical fiber cable entrance into equipment may employ the same devices (that is, stuffing tubes) used for electric cable entrance into equipment. When these devices are used and the procedures are the

same for both cable types, the methods will not be repeated in this standard practice. However, the methods are identified and listed here to aid the user in rapidly locating the applicable method in MIL-STD-2003. Methods unique to optical fiber cable or that differ from those for electric cable shall be in accordance with this standard practice.

5.2.l Nylon stuffing tubes. Conventional cable and BOF cable entry into spraytight, splashproof, molded plastic and watertight equipment via nylon stuffing tubes shall be in accordance with Method 2Al and Method 2Gl of this standard practice, respectively.

5.2.2 Multiple cable penetrator (MCP). Conventional cable and BOF cable entry into equipment via integral MCP's shall be in accordance with Method 2Bl and Method

2Hl of this standard practice, respectively.

5.2.3 Cable clamps. Cable entry into equipment via cable clamps shall not be permitted.

5.3 Interconnection organization.

5.3.l Conventional cable. The organization of the connectors and adapters and the shaping of the OFCCs and buffered fibers within the interconnection box shall be in accordance with Method 2Cl of this standard practice.

5.3.2 BOF cable. The forming, routing, and shaping of BOF tubes within tube routing boxes and interconnection boxes shall be in accordance with Method 2Il and Method 2I2 of this standard practice. The organization of the connectors and adapters and the shaping of the loose tube furcation cables within the interconnection box shall be in accordance with Method 2Cl of this standard practice.

5.4 Splice assembly and alignment. The interconnection of splice ferrules within the equipment shall be in accordance with Method 2Dl of this standard practice.

5.5 BOF tube furcation unit fabrication. Fabricated BOF tube furcation units shall be constructed in accordance with Method 2El of this standard practice. Other tube furcation units shall be in accordance with A-A-59729.

5.6 BOF tube furcation unit installation. BOF tube furcation units shall be used to provide a transition for BOF fibers from BOF cable to fiber optic connectors. Furcation units shall be installed in accordance with Method 2Fl of this standard practice.

5.7 BOF tube end sealing. The sealing of unused BOF tube ends shall be in accordance with Method 2Jl of this standard practice.
