5. DETAILED REQUIREMENTS

5.l Penetration of ship structure (submarines). Optical fiber cables shall penetrate the ship structure of submarines in accordance with Figures 3Al and 3Al0 through 3A23 of MIL-STD-2003-3, as modified (see 5.5). Stuffing tube sizes for optical fiber cables shall be selected in accordance with Method 3Al-l of this standard practice.

5.2 Penetration of ship structure (surface ships) using steel or aluminum stuffing tubes. Optical fiber cables shall penetrate the ship structure of surface ships using steel or aluminum stuffing tubes in accordance with Figures 3Bl through

3B3, 3Bl0 through 3B24, 3B43 through 3B46, 3B48 and 3B49, 3Cl3 through 3Cl6 and 3Cl8 of MIL-STD-2003-3, as modified (see 5.5). Stuffing tube sizes for optical fiber cables shall be selected in accordance with Method 3Al-2 of this standard practice.

5.3 Penetration of ship structure using multiple cable penetrators (MCP's). Optical fiber cables shall penetrate the ship structure using MCP's in accordance with Figures 3B25, 3B27 through 3B35, and 3B54 through 3B66 of MIL-STD-2003-3, as modified (see 5.5). MCP insert block sizes for optical fiber cables shall be selected in accordance with Method 3Bl of this standard practice.

5.4 Penetration of ship structure using kickpipes. Optical fiber cables shall penetrate the ship structure using kickpipes in accordance with Figures 3Dl through

3D6 and 3D8 of MIL-STD-2003-3, as modified (see 5.5). Stuffing tube sizes for optical fiber cable shall be in accordance with Method 3Al-2 of this standard practice. Swage tubes may be used in place of kickpipes. Swage tube sizes for optical fiber cable shall be selected in accordance with Method 3Al-3 of this standard practice.

5.5 Retention of the watertight seal. The optical fiber cable may lose some

of its resiliency after being compressed. To ensure the watertight seal is achieved

and maintained, retighten cap (stuffing tube) or bolt (MCP) approximately 24 hours

after initial compression.
