MIL-STD-2042-2B(SH)

equipment for a minimum of two reterminations. Where connectors are used for cable entrance to equipment, the cables shall be installed such that the connectors may be easily removed.

4.2.2 Cable forming and shaping. Optical Fiber Cable Components (OFCCs), loose tube furcation cables, and buffered fibers within interconnection boxes shall be routed around the inside edges of the box such that they do not block or otherwise obstruct access to any connections within the box. The group or bundle of OFCCs or loose tube furcation cables shall be protected from possible damage on sharp edges

by using ties, clamps or tubing. Care shall be taken when attaching the group or bundle as shown in the methods herein to prevent kinking or cutting the OFCC or loose tube furcation cable jackets and to ensure that bends do not violate the minimum short term bend diameter of eight times the OFCC or loose tube furcation cable OD and the minimum long term bend diameter of sixteen times the OFCC or loose tube furcation cable OD.

4.2.3 Tube forming and shaping. BOF tubes within interconnection boxes shall be routed around the inside edges of the box such that they do not block or otherwise obstruct access to any connections within the box. BOF tubes within tube routing boxes shall be routed around the inside edges of the box to the maximum extent practicable. The tubes shall be organized using ties, clamps or other

organization devices. Care shall be taken when organizing the BOF tubes as shown in the methods herein to prevent kinking or crushing the tubes and to ensure that bends do not violate the tube minimum short term and long term bend diameter of 130 mm (5 in).

4.2.4 Splice assembly and alignment. The mating and alignment of splice ferrules shall be accomplished after they enter the equipment as specified herein. The fiber optic splice ferrules shall be installed on the buffered fibers in accordance with Method 5C1 in Part 5 of this standard practice.

4.2.5 Interconnection organization. Fiber optic connectors and adapters shall be mounted on the optical patch panels mounted in the interconnection box. The position of each connector shall be in accordance with system drawings.

Unterminated fibers shall be tied off in the bundle. The reservation of unused connection spaces for unterminated fibers shall be as specified in the ship specification. If the installing activity is responsible for the internal configuration of the interconnection box, the configuration shall be in accordance with 4.2.5.1.

4.2.5.1 Connector organization. The individual patch panels shall be filled starting with the row closest to the inside of the box and working outward (see figure 2-1 for guidance). Allocated fibers [normal, alternate, and NRC fibers (see

3.23, 3.5, and 3.22) and system growth and spare fibers] shall be located nearest the inside of the box. Spare fibers (see 3.27) shall be located in close proximity to their respective allocated fibers. Unused adapters shall be located closest to the outside of the box.
