MIL-STD-2042-6B(SH)

1.  SCOPE.

METHOD 6A1

VISUAL INSPECTION OF FIBER OPTIC COMPONENTS

1.1  Scope.  This method describes a procedure for a visual inspection of conventional fiber optic cables, BOF tube cables and associated FOCT components.

2.  REQUIRED EQUIPMENT AND MATERIALS.

2.1  Safety glasses are required if bare fibers are present.

3.  PROCEDURES.

3.1  Safety summary.  The following safety precautions shall be observed:

a.   Safety glasses shall be worn when handling bare fibers.

b.        Do not touch the ends of fibers as they may be razor sharp.  Wash your hands after handling bare fiber.

3.2  Procedure I. Cable inspection.

NOTE:        During handling, conventional optical fiber cable and BOF cable shall be protected from kinks, twists, crushing, and sharp bends.  (More detailed handling procedures are given in Part 1 of this standard practice.)

Step 1 - Examine the cable documentation to ensure that the optical fiber cable conforms to the requirements of MIL-PRF-85045.  Record all of the optical fiber cable information (including the manufacturer's cable identification number and any optical performance information) from

the cable documentation. (Acceptance Test only)

Step 2 - Examine the conventional optical fiber cable and BOF tube cable for the following:  (NOTE:  For optical fiber cable on a reel, examine that portion of the optical fiber cable that can be seen without removing the cable from the reel.)

a.        Damage - cuts, burnt areas, abrasions, holes, roughened areas, bulges, thin spots, kinks, or wrinkles.

b.        Marking - As a minimum, the part number, manufacturer's identification, the words "fiber optic cable", and a four-digit date code (Acceptance Test only).

c.  Color code - OFCC jacket colorations should be easily discernable

(conventional optical fiber cable only).

Step 3 - Examine the BOF fiber and BOF bundles for the following:  (NOTE:  For items on a reel, examine that portion of the item that can be seen without removing the item from the reel.)

a.        Damage - cuts, burnt areas, abrasions, holes, roughened areas, bulges, thin spots, kinks, or wrinkles.

b.        Marking - As a minimum, the part number and manufacturer's identification.
