TABLE 6B1-I.  Equipment and materials - continued.

NOTE:        During handling, the optical fiber cable shall be protected from kinks, twists, crushing, and sharp bends.  (See Part 1 of this standard practice for more detailed optical fiber cable handling procedures.)

Step 1 - Select one end of the optical fiber cable.

Step 2 - Using the cable stripper, remove approximately 300 mm (12 in) of the outer jacket from the unterminated end of the optical fiber cable.

CAUTION: Do not cut or nick OFCC jackets.

Using the kevlar shears, carefully cut off the kevlar strength members, the exposed central member and any fillers.

Step 3 - Remove any water blocking material, clean the OFCCs with a wipe dampened with alcohol and blow them dry with air.

Step 4 - Measure and mark the OFCC cable jacket approximately 50 mm (2 in) from the end of the fiber.  Using the OFCC stripper, remove the OFCC jacket back to the mark.

Step 5 - Separate the kevlar strands from the buffered fiber and trim the strands back to the OFCC jacket end using the kevlar shears.

Step 6 - Measure and mark the buffer approximately 30 mm (1 in) from the end of the fiber.

WARNING: Wear safety glasses when removing the buffer and coating to avoid possible eye injury.

Using the buffer stripper, remove the buffer and coating back to the mark.        Remove the buffer and coating in small sections (approximately

6 mm (0.25 in)) at a time.  (NOTE:  Normally, the buffer and coating are tightly adhered to one another and come off of the fiber at the same time.)

Step 7 - Remove any residual fiber coating from the bare fiber with a wipe dampened with alcohol.  Wipe only once from the end of the buffer towards the end of the fiber.

Step 8 - Using one short light stroke with the cleaving tool, score the fiber approximately 12 mm (0.5 in) from the end of the fiber. (NOTE: Do not break the fiber with the tool.) Pull off the fiber with a gentle straight pull.  Deposit the waste fiber in a trash container.
