General

1.1 This procedure describes how to access fibers in a
buffer tube in a mid-span location with or without slack
using the Corning Cable Systems OFT-000 Optical Fiber
Access Tool (OFAT) (Figure 1).
1.2 The Optical Fiber Access Tool is designed to split a
buffer tube to expose the fibers inside without damaging
them. The resulting buffer tube halves can be easily
removed with scissors.
1.3 The tool utilizes blades mounted in two precisely
machined grooves to cut the buffer tubes. The smaller
groove cuts buffer tubes 2.4 mm - 2.6 mm (0.094 -
0.102 in.) in diameter; the larger groove cuts buffer tubes
2.7 mm - 3.1 mm (0.106 - 0.122 in.) in diameter.
1.4 The OFT-000 tool is equipped with a gauge to
determine buffer tube diameter. A thumbscrew latch
facilitates cutting buffer tubes in situations where it is
difficult for the operator to grip the tool.
1.5 Both center pieces and all four outer pieces of the
OFT-000 are marked with either one or two dots to aid in
reassembling the tool after cleaning or blade replace-ment.
1.6 This issue illustrates OFT-000 tools manufactured
after February, 1993. If you are using the previous model
OFT-000 (Figure 2), please refer to issue 3 of this

2. Precautions

2.1 Safety Precautions
Safety Glasses
WARNING: The wearing of safety glasses to
protect the eyes from accidental injury is strongly
recommended when handling chemicals and cutting
fiber.
Safety Gloves
CAUTION: The wearing of safety gloves to
protect your hands from accidental injury when using sharp-
bladed tools is strongly recommended. Use extreme care when
the utility knife's blade is exposed. Dispose of used blades
2.2
Chemical Precautions
Fiber-Clean Wipes
WARNING: Contains hydrocarbons. Apply in
rooms having normal room ventilation. For prolonged
and/or repeated use, gloves are recommended. Avoid eye
contact. Keep away from open flames and ignition sources.
f ingested, do not induce vomiting. Consult a physician. If
I
contact with eyes, wash eyes with water for 15 minutes.
2.3
Buffer Tube Handling Precautions
CAUTION: Buffer tubes are sensitive to excessive
pulling, bending and crushing forces. Great care should be
exercised when handling buffer tubes. Excessive bending will
cause kinking which may damage the fibers inside.
