-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)
-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.
-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.
-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.
-Both centerpieces 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 replacement.
