  1. Confirm the length of fiber optic conductor lead required to create a new fiber optic cable. Cut the fiber optic conductor lead to the required length using the fiber optic cable cutter.
G11294576
  1. Open the fiber optic conductor stripper jaws and insert the fiber optic conductor lead up to the edge of the jaws.
G11294577
  1. Close the fiber optic conductor stripper jaws (1) and carefully pull the fiber optic conductor lead (2) to remove the protective casing.
G11294578
NOTE: Make sure the protective casing of the fiber optic conductor lead sits against the fiber optic conductor cutter jaw stop.
  1. Open the fiber optic conductor stripper jaws and insert the fiber optic conductor lead fully into the fiber optic conductor cutter slot. Close the fiber optic conductor stripper jaws.
G11294579
  1. Pull the fiber optic conductor core cutter lever (1) to move the cutting wheel (2) and cut the fiber optic conductor core.
NOTE: The end of the fibre optic core has now been prepared for the fitting of a brass contact.
  1. Open the fiber optic conductor stripper jaws and remove the fiber optic conductor lead.
NOTE: Make sure the fiber optic conductor core end remains clean at all times.
  1. Place fiber optic conductor stripper and fiber optic conductor lead to one side.
  1. Open the fiber optic conductor contact pliers and reposition the conductor contact locking arm to the open position.
G11294580
NOTE: Make sure the locking arm locates on the retaining pin when in the closed position.
  1. Insert a onductor contact (1) into the fiber optic conductor contact crimping jaws and reposition the conductor contact locking arm to the closed position (2).
G11294581
  1. Insert the prepared end of the fiber optic conductor lead into the conductor contact.
CAUTION: Make sure the fiber optic conductor lead is pushed in and held against the spring loaded stop when closing the fiber optic conductor contact pliers. This sets the core to the correct depth in the brass connector. Failure to follow this instruction may result in the fiber optic conductor cable malfunctioning.
  1. Push the fiber optic conductor lead fully into the conductor contact and close the fiber optic conductor contact pliers.
  1. Open the fiber optic conductor contact pliers and reposition the conductor contact locking arm to the open position.
  1. Remove the fiber optic conductor cable from fiber optic conductor contact pliers.
  1. Place fiber optic conductor contact pliers to one side.
G11294573
CAUTION: Make sure the conductor contact has been correctly fitted to the fiber optic conductor core. Failure to follow this instruction may result in the fiber optic cable malfunctioning.
NOTE:
  • The fiber optic core end must sit 0.01mm to 0.1mm below the height of the conductor contact end.
  • Make sure the fiber optic conductor contact remains clean at all times.
  1. Visually inspect the conductor contact for correct fitment to the fibre optic core.
    • Make sure the conductor contact has been visibly crimped at 4 points.
    • Pull the conductor contact by hand to make sure it is secure.
    • Make sure the end of the fiber optic core sits below the height of the new conductor contact end.
    • Fit a fiber optic conductor contact protective cap.
  1. Repeat steps 2 to 15 and fit a conductor contact to the opposite end of the fiber optic conductor cable.
  1. Measure between the conductor contact ends of the new fibre optic cable. Using a suitable tool cut a length of new protective corrugated tubing to the required length.

  1. Install the fibre optic cable into the corrugated tubing.
    1. Place the fibre optic cable inside the fiber optic conductor cable installation pliers.
    2. Insert the fiber optic conductor cable installation pliers into the corrugated tubing.
    3. Move the fiber optic conductor cable installation pliers down the length of corrugated tubing and install the fibre optic cable.
