Installing Fibers

Cutting Unterminated Plastic Fibers

Unterminated plastic fibers are designed to be cut by the user to the length required for the application.

To facilitate cutting, a Banner model PFC-1 cutting device is supplied with the fiber. Cut the fiber as follows:

Cutting Ports

Lift to Open Ports

Use small ports for fiber sizes:

• 0.25 mm (0.01 inches)

• 0.5 mm (0.02 inches)

Use large ports for fiber sizes:

• 0.75 mm (0.03 inches)

• 1.0 mm (0.04 inches)

• 1.5 mm (0.06 inches)

1. Locate the “control end” of the fiber (the unfinished end).

2. Determine the length of fiber required for the application. If using a bifurcated fiber, separate the two halves of the fiber at least 2

inches beyond the fiber cutting location.

3. Lift the top (blade) of the cutter to open the cutting ports.

4. Insert one of the control ends through one of the cutting ports on the PFC-1 cutter so that the excess fiber protrudes from the back of

the cutter.

5. Double-check the fiber length, and close the cutter until the fiber is cut.

6. Using a different cutting port, cut the second control end to the required length. To ensure a clean cut each time, do not use a cutting

port more than once.

7. Gently wipe the cut ends of the fiber with a clean, dry cloth to remove any contamination. Do not use solvents or abrasives on any

exposed optical fiber.
