MINI-BEAM Fiber Cutting Information (unterminated plastic fibers)
Unterminated plastic fibers are designed to be cut by the customer 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:
1) Locate the “control end” of the fiber (the unfinished end). Determine the length of
fiber required for the application. Lift the top (blade) of the cutter to open the
cutting ports. Insert one of the control ends through one of the four large cutting
ports on the PFC-1 cutter so that the excess fiber protrudes from the back of the
cutter.
2) Double-check the fiber length, and close the cutter
until the fiber is cut. Using a different cutting port, cut
the second control end to the required length.
3) 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.
Do not use a cutting port more than once. The blade
may tend to dull after one cut.
MINI-BEAM Fiber Installation Information
1) If using a bifurcated fiber, first separate the two halves of the control
end of the fiber for a distance of two inches (minimum). Thread the
control ends of the fiber through the bushings (supplied with the fiber)
until they extend through about 6 mm (.25”).
2) Slide the fibers with the bushings into the ports on the face of the
MINI-BEAM until the fibers stop. Slide the bushings farther into the
ports until they seat up against the face of the MINI-BEAM. Hold the
fibers and bushings in place.
3) While holding the fibers and bushings against the face of the MINI-
BEAM, tighten the clamp screw to secure the fibers and bushings in
place.
