2.4 Strip, clean and cleave the fiber to 8 +/- 0.5 mm
(.32 ± .02 inches) measured from the end of the
900 µm buffer. Use the cleave length marker on
the assembly base to verify the length. Refer to the
notes at the beginning of this section when using
loose tube or semi-tight buffered fiber.

2.5 With the guide funnel fully forward, lay the fiber
in the central groove along the length of the fiber
holder as shown. Position it such that the stripped
and cleaved portion extends slightly beyond the tip
of the guide funnel.

and cleaved portion extends slightly beyond the tip

If the fiber has a noticeable amount of curvature,
orient it so the curvature is directed downward
toward the fiber holder. In the clamp area of the
fiber holder, place the fiber in the appropriate
groove depending on whether it is TIGHT
BUFFER, or SEMI-TIGHT BUFFER (loose tube).
