The S90R ruby scribe is a very convenient, easy-to-use tool for
scoring or cleaving fiber. It is used extensively when
connectorizing or polishing fibers. Below is a simple step-by-
step description on the most common usages for this ruby scribe.
For more detailed information on connectorization or polishing
of fibers, please refer to this pdf. Scoring is a technique for
cleaving a fiber that utilizes the ruby scribe to make a small
cut in the fiber (i.e., a score) that becomes a stress point for
cleaving. The picture to the right shows a fiber, protruding
from a connector, undergoing scoring by a ruby scribe. To score
a fiber, the cutting edge of the scribe must be held
perpendicularly to the protruding fiber. Then very lightly score
the fiber in the desired location. It will not take a lot of
force to score the fiber, and the fiber should not break during
scoring. The scribe will need only to gently touch the fiber in
order to properly score it for a clean cleave. If the fiber does
break during scoring, it m
