Choose a coiling fiber spool according to the length of redundant fibers. Wind the fibers around the big spool first
and then the smaller spool. The fibers should not be coiled too tightly or too loosely. Ensure that the bending radius
of fibers is not less than 30 mm.
When handling optical fibers, do
not stand close to or look into the
optical fiber outlet directly with
naked eyes.
