Do not look or stare into optical fibers directly without eye protection.
When routing fibers on the sides to a cabinet, bind the fibers only at the fiber-routing holes
on the back of the rotary fiber spool.
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.

WARNING
The open corrugated pipe cannot
be loaded with too many optical
fibers. A maximum of 60 fibers with
2 mm diameter are recommended
for an open corrugated pipe with 32
mm diameter.
The length for the open corrugated
pipe to enter the cabinet is about
10 cm.
