Abstract
A spool for optic fibers and its winding method are disclosed. The cylinder of the spool has grooves in which rods are placed during the winding operation. Thus, the circumference of the spool is greater than that of the cylinder. After winding, the rods are removed so that the winding stresses are relaxed.
