In a LMA optical fiber the index of the core region is graded and has a grading depth of \u0394ng, as measured from a central maximum at or near the axis to a lower level that is not greater than the central maximum and not less than the index of the cladding region. The brominated FR additives unexpectedly are stable at the extrusion temperatures, and provide excellent flame retardancy to the combustible polymers. A stable laser beam can be obtained to thereby improve productivity. Lacing components extend from the woven region and are used in a lacing system. The roll angle, roll rate, and stopping time are processed to generate a point on a 3D rollover plane.
