Abstract
The invention relates to a method of winding optical fiber onto a spool. The method includes varying a target, tension applied to a fiber as the fiber accumulates onto the spool such that the percentage change in lateral load is greater than about −3.4% for each change of about 0.25″ in pack radius. The method also includes varying the target tension such that the change in lateral load per change in pack radius includes an amount greater than about −18.0 N/m . Additionally the invention includes varying the target tension applied to the optical fiber as the fiber accumulates onto the spool, such that the target tension applied to the fiber at the end of winding fiber onto the spool is at least about 0.1% or greater than the target tension at the start of winding fiber onto the spool.
