Abstract

A method of winding optical fiber on a bobbin comprising alternately winding in one direction around the bobbin compact and crossover layers. Each compact layer extends axially of the bobbin from a start end proximate one end of the bobbin to a finish end proximate the other end of the bobbin and includes a plurality of fiber turns in virtual axial contact with each other which define generally parallel grooves in the surface of the compact layer. The turn defining the start and finish ends of each compact layer is aligned with a respective start and finish set-back groove in the surface of the immediately preceding compact layer axially spaced from the respective start and finish ends of the preceding compact layer. Each crossover layer extends axially of the bobbin from the finish end of the preceding compact layer to proximate the start end of the preceding compact layer and includes one or more turns of fiber axially spaced from each other and disposed at an angle to the turns and grooves of the preceding compact layer.
