ABSTRACT:
Disclosed is a spool for shipping low expansion optical waveguide filament. The filament supporting portion of the spool is a composite structure consisting of a cylindrically-shaped barrel of material having a thermal coefficient of expansion no greater than 125.times.10.sup.-7 /.degree.C. surrounded by a layer of resilient foam material. When a filament is wound on the spool with a predetermined tension, filament breakage and entanglement are eliminated even when the spool is subjected to temperature extremes.
