Abstract
A bobbin for holding a filament pack having a base layer wound of optical waveguide fiber. A method for winding the base layer on the bobbin base is disclosed. The optical waveguide base layer closely matches the properties of the glass and coating of the optical waveguide which makes up the filament pack. Thus, the long term stability of the filament pack is enhanced. Examples are given in which bobbins incorporating the inventive base layer were successfully unwound at high speed.
Claims8
A winding bobbin having a base for holding a wound filament pack, having a thickness and an axial dimension and having means, spaced apart and fixedly positioned on said base, of limiting the axial dimension of said filament pack, comprising:
- a wound base layer filament comprising a glass filament, coated with at least one layer of resilient material wherein the wound base layer filament is optically separated from the filament of the wound filament pack.
