Abstract
A composite bobbin (10) for use in an optical fiber canister has a surface with a spirally groove base layer (38) in which the first layer of an optical cable (42) is wound. The base layer (38) is prepared by coating the external surface of a central portion (12) of the bobbin (10) with an adhesive layer (16) of a curable two-stage epoxy, winding a tensioned wire (22) in a spiral pattern along the length of the central portion (12), and heating the bobbin (10) to cure the epoxy. The proper combination of tension and curing cycle permits the grooves of the base layer (38) to be formed to a depth of about 1/3 of the diameter of the optical cable (42).
