ABSTRACT:
An optical fiber payout canister (22) comprises a bobbin (30) having a dispensing end and an optical fiber pack having a plurality of optical fiber layers (34, 36) wound upon the bobbin (30). The pack has a transition winding pattern between the optical fiber layers (34, 36) at the dispensing end thereof, and an overcoat adhesive layer overlies the transition winding pattern of the optical fiber pack. The adhesive layer desirably comprises from about 80 to about 72 parts by weight of a precatalyzed organofunctional siloxane polymer and from about 20 to about 28 parts by weight of a silicone elastoplastic resin. The adhesive layer desirably has a tensile strength of from about 25 to about 40 psi, and a modulus of elasticity of from about 1200 to about 1600 psi, over a temperature range of from about -50.degree. C. to about +80.degree. C.
