1. A fiber optic drop cable, comprising:
- an optical fiber;
a tight buffer layer on the optical fiber;
a plurality of strength members;
a jacket surrounding the tight buffer layer, anda coupling between the jacket and the plurality of strength members defined by partial embedment of the plurality of strength members in the jacket during extrusion, the coupling between the jacket and the plurality of strength members inhibiting transfer of tensile forces to the optical fiber;
wherein the fiber optic drop cable has an average delta attenuation of 0.4 dB or less at a reference wavelength of 1625 nanometers with the fiber optic cable wrapped 2 turns around a 7.5 millimeter diameter mandrel.

Abstract
A fiber optic drop cable includes an optical fiber, a tight buffer layer on the optical fiber, at least one strength member, and a jacket surrounding the tight buffer layer. The jacket is coupled to the at least one strength member by at least partial embedment of at least one of the strength members in the jacket, which facilitates coupling between the jacket and strength member. The fiber optic drop cable has an average delta attenuation of 0.4 dB or less at a reference wavelength of 1625 nanometers with the fiber optic cable wrapped 2 turns about a 7.5 millimeter diameter mandrel.
