Abstract
The present invention provides an optical fiber cable having optical fibers, a buffer tube, an outer protective jacket and at least one layer of flexible strength members made of adhesive and non-adhesive yarns. The buffer tube encloses and protects the optical fibers. The at least one layer of flexible strength members made of adhesive and non-adhesive yarns adhesively connects the buffer tube to the outer protective jacket. The adhesive yarn may include a hot-melt adhesive. The at least one layer may include a single layer of three adhesive yarns and six non-adhesive yarns, arranged so that each pair of adhesive yarns has two non-adhesive yarns therebetween. The at least one layer may also include a dual layer of adhesive and non-adhesive yarns, having an inner layer of non-adhesive yarns, and an outer layer of three adhesive yarns and four non-adhesive yarns, arranged so that each pair of adhesive yarns has at least one non-adhesive yarn therebetween.
