摘要: Fiber optic distribution cables and methods for manufacturing the same are disclosed. The methods present one or more optical fibers outward of the protective covering for distribution of the same toward the subscriber. In one method of making the fiber optic distribution cables, an indexing tube is provided for indexing a tether tube within the indexing tube for providing the distribution optical fiber with a suitable excess fiber length. In another method, a demarcation point is provided for inhibiting the movement (i.e., pistoning) of the distribution optical fiber into and out of the distribution cable. In still another method, one or more caps are provided for closing one or more the openings in the protective covering used for accessing the optical fibers within the fiber optic distribution cable. Additionally, other methods may include providing a fiber optic distribution cable having a dry construction and/or a non-round cross-section.
