Embodiment Construction

[0039] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same and like parts. Disclosed is a distribution cable and method of manufacture wherein one or more optical fibers of the cable are presented outside a protective layer, such as a cable jacket, for distribution. In addition, the present invention also discloses a method that can be used to manufacture a tool for distributing optical cables. In one embodiment, a relatively small opening is formed at the access location of the cable to leave a relatively small access imprint on the cable (ie, remove a small portion of the protective layer and / or other cable components). Although a relatively small opening (eg, a cable jacket breach) is formed at the access location, the method advantageously provides a length of distrib...

Abstract

Fiber optic distribution cables and methods for manufacturing the same are disclosed. The fiber optic distribution cables present one or more optical fibers outward of the protective covering for distribution of the same toward the subscriber. In one fiber optic distribution cable, a length of distribution optical fiber that is removed from the distribution cable and presented outward of the protective covering is longer than the opening at access location. In another embodiment, 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 embodiment, 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. Additionally, other embodiments may include a fiber optic distribution cable having a dry construction and / or a non-round cross-section.

Description

technical field [0001] The present invention generally relates to a fiber optic distribution cable, a method of making the fiber optic distribution cable, and tools and kits therefor. More particularly, the present invention relates to a fiber optic distribution cable for distributing fiber to subscribers in, for example, fiber to the home or street applications (FTTx), a method of manufacturing the fiber optic distribution cable, and tools and kits. Background technique [0002] Communication networks are used to transmit various signals such as voice, video, data transmission, and the like. Traditional communication networks use copper wire cables to transmit information and data. However, copper cables have disadvantages in that they are large, heavy and with reasonable cable diameters can only transmit relatively limited amounts of data. Therefore, optical cables replace most copper cables in long-distance communication network lines, thereby providing larger bandwidth...
