Abstract
A telecommunications cable including a main cable having a central buffer tube enclosed within a cable jacket and a ribbon stack positioned within the buffer tube. The main cable includes a cut region where a slot has been cut through the cable jacket and the buffer tube to provide access to the ribbon stack during manufacture of the telecommunication cable. A tether branches from the main cable at the cut region. The tether includes an optical fiber that is optically coupled to an optical fiber of the ribbon stack.
Claims9
A telecommunications cable comprising:
- a main cable including a cable jacket and a central buffer tube positioned within the cable jacket, the central buffer tube defining a buffer tube passage, the main cable also including a ribbon stack positioned within the buffer tube passage, the ribbon stack including a width, a height and a maximum cross-dimension, the buffer tube passage having a minimum cross-dimension, the main cable including a cut region where a slot has been cut through the cable jacket and the buffer tube to provide access to the ribbon stack during manufacture of the telecommunication cable, the slot having a length and a width, the width of the slot being larger than the width of the ribbon stack, and the minimum cross-dimension of the buffer tube passage being larger than the maximum cross-dimension of the ribbon stack;
- a tether that branches from the main cable at the cut region;
- an optical fiber structure that extends from the ribbon stack, through the cut region and into the tether;
- and
- an enclosure covering the cut region.

A telecommunications cable comprising:
- a main cable including a cable jacket and a central buffer tube positioned within the cable jacket, the central buffer tube defining a buffer tube passage, the main cable also including a ribbon stack positioned within the buffer tube passage, the main cable including a cut region where a slot has been cut through the cable jacket and the buffer tube to provide access to the ribbon stack during manufacture of the telecommunication cable, the ribbon stack including at least an accessed optical fiber that is accessed at the cut region;
- a tether that branches from the main cable at the cut region, the tether including a tether buffer tube surrounding at least a first optical fiber of the tether, the first optical fiber of the tether being optically coupled to the first optical fiber of the ribbon stack at a coupling location located inside an outer boundary defined by the cable jacket;
- and
- a securing structure that binds the accessed optical fiber and the first optical fiber of the tether to the ribbon stack within the buffer tube passage.
