Abstract
An optical cable is provided. The optical cable includes an outer cable body jacket and a plurality of optical fiber subunits. The optical fibers within each subunit are stranded relative to each other and are located within a thin subunit jacket. A plurality of unstranded optical fiber subunits are located within the cable jacket.
Claims16
An optical fiber cable comprising:
- an outer cable jacket;
- a first optical fiber subunit and a second optical fiber subunit surrounded by the outer cable jacket, each of the first optical fiber subunit and the second optical fiber subunit comprising:
- a subunit jacket defining a subunit passage and having a thickness of up to 1 mm;
- and
- a plurality of optical fibers arranged in an array and configured to be a rollable ribbon such that individual or groups of fiber may be folded or rolled toward other fibers in the array, the rollable ribbon located within the subunit passage;
- wherein the first optical fiber subunit and the second optical fiber subunit are not stranded within the outer cable jacket.
