Abstract: A fiber optic cable includes a plurality of optical fiber subunits, each of the subunits including four fiber optic elements and an enclosing jacket. A plurality of optical fiber subunit assemblies are also included, each of which includes a plurality of the optical fiber subunits and an enclosing micro-sheath. The subunits are stranded around one another. A sheath encloses the plurality of optical fiber subunit assemblies.

Abstract: A loose tube fiber optic cable having at least one optical fiber, a loose tube surrounding the fiber, with the tube having an irregular inner surface. A water swellable powder is provided around the fiber and inside the tube, where the particles of the water swellable powder rest in the irregular inner surface of the tube.

Abstract: A fiber optic cable having a jacket, at least one tube and at least two fibers within the tube in a loose tube arrangement. The fibers within the tube have a fiber length differential substantially in the range of 0.01%-0.04%.

Abstract: An optical fiber cable maintains an outer jacket, at least one optical fiber tube within the jacket and for each optical fiber tube, four optical fibers, arranged in a substantially squared arrangement. The optical fibers are linearly arranged along the length of the cable. The optical fibers are loosely arranged within the fiber tube in such a manner as to allow shifting of the straight optical fibers to conform to a bending of the cable, while being simultaneously constrained such that the straight arranged fibers do not become crossed-over or overlapped during bending.

Abstract: A tight buffer optical fiber ribbon is formed from a plurality of optical fibers, each of which has a glass core, a primary coating and a second tight buffer layer. The ribbon includes first and second stand off legs, each having an inner strength core and an outer tight buffer layer. The plurality of optical fibers are coupled to one another in a substantially sequential ribbon arrangement via their tight buffer layer. The first stand off leg is attached to the substantially sequential ribbon arrangement of the optical fibers at a first end, and the second stand off leg is attached to the substantially sequential ribbon arrangement of the optical fibers at a an opposite second end.
