Abstract
An optical fiber assembly includes a central strength member, multiple tubes, stranded yarn, a water protection layer, reinforced strength yarns and an outer sheath. At least one of the multiple tubes has one or more optical fibers disposed within. The stranded yarn is formed around the multiple tubes and the central strength member. The water protection layer is formed around the stranded yarn. The reinforced strength yarns are formed around the water protection layer and the outer sheath is formed around the reinforced strength yarns. The optical fiber assembly has an overall diameter of less than about 11.5 mm and exhibits low strain when subjected to a tension of at least 600 pounds.
