Patent number: 9250410Abstract: An optical fiber cable includes a jacket and modules including optical fibers. The jacket has an interior that forms an elongate conduit between proximal and distal ends. The modules extend lengthwise through the conduit without being bound together in a pattern of twisting or wound together in a pattern of stranding. Also, the jacket and modules are sized such that free space is provided within the conduit between the modules and the jacket. The jacket is at least ten meters long, and the orientation, alignment, and size of the modules allow individual modules to slide lengthwise relative to one another through the conduit. Pulling one of the modules from the proximal end of the jacket while holding the other modules fixed at the distal end of the jacket draws the one module further into the jacket on the distal end of the jacket.Type: GrantFiled: March 15, 2012Date of Patent: February 2, 2016Assignee: CORNING CABLE SYSTEMS LLCInventors: Terry L. Cooke, Christopher S. Houser, William C. Hurley, Samuel D. Navé, James M. Wilson
