Abstract
An optical fiber cable has a jacket of flame retardant and ultraviolet stabilized plastic and meets the requirements for both outdoor and indoor use. The jacket has two longitudinal portions interconnected by an intermediate longitudinal portion of a thickness less than the thickness of the two portions. One of the two portions contains a longitudinally extending strength member of sufficient tensile strength to support the cable when the cable is suspended outdoors between relatively widely spaced supports. The other of the two portions has a longitudinally extending bore which contains at least one tightly buffered, longitudinally extending optical fiber and can also contain a flexible, longitudinally extending strength member. When the cable is suspended outdoors between support, the intermediate jacket portion has sufficient strength to prevent separation of the strength member portion from the optical fiber portion. The strength member portion, when desired, can be separated from the optical fiber portion to form an optical fiber subunit, which is flexible and meets indoor riser requirements, and a strength member subunit.
