Abstract:
1. An optical fiber cable having a length and a longitudinal axis, said cable comprising: a longitudinal strength member disposed at said axis; a tubular plastic jacket encircling the strength member and having a circumferentially continuous outer portion, wherein the strength member and the jacket define at least one longitudinal duct between the jacket outer portion and the strength member, and wherein the jacket includes connecting portions only at circumferentially opposite sides of the duct which provide connections to the strength member; wherein said connecting portions provide connections to the strength member which resist longitudinal movement of the connecting portions with respect to the strength member when the cable is subjected to pulling forces directed parallel to the axis of the cable but which connections can be interrupted by manual forces applied to the jacket and directed radially of said axis; wherein there is at least one longitudinally extending optical fiber in the at least one duct; and wherein the optical fiber in the duct is exposed upon the interruption of the connection of the jacket to the strength member at either of the circumferentially opposite sides of the duct.
