Multi-tube fiber optic cable and system and method for making the same
A multi-tube fiber optic cable maintains a plurality of fiber tubes, each fiber tube containing at least one optical fiber therein. The plurality of fiber tubes are disposed apart from a central axis of the cable. A plurality of strength members are disposed apart from a central axis of said cable. An outer jacket surrounds the plurality of fiber tubes and the plurality of strength members and is formed from a pressure extruded polymer. The plurality of fiber tubes and strength members are held in either one of an oscillated geometry or a helical geometry by the pressure extruded jacket.
1. A multi-tube fiber optic cable, said cable comprising:
a plurality of fiber tubes, each of said fiber tubes containing at least one optical fiber therein, said plurality of fiber tubes being disposed apart from a central axis of said cable;
a plurality of strength members, said strength members being disposed apart from a central axis of said cable; and
an outer pressure extruded jacket surrounding said plurality of fiber tubes and said plurality of strength members, wherein said plurality of fiber tubes and said plurality of strength members are held in either one of an oscillated geometry and a helical geometry only by said pressure extruded jacket without the use of binding tapes or yarns.
2. The multi-tube fiber optic cable as claimed in claim 1 , wherein said cable further comprises water swellable filaments disposed in close proximity to said plurality of fiber tubes.
3. The multi-tube fiber optic cable as claimed in claim 1 , wherein said strength elements are any one of glass or aramid fiber reinforced plastic rods and glass or aramid fibers.
4. The multi-tube fiber optic cable as claimed in claim 1 , wherein said outer jacket polymer is any of polyethylene (PE) and Poly vinyl chloride (PVC).
