Claims29
An optical-fiber cable, comprising:
- a plurality of micromodules positioned within and surrounded by a polymeric cable jacket, one or more of said micromodules enclosing a plurality of optical fibers;
- wherein the optical-fiber cable possesses an inner cable fiber density of at least about 3.75 fibers/mm2;
- wherein one or more of said micromodules comprise polymeric material having a Young's modulus of 500 MPa or less;
- and
- wherein the optical-fiber cable possesses a cumulative micromodule filling coefficient of at least 0.5.
2 more elements
An optical-fiber cable, comprising:
- a polymeric cable jacket;
- and
- a plurality of micromodules positioned within said polymeric cable jacket, wherein said micromodules are formed from a polymeric material having a Young's modulus of less than about 300 MPa;
- wherein the optical-fiber cable possesses a cable fiber density of at least about 2.4 fibers/mm2;
- and
- wherein one or more of said micromodules possess a micromodule filling coefficient of at least about 0.5.
3 more elements
An optical-fiber cable, comprising:
- at least 720 optical fibers, each said optical fiber having an outer diameter of between about 190 microns and 210 microns;
- a plurality of micromodules, each said micromodule surrounding one or more of said optical fibers such that each of said optical fibers is positioned within one of said micromodules;
- and
- a substantially circular cable jacket surrounding said plurality of micromodules, said cable jacket having an outer diameter of about 16 millimeters or less;
- wherein one or more of said micromodules comprise polymeric material having a Young's modulus of 500 MPa or less;
- and
- wherein the optical-fiber cable possesses a cumulative micromodule filling coefficient of at least 0.6.
