Abstract
An optical fiber cable including an optical fiber ribbon in a pipe, wherein the ribbon includes at least two optical fibers arranged side by side, and wherein at least two of the optical fibers are bonded intermittently along a length of the fibers.
Claims28
A center loose tube cable, comprising:
- a central buffer pipe;
- an optical fiber ribbon disposed within the buffer pipe, the optical fiber ribbon comprising a plurality of optical fibers arranged side-by-side and bonded intermittently along a length of the fibers, wherein the optical fiber ribbon is a plurality of optical fiber ribbons, and wherein the plurality of optical fiber ribbons are not twisted together;
- a strength member;
- and
- a thermoplastic outer pipe, the thermoplastic outer pipe surrounding the central buffer pipe and the strength member.
