ABSTRACT:
A fiber optic cable having an outer jacket, a central coaxial member and at least one buffer tube wound around the central coaxial member, the buffer tube holding at least one optical fiber, where the buffer tube is shaped to allow extensive movement of the fiber radial to the cable axis, but allows only slight movement of the fiber in other directions. The buffer tubes may be filled with a gel to cushion optical fibers within.
