1. An optical fiber cable comprising:
a central strength member;
a bedding compound surrounding the central strength member;
a plurality of buffer tubes stranded around the central strength member and the bedding compound such that the bedding compound forms to the buffer tubes and defines a continuous layer between the buffer tubes and the central strength member in an inner core area;
a plurality of optical fibers inside at least one of the buffer tubes;
a jacket surrounding the plurality of buffer tubes, the jacket being an outermost layer of the optical fiber cable; and
a second bedding compound that fills interstices in an outer core area between the plurality of buffer tubes and the jacket.
