Abstract:
An optical fiber cable core comprising:a buffer tube loosely containing at least one optical fiber, said buffer tube having a longitudinal axis, a nominal outer periphery and a wall defining a bore; and at least two substantially radially incompressible, longitudinally extending strength members, each having an outer surface and a cross-sectional dimension radially of said axis less than the radial thickness of said wall, said strength members being spaced apart circumferentially of said axis and at least partially embedded in said buffer tube with portions of the surfaces of said strength members which are radially outermost with respect to said axis being spaced from said axis substantially at least as far from said axis as said nominal periphery and with buffer tube material engaging said strength members and applying coupling forces to said strength members directed radially inwardly of said strength members.
