An optical fiber cable with a plastic core having longitudinally extending plastic tubes embedded therein, each plastic tube loosely containing at least one optical fiber. The materials of the core and the tubes are selected so that there is no significant bond or link between the outer surfaces of the tubes and the core to permit easy separation of the tubes from the core. Alternatively, there may be layers of a fluid or powder intermediate the outer surfaces of the tubes and the core so that, if desired, the tubes and the core can be made of the same plastic material although, even with this structure, the tubes may be made of a plastic material different from the plastic material of the core.
