A simplex optical fiber cable includes an optical fiber, a buffer surrounding and in contact with the optical fiber, a layer of strength fibers disposed about the buffer, and a sheath member surrounding and in contact with the yarn layer. In cross section the cable has a diameter of less than 2.0 millimeters (mm) and thus is much smaller in diameter than optical fiber cables presently available. Preferably, if the buffer is relatively thin a slick substance is applied to the outer surface of the buffer to allow the buffer and the strength fiber layer to slide relation to each other. If the buffer is relatively thick, a friction-reducing substance can be applied to the optical fiber to facilitate stripping of the buffer from the fiber a duplex optical fiber cable includes two simplex optical fiber cables having their respective sheaths joined to produce a figure-eight configuration. A second duplex optical fiber cable includes two simplex optical fiber cables arranged side-by-side and an oversheath surrounds both cables.
