ABSTRACT:
The present invention relates to an optical fiber cable, in particular for a distribution network, and comprising an assembly of optical fibers, wherein each of the optical fibers has a mode field diameter lying in the range 7 .mu.m to 9 .mu.m at around 1550 nm, and a cutoff wavelength less than or equal to 1.35 .mu.m, and wherein the optical fibers are assembled together in the cable by being twisted around one another or around a reinforcing element, or by being disposed lengthwise.
