Abstract: A network for distributing signals to a plurality of user having a distribution unit and a plurality of optical cables adapted to make the distribution unit communicate with the plurality of user equipment. In turn, each optical cable has an optical fibre having a core, a cladding and a predetermined simple refractive index profile ?n(r). Each optical fibre is adapted to guarantee a single-mode propagation at higher wavelengths than about 1260 nm and a few-mode propagation at about 850 nm, and each optical fibre has such refractive index profile ?n(r) as to guarantee macro-bending losses at 1550 nm that are less than about 0.5 dB and an intermodal delay ?? at 850 nm that is less than or equal to, about 1 ns/Km.
