OPTICL FIBRE FOR TO-THE-HOME DISTRIBUTION NETWORK

摘要

A network (100) for distributing signals to a plurality of user equipment (42) comprises a distribution unit (40), and a plurality of optical cables (1) adapted to make said distribution unit (40) communicate with said plurality of user equipment (42). In turn, each optical cable (1) comprises an optical fibre (10) having a core (14), a cladding (12) and a predetermined simple refractive index profile .DELTA.n(r). Each optical fibre (10) 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 .DELTA.n(r) as to guarantee macro-bending losses at 1550 nm that are less than about 0.5 dB and an intermodal delay .DELTA..tau. at 850 nm that is less than or equal to, about 1 ns/Km.
