distribution network of signals to a cultural of apparecchiatureutente.

摘要

The network uses optical fibers (10) having a difference between refractive index of core and cladding. Each optical fiber provides a single mode propagation for wavelengths greater than 1260 nm and few mode propagation for wavelength around 850 nm. The refractive index profile of the fiber provides macro-bending losses below 0.5 db at 1550 nm and an intermodal delay less than 1 ns/Km at 850 nm. Independent claims are also included for the following: (a) Optical cable; (b) Optical fiber; (c) Use of optical fiber in signal distribution network
