Abstract

Optical network for signal transfer from a central station to subscriber stations. The signal to be distributed is split in at least two stages, with thesignal being amplified by optical amplifiers. The Erbium Doped Fiber Amplifiers (EDFAs) to be used for this purpose are fed by an optical supply signal. By building up the supply signal from various signals with wavelengths lying closely together, Stimulated Brillouin Scattering (SBS) is avoided. As a result, by utilising centrally supplied EDPAs more splitting stages may be applied, as a result of which many more subscribers may be reached from one signal source than before. The subscribers may utilise inexpensive, low-sensitivity receivers. The optical network is particularly suited to form, in conjunction with a conventional non-optical (twisted-pair) network, a hybrid bi-directional transmission system. In this connection, the optical network is intended for the distribution of wide-band signals (CATV) and the non-optical network for bi-directional transfer of narrow-band signals.
