The present invention is an arrangement for utilizing optical information sent through an optical network from a sending site A to at least one receiving site, B1, B2, B3. The arrangement comprises an optical parametric amplifier OPA for receiving the optical information sent at a set of input wavelengths lambda 1 DIVIDED lambda n. The arrangement also comprises a mixer in the amplifier OPA for mixing the input wavelengths lambda 1 DIVIDED lambda n, with an optical pump wavelength lambda p and means for generating a set of optical conjugate copy wavelengths DOLLAR sim lambda 1 DIVIDED DOLLAR sim lambda n extracted from the set of input wavelengths lambda 1 DIVIDED lambda n. A WDM-splitter is used for separating the set of input wavelengths lambda 1 DIVIDED lambda n from the set of conjugate copy wavelengths DOLLAR sim lambda 1 DIVIDED DOLLAR sim lambda n. Fibers are used for forwarding the set of input wavelength and/or the set of conjugate copy wavelengths DOLLAR sim lambda 1 DIVIDED DOLLAR sim lambda n individually to the at least one of the receiving site B1, B2, B3. |
