A wavelength splitter is optically coupled to the other termination of the multi-fiber cable for producing light beams of different wavelengths, each illuminating the optical termination of one or more lambda-dedicated tap fibers or multi-fiber cables. From the wavelength splitter depart a number of lambda-dedicated groups of tap fibers adapted to convey the radiation to remotely arranged lambda-specific photovoltaic cells, configured for efficiently converting light energy of the specific wavelength spectrum carried along respective fiber or group of fibers into electrical energy. The lambda-specific photovoltaic cells are formed onto light spreading structures optically coupled to a respective tap fiber or multi-fiber cable, adapted to trap the injected light and convert it into electricity.

  • Publication number: 20130120008
    Abstract: PDs that can be supplied through the LAN line are discriminated from PDs that cannot be so supplied as a function of the resistance of the supply line and of the voltage drop caused by nonlinear elements in series therewith. The values of these two parameters are estimated by applying two distinct voltages to the supply terminals of the LAN line and sensing the relative steady-state currents absorbed by the power supply line, and by processing voltage and current values for estimating the resistance of the line and the voltage drop caused by nonlinear elements connected in series therewith.
