Latest Patents
Calabretta holds a patent for an "Optical PON network using passive DPSK demodulation." This invention describes an optical PON network that includes a central office generating multiple DPSK modulated optical signals. The network features an optical coupling that connects these signals to at least one optical fiber. A passive distribution node, located remotely from the central office, is designed to transmit a specific wavelength of the signals to its output ports. The passive distribution node utilizes an arrayed waveguide grating to provide a passive optical connection, functioning as a bandpass filter that converts the DPSK optical signal into an intensity-modulated signal at the output port. This innovative approach enhances the efficiency and performance of optical networks.
