Patent number: 11716150Abstract: An optical receiver capable of substantially measuring the phase and amplitude of a received intensity- or amplitude-modulated optical signal by performing digital-signal processing. In an example embodiment, a DSP of the receiver operates to reduce the detrimental effects of relative phase noise between the optical reference oscillator and optical carrier based on an optical pilot present in the received optical signal. The DSP may employ a sequence of digital filters configured to select a signal component that represents a non-vestigial modulation sideband and then perform signal equalization thereon. The signal equalization may include but is not limited to dispersion compensation. In some embodiments, the optical receiver can be a direct-detection optical receiver. In an example embodiment, the optical reference oscillator and optical carrier are generated using two respective independently running lasers that may or may not be co-located.Type: GrantFiled: March 6, 2020Date of Patent: August 1, 2023Assignee: Nokia Solutions and Networks OyInventors: Qian Hu, Robert Borkowski

Patent number: 11350191Abstract: Various example embodiments of the present disclosure relates to a physical layer, PHY, circuitry for an optical line terminal, OLT, the PHY circuitry being configured to receive a control signal including an identification of a transmitting ONT for pre-loading an equalization configuration associated with the identification of the transmitting ONT. Other example embodiments relate to a medium access control, MAC, circuitry for OLT, the MAC circuitry being configured to determine an upstream allocation map for optical network terminals, ONTs, and to generate a control signal for a PHY circuitry including synchronization information for receiving upstream optical signal bursts from a transmitting ONT and an identification of the transmitting ONT based on the upstream allocation map. Further example embodiments related to an optical line terminal, OLT, and a method therefor.Type: GrantFiled: November 12, 2020Date of Patent: May 31, 2022Assignee: Nokia Solutions and Networks OyInventors: Werner Van Hoof, Rene Bonk, Robert Borkowski

Patent number: 11265083Abstract: An apparatus for signal modulation in a point-to-multipoint optical network is configured to modulate a single-wavelength carrier wave before distribution towards optical receivers of a first type adapted for intensity detection and a second type adapted for optical field detection. The apparatus includes a first module configured to modulate the carrier wave by varying the intensity of the carrier wave to represent data intended for the first type of receivers, and by controlling the phase and/or polarization of the carrier wave during selected periods. The apparatus includes a second module configured to modulate the carrier wave by varying the phase and/or polarization of the carrier wave to represent data intended for the second type of receivers, and by varying the intensity of the carrier wave during selected periods.Type: GrantFiled: December 29, 2020Date of Patent: March 1, 2022Inventors: Jochen Maes, Robert Borkowski, Rene Bonk
