  • Patent number: 12244983
    Abstract: A PON system includes both a PON via which optical services are delivered and a wireless network overlaying the PON. The wireless network may be a self-organizing wireless mesh network, and may generally operate as a logical signaling pathway via which information regarding optical states/statuses of PON components and/or related information is delivered from the field to back-end servers of the PON system. Accordingly, the system may include multiple in-common nodes (e.g., OLTs, LMTUs, etc.) which are included in both the PON and the wireless network. Based on optical information received via the wireless network, the servers can localize the physical location of a PON fault to a particular geographical region of multiple regions serviced by the PON (in some cases narrowing the fault's physical location to a particular span, FDH, or optical terminal), and may dispatch a technician directly to the localized physical location to address the fault.

  • Patent number: 12224799
    Abstract: Provided herein are various enhanced systems, apparatuses, and techniques for optical communication among a constellation of satellites. One example includes establishing an initial cross-connect configuration comprising optical communication links among a constellation of satellites. In the initial cross-connect configuration, the satellites can optically communicate with both adjacently positioned and non-adjacently positioned satellites in the constellation. The satellites obtain angular states of the optical communication links resultant from orbital motion of the satellites. When angular states of a portion of the optical communication links reach an exclusion range, the satellites establish a subsequent cross-connect configuration to avoid optically communicating within the exclusion range.

  • Patent number: 12184341
    Abstract: The quantum communication system conveys information by exploiting quantum properties of photon streams. A photon source producing a pair of spatially separated and polarization-entangled photon streams is used. The pair collectively exist in a quantum superposition state by virtue of their mutual entanglement. An encoder establishes a modulation control signal corresponding to the information to be conveyed. An optical quantum circuit is placed in the path of one of the pair of streams, so that the first stream passes through it. The optical quantum circuit alters the quantum polarization state of the photon passing through it based on the control signal. In this way information is encoded into quantum probability distributions of the superposition state through quantum parallelism and quantum interference, whereby information is conveyed in the photon streams.
