  • Patent number: 12176956
    Abstract: An IC-TROSA optical network system includes at least one optical network coupled to subscriber device(s) and a hub device. The hub device includes a hub coherent optical transceiver device with a hub IC-TROSA device that couples the hub device to the subscriber device(s) via the optical network(s). The hub IC-TROSA device includes an optical hybrid mixer subsystem, a first receive connection that receives first optical signals from the subscriber device(s) via the optical network(s) and provides them to the optical hybrid mixer subsystem, and a second receive connection that receives second optical signals from the subscriber device(s) via the optical network(s) and provides them to the optical hybrid mixer subsystem. The optical hybrid mixer subsystem mixes the first and second optical signals and provides mixing results for conversion to first and second electrical signals that are then transmitted to a hub signal processing subsystem.
