Abstract
An IC-TROSA point-to-multipoint optical network system includes a point-to-multipoint optical network that is coupled to subscriber devices, and that is coupled to a hub device via a hub IC-TROSA device included in a hub coherent optical transceiver device coupled to the hub device. The hub IC-TROSA device includes a quadrature optical modulator subsystem, and an optical directional coupler device in the quadrature optical modulator subsystem provides a first transmit connection and a second transmit connection to the point-to-multipoint optical network. The optical directional coupler device receives first optical signals from the quadrature optical modulator subsystem and transmits them via the first transmit connection to a first subset of the subscriber devices via the point-to-multipoint optical network, and receives second optical signals from the quadrature optical modulator subsystem and transmits them via the second transmit connection to a second subset of the subscriber devices via the point-to-multipoint optical network.
