Abstract: Un sistema de comunicación de red óptica utiliza una red óptica pasiva coherente (PON). El sistema incluye un terminal de línea óptica (OLT) que tiene un transmisor aguas abajo y un sistema receptor aguas arriba configurado para detección coherente por división de longitud de onda de tiempo. El sistema incluye además un divisor en comunicación operativa con el OLT, y una pluralidad de unidades de red óptica (ONU) en comunicación operativa con el divisor. Cada una de la pluralidad de ONU está configurada para (i) recibir señales de ráfaga coherentes aguas abajo desde el OLT, y (ii) transmitir al menos una señal de ráfaga ascendente al OLT. El sistema receptor aguas arriba incluye además un módulo de control de potencia y un oscilador local (LO) configurado para generar una señal LO óptica. El módulo de control de potencia está configurado para controlar de forma adaptativa, en tiempo real, un nivel de potencia de la señal LO óptica.

Abstract: An optical network communication system utilizes a coherent passive optical network (PON). The system includes an optical line terminal (OLT) having a downstream transmitter and an upstream receiver system configured for time-wavelength division coherent detection. The system further includes a splitter in operable communication with the OLT, and a plurality of optical network units (ONUs) in operable communication with the splitter. Each of the plurality of ONUs is configured to (i) receive downstream coherent burst signals from the OLT, and (ii) transmit at least one upstream burst signal to the OLT. The upstream receiver system further includes a power control module and a local oscillator (LO) configured to generate an optical LO signal The power control module is configured to adaptively control, in real-time, a power level of the optical LO signal.
