    摘要: The present disclosure provides dynamic performance monitoring systems and methods for optical networks to ascertain optical network health in a flexible and accurate manner. The present invention introduces accurate estimations for optical channel performance characteristics based either on existing channels or with a dynamic optical probe configured to measure characteristics on unequipped wavelengths. Advantageously, the dynamic performance monitoring systems and methods introduce the ability to determine physical layer viability in addition to logical layer viability.

    摘要: An optical network includes interconnected via an N×N WDM router. The nodes are connected to an optical waveguide ring having a duplex structure. A first set of optical waveguides connects the transmitters in the nodes and a second set of optical waveguides connects the receivers in the nodes. The N×N wavelength router is connected across the ring between the first set of optical waveguides and the second set of optical waveguides. Each of the nodes is able to communicate with any other of the nodes on a respective wavelength channel via the router.

    摘要: An optical communication system includes a head-end station, an optical fibre network and a number or sensors and actuators connected via the network to the head-end station. The head-end station includes one or more broadband sources and is arranged to output a broadband signal onto the network. The sensors modulate the broadband signal received from the head-end station and return narrowband components of the signal via the network to the head-end. There the different narrowband components are detected, for example using a demultiplexer and the resulting signals processed by control electronics. The head-end station also includes an optical circuit arranged to split a signal from a broadband source into different narrowband components. Electro-optic modulators (FOM) modulate the different narrowband components and the resulting narrowband signals are output onto the fibre network and transmitted to the actuators. The electro-optic modulators (FOM) are operated by the control electronics.
