    摘要: A device may provide a signal with a first wavelength and a second wavelength to a fiber cable, and may receive an intensity change measurement of backscattered light based on the first wavelength of the signal. The device may receive a differential phase change measurement of the backscattered light based on the second wavelength of the signal, and may determine whether there is a fiber loss change, a fiber length change, and/or a fiber cut associated with the fiber cable based on the intensity change measurement. The device may determine whether there is an abnormal event associated with the fiber cable based on the differential phase change measurement, and may report one or more of the fiber loss change, the fiber length change, the fiber cut, or the abnormal event.

    摘要: A system includes a hybrid mobile network/television antenna and a routing device connected to the antenna. The hybrid mobile network/television antenna receives content via a broadcast television network and receives content via a mobile network. The routing device includes a first communication interface that connects to the hybrid mobile network/television antenna, and a second communication interface that connects to a user device and receives a request for content from the user device. The routing device selects a network from the broadcast television network or the mobile network. The first communication interface receives the requested content via the selected network, and the routing device forwards the requested content to the user device via the second communication interface.

    摘要: One or more management systems coordinate wavelength configuration patterns of a plurality of multi-wavelength optical transport nodes in an optical network for a first transport period. The one or more management systems determine data traffic demand changes in the optical network; and coordinate wavelength configuration patterns of the plurality of multi-wavelength optical transport nodes in the optical network for a second transport period, that is subsequent to the first transport period, based on the determined data traffic demand changes.

    摘要: An optical device includes a first optical port connected to a first optical fiber, and a second optical port connected to a second optical fiber. The optical device further includes first optical components that switch first optical traffic carried via a first set of optical channels from the first optical port to the second optical port, and second optical components that switch second optical traffic carried via a second set of optical channels from the second optical port to the first optical port. The second set of optical channels includes different optical channels than the first set of optical channels. The optical device also includes a receiver that coherently detects portions of the first optical traffic and the second optical traffic, and converts the detected portions of the first and second optical traffic to electrical signals for delivery to a node or network external to the optical device.

    摘要: A network management device monitors an optical network that is configured for a required bandwidth. The optical network includes multiple optical nodes and a plurality of light paths between the multiple optical nodes. The multiple optical nodes include transport cards with a majority of the transport cards provisioned as active cards to receive a traffic load of up to full capacity of the transport cards, and with a minority of the transport cards provisioned as floating spare cards for the active cards. The network management device identifies an unused first floating spare card and an unused second floating spare card in a pair of the multiple optical nodes and automatically provisions, by the network management device, the first floating spare card and the second floating spare card to service a light path for best-effort traffic between the pair of the multiple optical nodes.

    摘要: A transport management system receives a request for a planned interruption in an optical network, and identifies transport equipment of the optical network affected by the planned interruption. The transport management system selectively sends a notification, from the network device, the identified transport equipment affected by the planned interruption, including a scheduled time of the planned interruption and a duration associated with the planned interruption, where the notification enables the notified transport equipment to buffer data to be transmitted on links affected by the planned interruption for the notified duration of the planned interruption.

    摘要: A desired characteristic associated with a signal generated by a programmable transmitter is determined. The signal may be combined with other signals to form a combined signal, and sub-optical monitoring may be performed on the combined signal to determine an optical characteristic associated with the signal. The optical characteristic may be evaluated to determine if the programmable transmitter is operating improperly. For example, if the optical characteristic does not conform to a desired range of values, it is determined whether the optical characteristic is intentionally set outside of the desired range. A tuning instruction to reconfigure the programmable transmitter may be generated if the programmable transmitter is operating improperly.
