摘要： Optical networks, network elements, and methods of use are described herein, including an optical network comprising head-end and tail-end network elements, an optical multiplex section (OMS) connecting the head-end and tail-end network elements, and one or more intermediate line amplifiers in the OMS between the head-end and tail-end network elements. The head-end network element may store first information indicative of a first tilt control section having the head-end and tail-end network elements as endpoints; determine information indicative of a change in topology of the OMS, such as that a first intermediate line amplifier has switched from a non-monitoring to a monitoring mode; and store second information indicative of a second tilt control section having the head-end network element and a new tail-end network element, such as the first intermediate line amplifier.

摘要： A method is described in which a coherent transmitter transmits a first optical signal having customer data through a fiber optic link. A control signal is provided to the coherent transmitter to cause the coherent transmitter to transmit a second optical signal devoid of customer data. A reflection of the second optical signal is detected via the coherent receiver. Then, a chromatic dispersion of the reflection of the second optical signal is determined and correlated with known parameters indicative of an amount of chromatic dispersion per unit length of the fiber optic link to determine a distance travelled by the second optical signal.

摘要： Disclosed herein are methods and systems for correcting power excursions. One exemplary network element may be provided with a processor; a first line port; a flexible ROADM module including a wavelength selective switch, a multiplexer, and one or more control block; a second line port; and a memory storing an orchestrator application and processor-executable instructions. Responsive to receiving a first signal indicative of an impending network state change, the processor-executable instructions cause the processor to pause all power adjustments by the control block on the flexible ROADM module and save at least one power set point value for each active passband from a first optical signal multiplexed into a second optical signal; and responsive to receiving a second signal indicative of the network state change, adjust an optical power of each active passband from the first optical signal multiplexed into the second optical signal using the power set point values.

摘要： Methods and systems for stitching real-time and historical data are disclosed herein. The data may be gathered from a line card and represent metrics of hardware or software elements of the line card. The historical data may be transferred and stored in an archive of a control card of a network element and the real-time data may be accessed by a proxy host of the control card substantially in real-time. A network administration device may access the historical data on the file collector and/or the real-time data from the proxy host of the control card and convert them to a time series database format and store the converted data in a time series database. A user may access a portion of the converted real-time and/or historical data using a graphical user interface, the accessed portion representing data gathered during a period of time selected by the user.
