An optical spike is generated at an arbitrarily selected location within an arbitrary optical link. The optical spike is generated by deriving a spike signal having a plurality of components, and launching the spike signal into the a transmitter end of the optical link. An initial phase relationship between the components is selected such that the involved signal components will be phase aligned at the selected location. In order to achieve this operation, the initial phase relationship between the components may be selected to offset dispersion induced phase changes between the transmitter end of the link and the selected location. One or more optical spikes can be generated at respective arbitrarily selected locations within the link, and may be used for performance monitoring, system control, or other purposes.
A method of generating an optical spike at an arbitrarily selected location within an optical link, the optical spike being defined by a localized increase in peak optical intensity relative to the Root Mean Square (RMS) optical intensity, the method comprising:
A method of monitoring performance of an optical link, the method comprising steps of:
A method of controlling an arbitrarily selected one of a plurality of optical elements of an optical link, each of the plurality of optical elements being responsive to an elevated optical peak power vs. Root Mean Square (RMS) optical power, the method comprising steps of:
