摘要： In a method of synthesizing an optical signal, a multi-bit digital representation of a desired optical E-field is generated. The multi-bit digital representation has a resolution of N1-bits, where N1 is an integer greater than 2. At least two analog drive signals are synthesized based on the multi-bit digital representation. Each analog drive signal exhibits excursions between 2M discrete states (i.e. has a resolution of M-bits), where M is an integer greater than 2. An electrical-to-optical (E/O) converter is driven using the analog drive signals to generate an output optical E-field at an output of the E/O converter. An error is detected between the output optical E-field and the desired complex E-field waveform, and at least one parameter adjusted so as to minimize the detected error.

摘要： Accelerated protection switching in a multi-platform network switch may be achieved by allocating connectivity slots from the port cards to the switch cards for all states of a connection through the switch and forming maps of the allocations for use by the port cards and switch cards. By allocating connectivity slots to all states of the connection, the connection will not be blocked in connection with a state change. By storing the slot allocation in maps a connection state change may be implemented by the switch by causing traffic on the connection to be transported using the allocated slots. Various protection modes can use the same connectivity slots with collision avoidance via prepared maps Thus, having predefined paths via allocated slots provisioned through the network element enables the network element to switch very quickly from working to protection to comply with applicable standards and minimize disruption of network traffic.

摘要： 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.

摘要： Provided is an optical apparatus and method wherein power transfer coefficients arising from SRS are measured at a designated co-location point and the power of dithers, which are impressed on the channels of a multiplexed optical signal propagating through the optical apparatus, is measured at each co-location point. Within the optical apparatus distances between co-location points are short and the power transfer coefficients are effectively constant. Consequently, the power of each channel of the multiplexed optical signal at the co-location points is obtained from the power of the dithers at a respective one of the co-location points and the power transfer coefficients measured at the designated co-location point. In some embodiments, information on the channel power at the co-location points is used to provide instructions for compensating for fluctuations in channel power and/or channel count at an input and/or channel count within the optical apparatus.
