Abstract: A frequency-multiplying DDS includes a digital multiplier, a phase accumulator, a post-accumulator digital processing section, and a digital-to-analog converter (DAC). The digital multiplier multiplies a digital tuning word of value M by a digital multiplier of value B, to produce a digital product (M×B), and the n-bit accumulator accumulates by a step size of the digital product (M×B), at a rate of a low-speed reference clock of frequency fCLK/B.

Abstract: Implementations described and claimed herein provide systems and methods for an optical domain controller for managing and maintaining a record of network component configuration and interconnections. The optical domain controller detects changes in a configuration of optical network elements in response to a requested service from the network, coordinates additional changes in configurations to optical network elements that may be affected by the detected change, communicates with the optical network elements to incorporate the changes to the configurations of the network element, and stores the configurations and states of the network elements. The use of the optical domain controller may thus replace or supplement a database storing network configuration information by automatically managing changes to the network as new services are instantiated directly on the optical network elements.
