摘要： A heterodyne communication system uses coherent data modulation that is resistant to phase noise. In particular, a pilot tone and reference clock signal are transmitted along with the modulated data to form the basis of an electrical demodulation local oscillator at the receiver. The pilot tone and/or reference clock signal carry phase noise which is correlated with the phase noise in the data signal. At the receiver, the local oscillator is generated from the pilot tone and reference clock signal in a manner so that the local oscillator also has phase noise which is correlated with the phase noise in the data signal. Thus, the two noise components can be used to cancel each other during demodulation of the data signal using the local oscillator.

摘要： A transmitter subsystem generates an optical signal which contains multiple subbands of information. The subbands have different polarization. For example, in one approach, two or more optical transmitters generate optical signals which have different polarization. An optical combiner optically combines the optical signals into a composite optical signal for transmission across an optical fiber. In another aspect, each optical transmitter generates an optical signal containing both a lower optical sideband and an upper optical sideband (i.e., a double sideband optical signal). An optical filter selects the upper optical sideband of one optical signal and the lower optical sideband of another optical signal to produce a composite optical signal.

摘要： A menu generation system and method for use by ordinary computer users enables those users to readily construct and modify menus and submenus to execute user-prepared commands. The system comprises a program operable by such users to construct a viewable main menu with a plurality of user-defined choices thereon, and if desired a number of levels of viewable submenus, which also may have a plurality of user-selected choices thereon. The program includes various components operable by such a user for carrying certain steps or procedures. The first component is used to construct the viewable main menu, and it automatically provides at least first, second and third user-selectable choices on the main menu. The first menu choice is for creating a new menu item on the main menu. The second menu choice is for creating a new submenu. The third menu choice is for quitting the current menu. The second component is used to modify the content of the main menu and the content of any submenus as a menu item. A third component is used to create a submenu from a main menu. A fourth component is to create and modify a plurality of storage locations used by the menu generation system for storing operating commands used by the menu generation system for launching other executable programs accessible to the computer user, and for storing data that is referenced as part of creating and displaying user-viewable menus.

摘要： A frequency division multiplexing (FDM) node used in optical communications networks provides add-drop multiplexing (ADM) functionality between optical high-speed channels and electrical low-speed channels. The FDM node includes a high-speed system and an ADM crosspoint. The high-speed system converts between an optical high-speed channel and its constituent electrical low-speed channels through the use of frequency division multiplexing and preferably also QAM modulation. The ADM crosspoint couples incoming low-speed channels to outgoing low-speed channels, thus implementing the ADM functionality for the FDM node.

摘要： A device is used to wavelength lock two optical signals to some frequency offset. A photomixer section produces a frequency test signal from the beat component of the two optical signals. The frequency of the frequency test signal reflects whether the actual frequency offset of the two optical signals equals the desired offset. A frequency filter with a monotonically varying transfer function is used to filter the frequency test signal. Thus, different gains are applied to different frequencies. Comparison circuitry uses the filtered signal to determine whether the frequency filter applied the gain which corresponds to the desired frequency offset and generates a corresponding error signal.
