  • LASER POWER CONTROL USING BIAS AND MODULATION CURRENT FEEDBACK
    Publication number: 20140029635
    Abstract: Techniques are described for maintaining the extinction ratio of an output optical signal over temperature and aging. In some examples, the techniques may determine the instantaneous slope efficiency of the laser outputting the optical signal, while the laser is outputting the optical signal. Based on the determined slope efficiency, the techniques may determine the needed drive current components (e.g., at least one of the bias current and the modulation current) that results in maintaining the extinction ratio to within a desired range.

  • System for correlating a subscriber unit with a particular subscriber in a passive optical network
    Patent number: 8451979
    Abstract: A system for correlating a subscriber unit to a physical port in a point to multipoint wire line network is disclosed. An installer is prompted to manually input a location code associated with the subscriber. The location code in the subscriber unit is received, and is transmitted via the network to a central repository. The location code is stored in the central repository toward associating the location code with the physical port.
