  • Patent number: 9602218
    Abstract: Systems and methods for using a dispersion compensation circuit to directly modulate a laser. Techniques include calibrating a varactor bias point in a dispersion compensation circuit during manufacturing, but positioning the dispersion compensation circuit between a first attenuator and a second attenuator. Each attenuator, capable of reducing power of an input signal, may be adjustable so that the attenuation provided by each attenuator may be adjusted. The ratio of attenuation between attenuators may be adjusted based on either chirp of a laser or fiber length, and a varactor bias point may be adjusted by the other one of the chirp of the laser or fiber length. Thus, both chirp and fiber length may serve as a basis for adjusting attenuation between attenuators having a dispersion compensation circuit positioned between them.

  • Patent number: 8225037
    Abstract: A method and apparatus for incremental package deployment are described. In one embodiment, the method includes the redirection of disk input/output (I/O) requests to preserve contents of disk memory. Following redirection of the disk I/O request, a software distribution package is created according to disk I/O write requests redirected to unused blocks of disk memory. In one embodiment, the software distribution package is generated using a firmware agent, which uploads the software distribution package to a server, which provisions the software distribution packet to other computers within a uniform environment to ensure that each system within the uniform environment has an identical system and memory image. Other embodiments are described and claimed.

  • Patent number: 8155524
    Abstract: An improved method and apparatus is provided for transmitting a WDM optical signal. The method begins by modulating optical channels that are each located at a different wavelength from one another with (1) a respective one of a plurality of information-bearing electrical signals that all embody the same broadcast information; (2) a respective one of a plurality of RF signals having a common functional broadcast waveform, at least one of the RF signals being out of phase with respect to remaining ones of the plurality of RF signal and (3) at least one of the RF signals being phase adjusted with respect to its original phase. Each of the modulated optical channels is multiplexed to form a WDM optical signal. The WDM optical signal, while maintaining the pre-assigned phase relationships between the modulation signals of the optical channels, is forwarded onto an optical transmission path.

In one embodiment, the method includes the redirection of disk input/output (I/O) requests to preserve contents of disk memory. Following redirection of the disk I/O request, a software distribution package is created according to disk I/O write requests redirected to unused blocks of disk memory. In one embodiment, the software distribution package is generated using a firmware agent, which uploads the software distribution package to a server, which provisions the software distribution packet to other computers within a uniform environment to ensure that each system within the uniform environment has an identical system and memory image. Other embodiments are described and claimed.
