  • Optical signal distribution network and method of converting independent optical/electrical signals
    Patent number: 5039189
    Abstract: A network for distributing a set of independent high-frequency electrical signals comprises an optical rail waveguide that is fed with a measured amount of optical power from a single source, and a set of optical railtaps positioned at sequential locations along the optical rail waveguide. Each optical railtap functions to extract a corresponding specified fraction of the measured amount of optical power from the optical rail waveguide when a corresponding one of the independent electrical signals is applied thereto. The fractions of the measured amount of optical power extracted from the optical rail waveguide at the corresponding sequential locations along the optical rail waveguide constitute a set of independent high-frequency optical signals, which correspond to the independent high-frequency electrical signals.
