Title: Anthony Dunbar - Innovator in Optical Signal Technology
Introduction
Anthony Dunbar is a notable inventor based in San Jose, California. He has made significant contributions to the field of optical signal technology, particularly through his innovative patent. His work focuses on enhancing the performance and reliability of optical signal receivers.
Latest Patents
Dunbar holds a patent for an "Optical receiver decision threshold tuning apparatus and method." This invention introduces a method of controlling an optical signal receiver that utilizes three control loops. The first control loop tunes the decision threshold of the receiver when the optical network is in a substantially steady state. The second control loop rapidly switches to a reference decision threshold upon the occurrence of an alarm condition. This invention allows for rapid adjustments to compensate for optical signal changes in eye Q and received power after a protection switch or traffic reroute. Following a protection switch, a slower tuning algorithm is employed to adjust the decision threshold to a more optimum value. The third control loop incorporates a peak detector that detects the optical signal peak and a potentiometer commanded by a controller to output a commanded percentage of this peak value to adjust the threshold and respond to transients.
