Latest Patents

One of Liu's latest patents is titled "Method and system for monitoring performance of optical network." This invention describes methods and systems for monitoring the performance of an optical network by marking a group of optical signals with a set of identification tags unique to network characteristics. In the preferred embodiments, fiber identification (FID) and bundle identification (BID) tags are encoded into optical signals by marking an optical signal with low-frequency dither tones. These tones have frequencies that are unique to the fiber section and to a bundle of fibers, respectively. Detecting the FID and BID tones provides more effective and accurate monitoring of the optical network's performance and allows for determining the network topology, including paths of optical channels and traffic load through different fiber sections. Other sets of hierarchically arranged identifiers encoded into optical signals have also been proposed, including identifiers related to network security and service characteristics.
