Latest Patents

One of his latest patents is a "Dispersion measurement system and method in an optical communication network." This invention relates to a system that measures dispersion in an optical fiber network. It allows for the transmission of two consecutive bursts of data at different wavelengths from a transmitting node to a receiver node. Each burst comprises a unique sequence of amplitude-modulated data, injected with a fixed known delay. This method ensures that clock recovery circuitry at the receiver node remains locked during the delay, facilitating accurate dispersion measurements without requiring an operator or additional equipment.

Another significant patent is the "Switch system and method for the monitoring of virtual optical paths in an optical burst switched (OBS) communication network." This invention provides an optical burst switch that monitors and maintains a mesh of virtual optical paths from a communication node to multiple other nodes arranged in a ring network. It enables efficient data transmission and includes a mechanism for sending data packet probes to assess the availability of physical optical paths. The system is designed to guarantee a protection switch in less than 50 ms in the event of a path failure or degradation.
