Latest Patents

One of Jinghui Li's latest patents is titled "Method and apparatus for in-service optimization of the performance of an optical transmission system." This invention describes a tuning system used in a receiver of an optical transmission system. The receiver includes a data channel that transports a data signal and a monitoring channel that carries a copy of the data signal. The tuning system processes the copy of the data signal to generate a control signal that conveys tuning information. This information allows the receiver to adjust its operating point on the data channel without disturbing the actual data being transmitted.

Another notable patent is "WDM system equalization with EDFA optical amplifiers." This invention presents an in-line repeater within a Wavelength Division Multiplexed (WDM) optical fiber communication system. The repeater includes an attenuator that aids in power equalization of the WDM channels at the demultiplexer. By incorporating the attenuator, the powers and OSNR of the individual WDM channels become more uniform, reducing the time and dynamic range needed for traditional methods to equalize channel powers.
