Title: Qing Liu and Optical Fiber Amplifier Gain Adjustment
Introduction
Qing Liu is an inventor associated with Wuhan City, China. His patent work addresses gain adjustment in optical fiber amplifiers, a technology used in optical communications.
Latest Patents
The supplied information lists one patent for Qing Liu: “Gain Adjustment Method and Optical Fiber Amplifier.” The invention describes a control unit that determines a gain medium’s property parameter and the dynamic gain equalizer’s current attenuation spectrum. It then selects a corresponding gain-to-attenuation mapping from a preset library, identifies the attenuation spectrum for the target amplifier gain, and adjusts the equalizer to that target spectrum. This approach links amplifier gain settings with attenuation profiles to support controlled gain adjustment.
Career Highlights
The supplied career information associates Liu with Accelink Technologies Co., Ltd. and Accelink Electronic Technology Co., Ltd. His listed patent reflects work in optical amplification and signal management.
Collaborations
Liu’s listed coworker is Zhi Chen, who is identified in the supplied information as a woman. The available details do not specify her role in the patent or the nature of their collaboration.
Conclusion
Qing Liu’s listed invention focuses on coordinating an optical fiber amplifier’s target gain with the dynamic gain equalizer’s attenuation spectrum, connecting his patent record with optical communications technology.
