Introduction
Chan Zhao is a prominent inventor based in Shenzhen, China. He has made significant contributions to the field of optical technology, holding a total of six patents. His work focuses on methods and devices that enhance the efficiency and performance of optical signal processing.
Latest Patents
Among his latest patents are a method and device for recovering an OTUk frame, as well as a system for transporting OTUk frames. The method involves receiving an optical signal sent using a multi-lane distribution method from the OTUk frame to an interface of an optical module. It includes converting the optical signal into an electrical signal, performing electrical equalization and demodulation, and recovering multi-lane data from the demodulated signal. The data is then aligned and rearranged according to a lane sequence identifier included in an overhead frame header. This innovative approach allows for the recovery of the OTUk frame without the need for an additional training sequence overhead, thus avoiding any negative impact on system performance.
Another notable invention is a clock recovery apparatus designed to recover clock information from an input signal. This apparatus includes Fourier transforming means to convert the input signal into a frequency domain signal, correlating means to obtain a correlation value associated with a specific frequency, and clock recovery means to determine if the frequency corresponds to a clock frequency for information recovery.
