Title: Innovations of Junling Xiang in Optical Network Technology
Introduction
Junling Xiang is a prominent inventor based in Chengdu, China, known for his significant contributions to optical network technology. With a total of 12 patents to his name, Xiang has been instrumental in advancing methods and devices that enhance service signal processing and data transmission in optical networks.
Latest Patents
Among his latest patents, Xiang has developed a service signal processing method and device. This method involves an optical network unit (ONU) receiving a service signal, mapping it to a flexible optical service unit frame, and sending a first passive optical network transmission convergence frame to an optical line terminal (OLT). The flexible optical service unit frame is encapsulated within the first passive optical network transmission convergence frame, allowing it to carry the service signal in both passive optical networks (PON) and optical transport networks (OTN). Notably, the ONU and OLT do not need to parse the service signal, simplifying the process.
Another significant patent involves a data processing method, an optical transmission device, and a digital processing chip aimed at improving service transmission performance. In this method, the optical transmission device compresses a to-be-transmitted data stream to create a compressed data stream. It then determines the size of a first payload area corresponding to the compressed data stream and maps it to a data frame that includes an overhead area and a payload area. The payload area consists of the first payload area, which carries a forward error correction (FEC) code, and a second payload area that carries the compressed data stream. This data frame is subsequently transmitted by the optical transmission device.
