Title: Innovations by Xiaojun Fang
Introduction
Xiaojun Fang is a prominent inventor based in Burlingame, CA (US). He has made significant contributions to the field of optical communications, holding a total of 7 patents. His work focuses on enhancing the efficiency and reliability of fiber optic transmission systems.
Latest Patents
Among his latest inventions is the "Optical Fiber Protection Switch." This innovative device comprises an optical interface and an optical switching system. The optical interface exchanges optical signals with optical fibers that are deployed in a ring configuration. The optical switching system exchanges the optical signals with the optical interface and performs ring switching of the optical signals in response to a first fault. Additionally, it performs span switching of the optical signals in response to a second fault.
Another notable patent is the "System for Reducing the Influence of Polarization Mode Dispersion in High-Speed Fiber Optic Transmission Channels." This system aims to reduce the influence of polarization mode dispersion (PMD) in high-speed fiber optical transmission channels. It encodes a signal using forward error correction (FEC) according to a specified error tolerance per codeword. The invention effectively randomizes the input polarization of the signal before transmission, thereby increasing the PMD-limited transmission distance in an optical transmission system.
