Title: Dajiang Jin: Innovator in Optical Telecommunications
Introduction
Dajiang Jin is a prominent inventor based in Sichuan, China. He has made significant contributions to the field of optical telecommunications, holding a total of 5 patents. His work focuses on enhancing the performance monitoring of optical networks, which is crucial for the advancement of telecommunications technology.
Latest Patents
Dajiang Jin's latest patents include innovative systems designed for optical channel monitoring. One of his notable inventions is the "Optical channel monitoring using expanded-spectrum pilot tone." This system monitors the optical performance of an optical link within an optical network. It features an optical transmitter equipped with an expanded-spectrum pilot-tone modulator that modulates an expanded-spectrum pilot tone onto a high-speed data signal, generating an expanded-spectrum optical signal. The optical receiver then receives this signal and detects the pilot tone, enabling effective monitoring of the optical link's performance.
Another significant patent is the "Method and apparatus for providing a pilot tone." This invention focuses on optical telecommunications performance monitoring through a dual frequency pilot tone. By applying a dual frequency pilot tone, with one frequency selected from a low frequency band and another from a high frequency band, the system can improve wavelength channel monitoring. This method effectively reduces issues such as stimulated Raman scattering (SRS) caused crosstalk and chromatic dispersion (CD) caused pilot fading, which can adversely affect performance monitoring.
