Title: The Innovations of Masao Tsukitani
Introduction
Masao Tsukitani is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of optical transmission systems, holding a total of 12 patents. His work focuses on improving the efficiency and performance of optical communication technologies.
Latest Patents
One of Tsukitani's latest patents is a dispersion-compensating system. This system involves a demultiplexer that separates optical signals in a specific wavelength band of 1520 nm. The demultiplexer outputs the optical signals into two branched transmission lines: the C band and the L band. A first dispersion-compensating device is placed on the common transmission line to address dispersion in both bands. Additionally, a second device is used on the L band line to further compensate for any remaining dispersion. This innovative approach allows for a significant reduction in dispersion across a wide range of signal wavelengths.
Another notable patent is related to dispersion compensating optical fibers. This fiber is designed to maintain a minimum wavelength where the actual loss value does not exceed 10 mdB/km. The fiber is particularly effective for large-capacity high-speed WDM optical transmission systems, making it a valuable asset in modern telecommunications.
