Title: Tetsushi Nakano: Innovator in Optical Transmission Technology
Introduction
Tetsushi Nakano is a prominent inventor based in Fujisawa, Japan. He has made significant contributions to the field of optical transmission technology. With a total of 4 patents to his name, Nakano's work focuses on enhancing data transmission capabilities.
Latest Patents
One of Nakano's latest patents is an optical transmission system and optical coupler/branching filter. The objective of this invention is to create an optical transmission unit capable of coupling and branching signal lights of individual wavelengths at a data rate of 10 Gbits/s. To achieve this, dispersion compensating fibers (DCFs) are utilized, along with proper values of dispersion compensation. This allows for different characteristics depending on the respective wavelengths to be coupled, split, and passed through without being split. Additionally, the signal lights are amplified by a plurality of low-excitation optical amplifiers to regain their light levels, which may weaken due to the use of an optical coupler, branching filter, and DCF together. This innovation enables long-distance transmission of optical signals.
