Title: Kenta Hirose: Innovator in Wavelength Cross-Connect Technology

Introduction

Kenta Hirose is a prominent inventor based in Musashino, Japan. He has made significant contributions to the field of optical communication technology, particularly in wavelength cross-connect devices and methods. With a total of 2 patents, Hirose's work is at the forefront of enhancing data transmission efficiency.

Latest Patents

Hirose's latest patents include a "Wavelength Cross Connect Device" and a "Wavelength Cross Connect Method." The wavelength cross-connect device performs relay processing, allowing wavelength multiplexed signal lights, which are multiband transmitted from multiple routes, to be demultiplexed into different wavelength bands. For each route, respective optical signals of the different wavelength bands are amplified, then subject to route change by WSSs and outputted to output side routes M. The device includes C-band WXC units that match the total number of wavelength bands of the optical signals and perform relay processing on optical signals of specific wavelength bands.

Another notable patent is the "Cyclic Wavelength Band Replacement Device, Multi-Band Transmission System, and Cyclic Wavelength Band Replacement Method." This device includes as many wavelength band converters as the wavelength bands of optical signals and connects them to the output terminals of corresponding optical amplifiers. When a wavelength-multiplexed signal beam is transmitted through an optical fiber while being amplified, each wavelength band converter performs a cyclic permutation process, transitioning optical signals between different wavelength bands.
