Title: Innovations of Atsushi Kubotera

Introduction

Atsushi Kubotera is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of telecommunications, particularly in the development of advanced multiplexing technologies. With a total of 4 patents to his name, Kubotera continues to push the boundaries of innovation in his industry.

Latest Patents

Kubotera's latest patents include a terminal multiplexer and a method of constructing the terminal multiplexer. This invention allows for upgrades to be made in response to changes in transmission systems. The terminal multiplexer is designed to work with line terminating equipment (LTE) that features both working high-speed transmission lines and protection high-speed transmission lines in a 1:1 configuration. It incorporates two sets of 10G interfaces for interfacing with high-speed transmission lines and a selection mechanism (SELH) for multiplex conversion related to low-speed transmission lines. When upgrading to an ADM adapted for 2-Fiber BLSR, the SELH unit can be replaced with a switching unit (SWH) that manages signal switching between high-speed and low-speed transmission lines. This design allows for upgrades during system operation by ensuring that signal interfaces remain consistent and that delay times between signal input and output are synchronized.

Another significant patent involves a path switching method, path switching apparatus, and nodes of UPSR. This invention features a uni-direction protection switched ring node that can switch between a working path and a protection path. It includes a failure-information detect circuit that independently detects failures on both paths. A failure-information-path identifying circuit determines the status of the paths, while a select circuit chooses the active path based on the detection results.
