Title: Kazuhiro Kunimatsu: Innovator in Transmission and Dispersion Compensation Technologies

Introduction

Kazuhiro Kunimatsu is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the fields of transmission devices and optical signal processing. With a total of eight patents to his name, Kunimatsu has established himself as a key figure in technological innovation.

Latest Patents

Among his latest patents is a transmission device and time synchronization method. This invention includes a control card and multiple IF cards. The control card receives a first set time from a host PC and calculates a second set time by adding time corresponding to one cycle of a commonly used clock signal. The control card then distributes this second set time to each of the IF cards. Once the IF cards receive the second set time, they set it in their internal timers and begin time measuring operations upon detecting a clock signal.

Another notable patent is a variable dispersion compensation device. This device features a variable dispersion compensator that subjects an input optical signal to dispersion compensation. It includes an optical receiver that converts the compensated optical signal into an electrical signal, recovers a clock signal, and outputs clock lock information. Additionally, a signal processor provides bit error rate information on the received data signal, while a controller variably adjusts the dispersion compensation value based on this information.
