Title: Harufusa Kondo: Innovator in Optical Transmission Technology
Introduction
Harufusa Kondo is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical transmission technology, holding a total of 7 patents. His innovative work has advanced the capabilities of optical communication systems.
Latest Patents
One of Kondo's latest patents is an optical transmission device that features an optical transceiver. This device includes an optical transmitter that varies the wavelength of its output beam based on the settings of a digital to analog converter. The design incorporates beam splitters that direct two split beams into a photodetector and a wavelength filter. A quotient is calculated by dividing the digital value output from an analog to digital converter (ADC) by the digital value output from another ADC. A memory address is determined based on this quotient, allowing for the selection of a wavelength notification value from a table without compensating for the imperfect characteristics of the wavelength filter. Another notable patent is a control circuit for an optical transmitter/receiver. This circuit transmits and receives optical signals and includes a memory for storing digital values and limit values, a register, and an analog/digital conversion circuit. The circuit monitors the operating conditions of the optical transmitter/receiver and allows external access for monitoring.
