Title: Hiroto Ishibashi: Innovator in Optical Transceiver Technology
Introduction
Hiroto Ishibashi is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of optical transceiver technology, holding a total of 11 patents. His work focuses on improving the functionality and efficiency of optical communication systems.
Latest Patents
One of his latest patents is titled "Optical transceiver having improved functions to load control program." This invention discloses methods to load control programs into an optical transceiver that adheres to industry standards. The standard transceiver, such as SFP and/or XFP transceivers, includes control terminals in addition to a serial interface for communication with the host device. These control terminals remain inactive when the transceiver is not connected to the host device. The loader designed for this program utilizes these control terminals, allowing the optical transceiver to download the program effectively.
Another notable patent is the "Method for driving optical transmitter." This method involves controlling a laser diode (LD) by comparing its operating temperature with a predetermined transition temperature. If the operating temperature exceeds the transition temperature, the modulation current is set based on the bias current, which is independently determined by the Automatic Power Control (APC) loop. Conversely, if the operating temperature is below the transition temperature, the modulation current is determined by the operating temperature itself.
