Title: Innovations of Yoshio Hirose
Introduction
Yoshio Hirose is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of optical transmission technology, holding a total of 16 patents. His work has been instrumental in advancing communication systems and enhancing data transmission capabilities.
Latest Patents
Hirose's latest patents include an optical transmission apparatus, an optical transmission system, and an optical transmission method. The optical transmission apparatus features a wavelength variable filter that allows for variable transmission light wavelengths. It includes a receiver that captures light sent from another optical transmission apparatus, which has passed through the wavelength variable filter. Additionally, a transmitter sends a utilization permission request for a second wavelength corresponding to the first wavelength of the received light. This request is transmitted as light of the second wavelength in the form of a tone signal of a predetermined frequency. The controller then configures the wavelength of the main signal to the second wavelength upon receiving a utilization permission notification from the other optical transmission apparatus.
Another notable patent is a transmission device that includes an interface designed to acquire communication destination information from a base band unit linked to remote radio heads. This device features a receiver that receives signals of a given wavelength from optical termination devices and a transmitter that sends a first signal containing wavelength information and communication destination information to these devices. When the receiver gets a second signal of the given wavelength from an optical termination device, it establishes a relay path for communication between the base band unit and the remote radio head.
