Title: Naoki Ainaka: Innovator in Optical Transmission Technology
Introduction
Naoki Ainaka is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of optical transmission technology, holding two patents that showcase his innovative approach to enhancing communication systems.
Latest Patents
Ainaka's latest patents include an optical transmission system and an optical transmission device. The optical transmission system is designed to transmit Wavelength Division Multiplexing (WDM) signals from a first node to a second node via optical fiber. This system features an Optical Channel Monitor (OCM) that detects the optical power of each wavelength channel at the second node. A processor controls the optical power of each wavelength channel based on the OCM's detection at the first node. Additionally, an optical circuit adjusts the optical power based on control signals from the processor. The second processor determines whether the optical powers of the wavelength channels have converged to the target level. If they have not converged, the processor controls the optical circuit using a control signal in the first cycle. Conversely, if they have converged, the processor uses a control signal in a second cycle that is longer than the first.
The optical transmission device is implemented in one of several nodes within an optical network, where different carrier frequencies are allocated to each node. This device includes a transmitter that generates subcarrier optical signals, a splitter that divides these signals, and a receiver that recovers data from the received optical signals. The difference between the carrier frequencies of adjacent nodes corresponds to the bandwidth of the subcarrier, enhancing the efficiency of data transmission.
