Latest Patents

One of Yasuda's latest patents is a coherent optical reception device. This device includes a local oscillation laser that supplies laser light, a coherent optical reception front-end unit that receives a multi-level modulated optical signal, demodulates the optical signal based on the laser light, and converts the demodulated optical signal into an electrical analog signal. Additionally, it features an analog-to-digital converter that transforms the analog signal into a digital signal, a compensation unit that addresses dispersion effects, a constellation distortion compensation unit, and an error correction decoding unit.

Another notable patent is the packet transfer processing apparatus and method. This invention includes a write preference determination unit that compares the reception rate of packets from a first network with a threshold. If the reception rate exceeds this threshold, the system determines that a write operation is necessary. A write preference control unit then increases the write bandwidth for packet operations, thereby reducing the likelihood of packet loss due to bandwidth shortages.
