Latest Patents

One of his latest patents is the "Optical path route design device and optical path route design method." This invention includes a transmission/reception route selection unit, a candidate selection unit, an existence judgement unit, a maximum resource 3R selection unit, and a new 3R selection unit. The design device is capable of selecting relay stations where two transmission/reception endpoints are arranged. It selects a route pair of an active system-0 route and a standby system-1 route, ensuring that these routes do not overlap. Additionally, it incorporates a backup third route that detours from the route pair via one or more relay stations, arranging a resource amount of predetermined wavelengths in a shared 3R.

Another significant patent is the "Wavelength cross connect device and wavelength cross connect method." This device includes a wavelength band switching unit that receives wavelength multiplexed signal beams transmitted in multiple bands through optical transmission lines. The unit performs wavelength band conversion on each signal beam and outputs the converted wavelength multiplexed signal beams. The WXC unit then splits and reroutes these beams to output transmission lines, enhancing the efficiency of optical communications.
