This abstract first appeared for US patent application 18567525 titled 'WAVELENGTH CROSS CONNECT DEVICE, AND WAVELENGTH CROSS CONNECT METHOD
Original Abstract Submitted
A wavelength cross connect device includes: a wavelength band switching unit configured to receive wavelength multiplexed signal beams each having been transmitted in multiple bands in optical transmission lines each including one or more optical fibers, the wavelength multiplexed signal beams each including multiplexed optical signals of distinct wavelength bands, perform wavelength band conversion on each of the wavelength multiplexed signal beams so as to convert the wavelength bands of the optical signals multiplexed in the wavelength multiplexed signal beam, and output the converted wavelength multiplexed signal beams; and a WXC unit including input-side WSSes that respectively split and output the wavelength multiplexed signal beams output from the wavelength band switching unit, and output-side WSSes mesh-connected to the input-side WSSes. The WXC unit inputs the split wavelength multiplexed signal beams to the output-side WSSes while performing rerouting and outputs the rerouted wavelength multiplexed signal beams to output transmission lines.
