  • Scalable DWDM network switch architecture with wavelength tunable sources
    Patent number: 6493119
    Abstract: A network switch connecting N input optical fibers and N output optical fibers, each optical fiber carrying M wavelength channels. The network switch has a control unit, a plurality of demultiplexers connected to the input output optical fibers, a plurality of tunable channel units, a switch fabric and a plurality of combiners connected to the output optical fibers. The demultiplexers and tunable channel units provide the wavelength routing function and the switch fabric, which has M×N2 switch points, switches signals from input optical fiber to output fiber so that the switch can switch signals from one wavelength channel to another and from one input optical fiber to one or more output optical fibers of the optical network. The switch fabric is formed from a plurality of switch modules, one switch module for each incoming wavelength channel.
