Abstract
One embodiment of the present invention includes a router comprising an ingress edge unit with one or more ports and an egress edge unit with one or more ports connected by a switch fabric. The ingress edge unit can receive optical data and convert the optical data into a plurality of micro lambdas. The ingress edge unit can convert the incoming data to micro lambdas by generating a series of short-term parallel data bursts across multiple wavelengths. The ingress edge unit can also wavelength division multiplex and time domain multiplex each micro lambda for transmission to the switch fabric in a particular order. The switch fabric can receive the plurality of micro lambdas and route the plurality of micro lambdas to the plurality of egress edge units in a non-blocking manner.
