ABSTRACT:
In general, in one aspect, the disclosure describes a multi-stage switch having a plurality of ingress switching modules to receive data and to generate frames that are transmitted as a wavelength division multiplexed signal. The multi-stage switch further includes a core switching module operatively connected to receive the wavelength division multiplexed signal from the at least one ingress switch module and to switch the frames. The multi-stage switch additionally includes a plurality of egress switching modules to receive the wavelength division multiplexed signal from the core switch module and to transmit data. The multi-stage switch is capable of detecting faulty paths and transmitting data through fault-free paths.
