Patent ID: 8351784

Claim:
A packet-optical integrated switch, comprising: a packet line card configured to output an Ethernet packet signal to a pre-set output port, the packet signal including a destination address corresponding to the pre-set output port; a packet switch fabric configured to transfer the packet signal from the packet line card to the pre-set output port; a 10 gigabit Ethernet (10 GbE)/optical transport unit level 2 (OTU2) integrated line card configured to convert the packet signal from the packet switch fabric into an OTU2 optical signal having a pre-set wavelength and to convert an OTU2 optical signal having a pre-set wavelength into a packet signal; and a wavelength selection switch fabric including at least one port, and configured to allocate the optical signal from the 10 GbE/OTU2 integrated line card to a pre-set wavelength division multiplexing (WDM) port by pre-set wavelength to exchange the optical signal to the at least one port by wavelength; wherein the 10 GbE/OTU2 integrated line card comprises: a switch matching unit, a network processor, an interface conversion unit, and an XSBI/optical signal conversion unit, wherein the switching matching unit matches interface between the packet switch fabric and the network processor, the network processor processes and classifies data included in the packet signal from the packet switch fabric based on header information included in the packet signal, the interface conversion unit converts an interface of the network processor into a pre-set XSBI interface, and the XSBI/optical signal conversion unit converts an XSBI packet signal, a parallel signal which has passed through the interface conversion unit, into an optical signal having a pre-set wavelength.
