DWDM :
     1. Cisco
      The Cisco ONS 15454 MSTP [Presentation ]used DWDM technique for optical communication and
also using GMPLS for network management and routing.
              Supporting up to thirty-two 2.5- or 10-Gigabit wavelengths
              Support 600 km network.
              It offer Multiservice transport platform through which SDH/SONET, Ethernet and E1
                 clients are connect through DWDM network
              I offer channel ADM (1-4 adjacent channels with same band) and also provide band
                 OADM (1 or 4 band of adjacent channels at C-band). Reconfigurable ADM also offer by
                 this product.
              Transponder for single client / Mux ponder for supporting multiple clients. It also support
                 lower-rate client (e.g. DS1/E1) over 2.5 Gbps and 10 Gbps.
              I offer 32 / 4 channel MUX & DEMUX.
              Need separate OXC.

              Cisco offer IP over DWDM solution by using carrier routers (CRS-1 4-Slot Single-Shelf
                 and Cisco XR 12404 Router ) with Cisco ONS 15454 MSTP (DWDM switch).
              Cisco also proposed S-GMPLS model which base on CRS-1 4-Slot Single-Shelf and
                 Cisco ONS 15454 MSTP (DWDM switch).
