Cisco improves DWDM offerings
Cisco said that it has enhanced its Internet Protocol over dense wavelength-division multiplexing (IPoDWDM) technology.
Among those using IPoDWDM are Sprint (see accompanying story ) and Comcast.
IPoDWDM allows service providers that use Cisco’s CRS-1 Carrier Routing System to transmit data at 40 Gbps across existing 10 Gbps systems.
Cisco said it has doubled the reach of the Cisco CRS-1 40 Gbps IPoDWDM to about 1,250 miles without regeneration. The new 40 Gbps physical line module interface supports deployments in virtually any geographic area.
Meanwhile, Cisco’s XR 12000 and 12000 Series routers can now be equipped with a new 10 Gigabit Ethernet shared port adapter that enables instant bandwidth up to 10 Gbps over the same extended distance.
For its ONS 15454 platform, Cisco has developed an omnidirectional and colorless mesh reconfigurable optical add-drop multiplexer (ROADM). The company claims it will decrease truck rolls and lower the requirements for power, space and cooling by more than 50 percent.
