Cisco has teamed with optical networking company Ciena to help carriers revamp their voice networks to carry data.
The companies will integrate Cisco?s 12000 Gigabit switch router (GSR) with Ciena?s optical multiplexing technology (DWDM or dense wavelength division multiplexing). This will enable telcos to build high capacity IP backbones to carry data and video services, rather than attempting to use their traditional TDM networks.
Cisco and Ciena have also set up the Optical Internetworking Forum to promote the technology among carriers. Other members include Hewlett-Packard, AT&T, Worldcom, and Sprint.
Optical internetworks are optimised to carry data. Switches and routers have integrated optical interfaces and are directly connected by fibre or optical network elements, such as DWDM. This offers data transmission speeds of up to 1Tbps.
The partners expect the first fruits of their labour to be available in two months.
