Nokia Siemens Networks will report on the state of the art and trends in DWDM (Dense Wavelength Division Multiplexing) technology aimed at handling the growing traffic in core networks at the WDM 2007 conference in Cannes, France taking place this week,.

Applications such as high definition TV, DVD downloads and data from Virtual Private Networks (VPN) alone will increase demand for bandwidth dramatically, the company says.

As a result, access capacity growth has to be supported by an efficient and automated high-speed core.

Today, optical backbones with a transmission speed of 40 gigabits per second are deployed. This technology is reliable and will meet bandwidth needs for the next few years. However, considering that traffic is growing by 40% a year on average, even 40 GigE networks will have to be expanded to 100 GigE.

100 GigE networks are currently the subject of standardization efforts.
