Most parts of the network are based on DWDM (Dense Wavelength Division Multiplexing), and the upgrade will add support for 40G bps per wavelength using equipment from Alcatel-Lucent. Today, the network supports 10G bps.
DWDM can send several separate data connections over a single fiber using different wavelengths of light.
The whole network should be upgraded in 12 to 18 months, according to Davies. Today, the G
However, upgrading the network hasn't been as smooth as DANTE had hoped. The main problem is knowing what do you do when the network fails, including understanding why and what has failed, what to do about it and if it is possible to get a hold of spare parts, according to Davies.
Vendors typically implement the technology first and worry about manageability later, according to Davies. More emphasis on operational aspects and less on the performance would be a step in the right direction, he said.

"We ought to be able to do 40 wavelengths, but does the technology really do what is says it is going to do?" questioned Davies.
However, being an early adopter is something DANTE is comfortable with.
"I think our suppliers will learn from our experience ... we have got the time and the interest to contribute skilled personnel to help resolve these issues," said Davies.
Networking isn't just about higher speeds. DANTE is researching support for bandwidth on demand. For it to work the ability to choose when you want more bandwidth has to be supported across several different networks, which is extremely difficult to achieve, according to Davies.
DANTE is also looking at better ways to measure performance from the users point of view. A network connection that goes via G
