In fact they are using a techique called lambda burst switching, where each switch on the ring has a colour associated with it and when sending a packet to that switch the transmit laser retunes to that wavelenght.
It is very different than the usual OTN style DWDM transport and more like a giant ethernet switch, where every device gets 10Gbit/s uncontented transmit, that can send a packet directly to any other device, regardless of the number of devices in the ring. The number of nodes is only bound by how many lambdas you can fit in the C-band.
They are basically statistically multiplexing in the time domain.
The idea is cool but I'm not sure about the implementation.
