Abstract
This paper briefly overview recent progress on ultra high capacity optical transmission systems and relevant technologies which make these cutting-edge results happen. Steadily increase of the number of FTTH service subscribers should be one of the driving forces for higher capacity back-bone network. Among various clients, Ethernet should play a dominant role so far and in the future. Currently, 1GbE and 10GbE has widely penetrated for computer networking applications. IEEE is now targeting 100GbE as the next step after 10GbE, and intends to standardize it by 2010. So, inevitably traffic demand for back-bone network should expand further to accept 100GbE. For the time being, 43G DWDM systems have already installed for commercial services. To meet the potential demand, we are trying to develop novel ultra high capacity transmission system which can transport 100GbE clients effectively. I will briefly present some latest results of the effort toward the direction.
