40 Gbit/s OTDM soliton transmission over transoceanic distances

40 Gbit/s soliton transmission is achieved in a recirculating loop over 10000 km, for the first time to the authors' knowledge. With a single carrier wavelength. Propagation has been tested with and without polarisation multiplexing thanks to low polarisation dependency electroabsorption modulators for in-line control and for the time demultiplexing receiver.
