8×107 Gbit/s serial WDM field trial over 500 km SSMF
01 January 2009
8 times 107 Gbit/s DWDM transmission is achieved over a 500 km field installed fibre link in the Deutsche Telekom network, indicating high link utilization of 1 bit/s/Hz spectral efficiency, needed for Terabit/s network capacity, required in a mid-term timeframe.
