Abstract
By using three technologies 1 in our pioneer experiment - non-linear dispersion managed RZ transmission, distributed Raman amplification and second generation Forward Error Correcting (FEC) code, we achieved a system performance capable of achieving better than 10−15 BER. This is equivalent to 2477 kmTbit/s on true wave fiber. The span length is 100km and average span loss is 23dB. The product of span loss and number of spans (We call it OSNR tolerance) 2 is in excess of 39 dB. Both are records for a DWDM long-haul transmission system on True wave fiber and terrestrial fiber in general.
