Abstract :
Using all Raman amplification with 10 dB of copropagating distributed gain, we demonstrate 25-GHz spacing transmission of 2.04 Tb/s (192 /spl times/ 10.66 Gb/s) over 30 /spl times/ 22 dB spans of TW-RS fiber. We show that all Raman amplification with substantial co-propagating distributed gain and very low launched signal power per channel into the transmission fiber is the key technology of this feasibility experiment.
