40 Gbit/s Pseudo-Linear Transmission over One Million Kilometers

Single channel 40 Gbit/s pseudo-linear (non-soliton) transmission over 1,000,000 km of TrueWave RS fiber is achieved using all-optical 2R regeneration and in-line synchronous modulation after every 400 km (4 x 1000km). Q factors greater than 19 dB are measured at several distances form 400 KM to 1,000,000 km.
