Abstract :
Transoceanic transmission at 80 Gb/s was successfully demonstrated by introducing an optical retiming, reshaping, reamplifier (3R)-signal regenerator using cross-absorption-modulation gate and self-phase-modulation-based wavelength converter. At the 3R repeater spacing of 160 km, 80-Gb/s error-free transmission over 5600 km was achieved. The power penalty at 5600 km was 2 dB, and very clear eye-opening was observed even after 11 200-km transmission.
