Abstract :
We transmit 441 × 100 Gb/s signals in 9 THz of optical bandwidth over 9,100 km at a SE of 493% and a bitrate-distance product >400 Pb/s*km. Our 60% overhead coded modulation format achieves a 3.35 dBQ error correction threshold at an OSNR that is within 2.5 dB of the Shannon limit for the targeted SE. All channels are decoded with no errors.
