Abstract
We experimentally demonstrate the use of full-field electronic dispersion
compensation (EDC) to achieve a bit error rate of $5\times10^{- 5}$ at 22.3 dB optical signal-to-noise ratio for single-channel 10
Gbit/s on-off keyed signal after transmission over 496 km field-installed
single-mode fibre with an amplifier spacing of 124 km. This performance is
achieved by designing the EDC so as to avoid electronic amplification of the
noise content of the signal during full-field reconstruction. We also
investigate the tolerance of the system to key signal processing parameters,
and numerically demonstrate that single-channel 2160 km single mode fibre
transmission without in-line optical dispersion compensation can be achieved
using this technique with 80 km amplifier spacing and optimized system
parameters.
