Abstract

Fluctuations of a temporal signal propagating along long-haul transoceanic scale
fiber links can be visualised in the spatio-temporal domain drawing visual analogy
with ocean waves. Substantial overlapping of information symbols or use of multifrequency
signals leads to strong statistical deviations of local peak power from an
average signal power level. We consider long-haul optical communication systems
from this unusual angle, treating them as physical systems with a huge number of
random statistical events, including extreme value fluctuations that potentially might
affect the quality of data transmission. We apply the well-established concepts of
adaptive wavefront shaping used in imaging through turbid medium to detect the
detrimental phase modulated sequences in optical communications that can cause
extreme power outages (rare optical waves of ultra-high amplitude) during propagation
down the ultra-long fiber line. We illustrate the concept by a theoretical
analysis of rare events of high-intensity fluctuations—optical freak waves, taking
as an example an increasingly popular optical frequency division multiplexing data
format where the problem of high peak to average power ratio is the most acute.
We also show how such short living extreme value spikes in the optical data streams
are affected by nonlinearity and demonstrate the negative impact of such events on
the system performance.
