Abstract
Statistical models for the accumulation of crosstalk in multicore fibers
are extended to include time-varying signals and relative delays. Crosstalk
is thus described as multiple delayed copies of the signal with uncorrelated
phase. A simple model of an equalized channel suggests that independent degrees
of freedom are required to cancel each of the many delayed copies, resulting
in an unfavorable scaling of the equalizer complexity.
