Effect of Fiber Dispersion on Broadband Chaos Communications Implemented by Electro-Optic Nonlinear Delay Phase Dynamics

In general, chaos communications involve transmitters and
receivers operating in synchronised chaotic regime located far one
from another. One should therefore overcome the dispersion effects
which considerably impede the synchronization, even for a transmission
over few kilometers of fiber links. Using broadband chaotic carrier
generated from electro-optic delayed system, I will report some
managements techniques which are currently used to get around the
dispersion in the realistic field experiments. In addition, I will
show how the time delay can be detected by a potential eavesdropper
and how dificult it becomes when high bit rate message is included.
