Abstract:
Chaos, a kind of noise like signals,
generated by deterministic nonlinear Dynamical system,
has good auto correlation performance. Previous
researches indicate that broad bandwidth chaos can be
easily obtained by semiconductor laser subjecting optical
feedback, optoelectronic feedback, or external optical
injection under an appropriate conditions. Break detection
for WDM-PON needed to solve the multi-branch; node
density problem for the realization of high-precision
positioning of each branch proposed a breakpoint
detection method based broadband chaotic light lasers,
with the help of powerful and elastic computation ability
and storage capacity, put proposes a framework of service
platform with a collaborative service model of hybrid cloud
in the cloud computing environment. On the basis of
analysing the characteristics of broadband chaotic
sources on a preliminary simulation results show that this
method can be highly accurate positioning WDM-PON
branch break point location, spatial resolution of 7cm and
independent of the detection distance.
