Challenges in Estimating the Information
Capacity of the Fiber-Optic Channel
Since its early
commercial deployment in the late 1980s, optical fiber has evolved
to become the predominant carrier of the globe’s communications.
Yet, after accommodating the world’s exponentially growing appetite
for transmitted data for more than three decades, its ability to
continue doing so is being challenged by fundamental factors. In
Challenges in Estimating the Information Capacity of the Fiber-Optic
Channel, these factors are reviewed and their consequences
in terms of information capacity are examined. In particular, the
difficulties that are imposed by the nonlinear nature of fiber-optic
transmission on the assessment of the capacity and on the definition
of fundamental concepts, such as bandwidth and spectral efficiency,
are reviewed.
Relevant approximations and regimes of operation in which
bounds for the capacity can be effectively assessed while covering a
broad range of applications ranging from interdatacenter
communications to links spanning transoceanic distances are
discussed. A broad variety of transmission schemes are related and the potential
benefits of spatial multiplexing with multimode and multicore fibers
are discussed.
State-of-the-art transmission experiments are also reviewed and
compared with theoretical capacity bounds. Read more at:
