Abstract
Statistical investigations of the transmission performance of Adaptively
Modulated Optical Orthogonal Frequency Division Multiplexing (AMOOFDM) are
undertaken in single-channel, optical amplifier-free, Multimode Fiber (MMF)-based
links using Intensity Modulation and Direct Detection (IMDD). Numerical simulations
are performed using statistically constructed 1000 worst-case MMF links having
3-dB bandwidths varying in a range of 220–490 MHz$ \cdot$km. It is shown that, by employing practically
available devices, $>$30
Gb/s over 300-m AMOOFDM signal transmission is achievable in 99.5% of already
installed MMF links, while by employing components that may be available in
the future, the AMOOFDM technique is capable of supporting 100 Gb/s over 150-m
signal transmission in 99.5% of already installed MMF links. In addition,
it is confirmed, from a statistical point of view, that AMOOFDM has excellent
flexibility and great robustness to different types of fibers and lasers,
restricted launch conditions and practical implementation-related factors
such as optical connector offset. It is also found that cyclic prefix and
quantization are the key factors limiting the maximum achievable transmission
performance of the AMOOFDM technique.
