Abstract
Detailed investigations of transmission capacities of adaptively modulated
optical orthogonal frequency division multiplexed (AMOOFDM) signals against
various multimode fibre (MMF) properties, are undertaken for the first time,
based on 28000 statistically constructed impulse responses of optical amplification-free,
MMF links using intensity modulation and direct detection. The utilization
of 3-dB optical MMF bandwidths is identified to be a simple and accurate approach
for estimating, without performing complicated simulations, AMOOFDM transmission
capacities over any MMF links. For a link loss- (differential mode delay)-
dominant performance region, the estimated signal capacities have very low
relative standard deviations of $<$6% ($<$17%), which are independent of AMOOFDM modem parameters. Discussions
are also made of practical implementation of the identified approach.
