Effectiveness of the Use of 3-dB Bandwidths of Multimode Fibres for Estimating the Transmission Performance of Adaptively Modulated Optical OFDM Signals Over IMDD Links

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 am...

Description
Summary: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.
