Abstract

The feasibility of using multimode fibre as an inexpensive cell feed in broadband indoor picocellular systems is investigated. The performance of coded orthogonal frequency division multiplexing for a variety of multimode fibre profiles, including stepped index and α-profile graded index fibres is assessed. In addition to its ability to perform well in a frequency selective multipath environment, OFDM is shown to offer good protection against the frequency selectivity of a dispersive multimode fibre. Data-rates in excess of 100 Mb/s (without equalisation) over a multimode fibre channel are possible, whereas they may be limited to some 20-30 Mb/s using conventional ASK modulation
