1. :

  • A method of optical communication using a multimode fibre, the method comprising;

    using one or more optical radiation transmitters, coupling optical radiation into the multimode fibre using a launch which restricts the number of modes excited in the fibre such that background noise is suppressed in the demodulated signals, wherein the, or each, optical radiation transmitter is a single- or multi- transverse mode laser transmitter driven by a combination of modulated radio frequency signals and/or baseband signals.
