Optical communication over multimode fibres
The research project is concerned with techniques for
increasing the transmission rate of a digital data signal
over fibre-optic channels, where these use multimode fibres.
The properties of fibre-optic channels are first described,
together with suitable techniques for generating and detecting light signals.
The possible use of fibre bundles in an arrangement of a parallel data-transmission system is then investigated.
A detailed experimental investigation has been carried out
into the optical cross coupling between individual fibres
in a fibre bundle. The results of the experiment support
some theoretical predictions by other workers in this field
that there is negligible cross coupling between the individual
fibres of a fibre bundle. This suggests that it is
perfectly feasible to use a fibre bundle in a parallel
data-transmission system. However, a consideration of the
equipment complexity involved shows that this is unlikely
to lead to a cost-effective system. [Continues.
