Bandwidth Concatenation in Multimode Fibres: A Review (Invited Paper)

The following problems are reviewed: mutual influence among imperfect joints on loss and on bandwidth; index-profile concatenation phenomena, both from a deterministic approach (i e, assuming that successive fibres can be selected on purpose) and from a statistical one (random sequences of fibres). Finally, we present previously unpublished results on WDM systems on concatenated fibres. The probability of having at least one optical channel which is severely band-width-limited is shown to be high.
