Abstract :
The theory for multilevel signal applications in digital optical-fibre communications is derived for systems with avalanche and nonavalanche photodetectors. It is shown that a multilevel signal can significantly increase the information rate and/or the repeater spacing. At the same time equaliser design can be simplified.
