METHOD AND DEVICE FOR ON-LINE REGENERATION OF A SIGNAL TRANSMITTED BY WAVELENGTH DIVISION MULTIPLEXED SOLITONS AND OPTICAL TELECOMMUNICATION SYSTEM COMPRISING SUCH A REGENERATING DEVICE

摘要

The invention concerns the synchronous regeneration of wavelength division multiplexed (WDM) solitons carried on an optical fibre. It consists in using lines with optical retardation, in particular light-refracting filters, upstream of the regenerators for the re-synchronisation of a subset of m soliton channels and in placing the regenerator in a position where the n-m soliton channels are naturally synchronised.
