Abstract

L'invention concerne des codeurs et des décodeurs permettant un codage composites de signaux de données optiques. Ces codeurs (211, 231) et décodeurs (243, 261) appliquent des sous-codes et des supercodes. Les sous-codes sont choisis de manière à présenter une durée inférieure à la durée inter-circuits ou intra circuit des supercodes. Les codeurs (211, 231) et les décodeurs (243, 261) ("codeurs") comprennent des réseaux de Bragg à fibre configurés de manière à pouvoir coder et décoder un sous-code, un supercode ou un code composite. En utilisant un codeur de sous-code et un codeur de supercode on peut reconfigurer un codeur en sélectionnant différents sous-codes et supercodes. L'invention concerne également des systèmes et des procédés de communication utilisant des codes composites.
