Title (EN) O-BAND OPTICAL COMMUNICATION SYSTEM WITH DISPERSION COMPENSATION
(FR) SYSTÈME DE COMMUNICATION OPTIQUE À BANDE O AVEC COMPENSATION DE DISPERSION
Abstract:
(EN) An O-band optical communication system includes a transmitter, a receiver, and an optical fiber system coupled between the transmitter and the receiver. The optical fiber system includes at least a first fiber segment, with a positive dispersion-wavelength gradient and a first zero dispersion wavelength, coupled in series to a second fiber segment, with a negative dispersion-wavelength gradient and a second zero dispersion wavelength. When an optical signal propagating along the first fiber segment has a wavelength shorter than the first zero dispersion wavelength and experiences negative dispersion, at least partial positive dispersion compensation is provided by propagation along the second fiber segment. When light of the optical signal propagating along the first fiber segment has a wavelength longer than the first zero dispersion wavelength and experiences positive dispersion, at least partial negative dispersion compensation is provided by propagation along the second fiber segment.
(FR) L'invention concerne un système de communication optique à bande O comprenant un émetteur, un récepteur et un système de fibre optique couplé entre l'émetteur et le récepteur. Le système de fibre optique comprend au moins un premier segment de fibre, avec un gradient de longueur d'onde de dispersion positive et une première longueur d'onde de dispersion nulle, couplé en série à un second segment de fibre, avec un gradient de longueur d'onde de dispersion négative et une seconde longueur d'onde de dispersion nulle. Lorsqu'un signal optique se propageant le long du premier segment de fibre a une longueur d'onde plus courte que la première longueur d'onde de dispersion nulle et subit une dispersion négative, au moins une compensation de dispersion positive partielle est fournie par propagation le long du second segment de fibre. Lorsque la lumière du signal optique se propageant le long du premier segment de fibre a une longueur d'onde plus longue que la première longueur d'onde de dispersion nulle et subit une dispersion positive, au moins une compensation de dispersion négative partielle est fournie par propagation le long du second segment de fibre.
