Title (EN) CHANNEL EQUALIZER WITH ACOUSTO-OPTIC VARIABLE ATTENUATORS
(FR) EGALISEUR DE CANAL DOTE D"ATTENUATEURS ACOUSTO-OPTIQUES VARIABLES
Abstract: front page image
(EN)An optical communication assembly has an optical cross connect coupled to a first, a second, a third and a fourth set of optical fibers. A first demultiplexer (160) is coupled to a first input fiber and the first set of optical fibers and a second demultiplexer (168) is coupled to a second input fiber and the second set of optical fibers. A first multiplexer (162) is coupled to a first output fiber and the third set of optical fibers. A second multiplexer (170) is coupled to a second output fiber and the fourth set of optical fibers. A first set of attenuators (152) is coupled to the third set of optical fibers and a second set of attenuators(152) coupled to the fourth set of optical fibers. The attenuators may consist of acousto-optic tunable filters and are controlled by an electronic feedback loop.
(FR)L"invention concerne un assemblage de communication optique doté d"un répartiteur optique couplé à un premier, un second, un troisième et un quatrième ensemble de fibres optiques. Un premier démultiplexeur est couplé à une première fibre d"entrée et au premier ensemble de fibres optiques, tandis qu"un second démultiplexeur est couplé à une seconde fibre d"entrée et au second ensemble de fibres optiques. Un premier multiplexeur est couplé à une première fibre de sortie et au troisième ensemble de fibres optiques. Un second multiplexeur est couplé à une seconde fibre de sortie et au quatrième ensemble de fibres optiques. Un premier ensemble d"atténuateurs est couplé au troisième ensemble de fibres optiques et un second ensemble d"atténuateurs est couplé au quatrième ensemble de fibres optiques.
