Title (EN) TECHNIQUES FOR INDIRECT OPTICAL COUPLING BETWEEN AN OPTICAL INPUT/OUTPUT PORT OF A SUBASSEMBLY HOUSING AND AN ARRAYED WAVEGUIDE GRATING (AWG) DEVICE DISPOSED WITHIN THE SAME
(FR) TECHNIQUES POUR COUPLAGE OPTIQUE INDIRECT ENTRE UN PORT D'ENTRÉE/SORTIE OPTIQUE D'UN BOÎTIER DE SOUS-ENSEMBLE ET UN DISPOSITIF DE PHASAR (AWG) DISPOSÉ À L'INTÉRIEUR DE CELUI-CI
Abstract:
(EN) Techniques for flexible coupling between an optical coupling receptacle/port of an optical transceiver housing and optical components within the same are disposed. In an embodiment, an optical transceiver housing includes an intermediate fiber with a first end optically coupled to an optical coupling port and a second end optically coupled to a multiplexer/de-multiplexer device, e.g., an arrayed waveguide grating (AWG) device, PLC splitter, and so on. The intermediate fiber may be routed in the transceiver housing in a manner that and the radius of the bends may be optimized to reduce fiber bending losses. The techniques herein are equally applicable to both ROSA and TOSA modules and may be utilized to achieve flexible coupling for multi-channel transceiver devices.
(FR) La présente invention concerne des techniques de couplage flexible entre un logement/port de couplage optique d'un boîtier d'émetteur-récepteur optique et des composants optiques à l'intérieur de celui-ci. Dans un mode de réalisation, un boîtier d'émetteur-récepteur optique comprend une fibre intermédiaire avec une première extrémité couplée optiquement à un port de couplage optique et une seconde extrémité couplée optiquement à un dispositif multiplexeur/démultiplexeur, par exemple un dispositif de phasar (AWG), un diviseur PLC, etc. La fibre intermédiaire peut être acheminée dans le boîtier d'émission-réception de telle sorte que le rayon des coudes puisse être optimisé pour réduire les pertes associées à la courbure de la fibre. Les techniques de l'invention sont également applicables à la fois aux modules ROSA et TOSA et peuvent être utilisées pour réaliser un couplage flexible pour des dispositifs émetteurs-récepteurs multicanaux.
