CA 2290955

An optical communications apparatus, comprising: (a) at least one pump laser support, on which is located at least one pump laser which provides pump light energy suitable for one or more optical amplifiers; (b) a splitter support, on which is located an optical splitter, the splitter having at least one inlet and a plurality of outlets; and (c) at least one optical waveguide which optically connects the pump laser(s) to the inlet(s) of the optical splitter such that pump light energy transmitted from the pump laser(s) is split into a plurality of separate portions before leaving the apparatus; the pump laser support, the splitter support and the optical waveguide constituting a single discrete apparatus which is able to provide pump light energy for a plurality of optical amplifiers, each optically connected, in use, to a respective outlet of the splitter.

L'invention concerne un appareil de télécommunication optique comportant (a) au moins un support de laser de pompage, sur lequel est situé au moins un laser de pompage qui fournit de l'énergie lumineuse de pompage appropriée à un ou plusieurs amplificateurs optiques; (b) un support de dispositif de division, sur lequel se situe un dispositif de division de fibres optiques présentant au moins un orifice d'entrée et une pluralité d'orifices de sortie; et (c) au moins un guide d'ondes optiques qui connecte éventuellement le ou les laser(s) de pompage à l'orifice ou aux orifices d'entrée du dispositif de division de fibres optiques de telle manière que l'énergie lumineuse de pompage émise par le ou les laser(s) de pompage soit divisée en une pluralité de fractions distinctes avant de quitter l'appareil. Le support du laser de pompage, le support du dispositif de division de fibres optiques et le guide d'ondes optiques constituent un seul appareil distinct susceptible de fournir de l'énergie lumineuse de pompage à une pluralité d'amplificateurs optiques tous connectés par la voie optique, en cours d'utilisation, à un orifice de sortie respectif du dispositif de division.
