OPTICAL-TRANSMISSION SYSTEM HAVING A SPLIT-GAIN AMPLIFIER AND A SIGNAL-MODIFYING DEVICE

摘要

An optical-transmission system (100) includes a split-gain amplifier (300), a first connector device (50), a second connector device (60), and a signalmodifying device (400). The split-gain amplifier has a first gain stage (300a) optically connected to a first set of at least two waveguide paths (301a, 302a) and a second gain stage (300b) optically connected to a second set of at least two waveguide paths (301b, 302b). The first connector device optically connects the at least two waveguide paths of the first set to a first combinedwaveguide path (303a). The second connector device optically connects the at least two waveguide paths of the second set to a second combined-waveguide path (303b). The signal-modifying device is optically connected to the first and second combined-waveguide paths.
