  • Optical-transmission system having a split-gain amplifier and a signal-modifying device
    Patent number: 6173094
    Abstract: An optical-transmission system includes a split-gain amplifier, a first connector device, a second connector device, and a signal-modifying device. The split-gain amplifier has a first gain stage optically connected to a first set of at least two waveguide paths and a second gain stage optically connected to a second set of at least two waveguide paths. The first connector device optically connects the at least two waveguide paths of the first set to a first combined-waveguide path. The second connector device optically connects the at least two waveguide paths of the second set to a second combined-waveguide path. The signal-modifying device is optically connected to the first and second combined-waveguide paths.
