All-fiber DFB-laser-based 8-channel 100-GHz and 16-channel 50-GHz wavelength-division-multiplexing (WDM) transmitter arrays with integrated pump redundancy are demonstrated for the first time. Each fiber laser WDM channel in the modules remain in operation despite the drop out of several of the pump-diodes and the maximum power drop to each channel in an 8x8 channel 100-GHz system for the drop of seven out of eight pump diodes is just 14 dB
