Abstract :
Using an integrated laser/electroabsorption modulator transmitter, a remotely pumped postamplifier and a remotely, pumped preamplifier, a repeaterless transmission distance of 407 km over nondispersion shifted fiber is achieved at 2.5 Gbit/s. This experiment takes full advantage of high power 1480 nm pump laser diode modules through optimized remote pumping configurations and benefits from the good behavior of the electroabsorption modulator transmitted waveform in presence of fiber nonlinearity and chromatic dispersion.<>
