Abstract :
Remotely pumped post- and preamplifiers are employed in an 80-Gb/s wavelength-division multiplexed repeaterless transmission system with a transmission distance of 352 km and a fiber loss of 65.3 dB. Low-loss silica-core fiber combined with dispersion compensation in the receiver is used to maximize the transmission distance. The eight channels which range in wavelength from 1552.30 nm to 1559.56 nm exhibit sensitivities between -31.4 dBm and -30.5 dBm for error rates of 10/sup -9/.
