Abstract
A transmission distance of 374 km corresponding to a fiber loss of 73. 6 dB is demonstrated in a 2.488 Gb/s repeaterless system experiment, A n improvement in the power budget of 11.0 dB is obtained from a remote ly pumped Erbium doped fiber amplifier located 66 km from the receiver , The remote EDFA provides 15.4 dB of gain with a noise figure of 5.6 dB, Furthermore, the 145-mW of pump power, which is launched into the fiber span at the receiver, gives rise to 5.3 dB of Raman gain.
