"We present experimental results on transmission of 20 channels over 238 km long link composed of two spans of non zero dispersion shifted fibre. Transmission is based on distributed Raman amplification. Both spans are counter-directionally pumped by time-division-multiplexed 4 wavelengths optical units. Five of the 20 channels are 10 Gigabit Ethernet signals (10 GE). Error-free transmission has been checked with 10 GE bit error ratio tester. Experimental results are extended by numerical simulations."@en . . . "1751-8768" .
