Abstract

Experimental results on repeaterless 4× 622Mb/s × 200km

2. 5Gb/s× 200km and 4. 354Gb/s （1× 2. 488Gb/s＋3 × 622Mb/s） × 160km conventional singlemode fiber transmission systems are reported in this paper. Results on another 4. 354Gb/s × 200km transmission with one repeater is also presented. Optical output from EDFA power booster is higher than 4dBm per channel （4 × 622Mb/s system）and 11dBm （2. 5Gb/s system）

respectively

while their frequency stability is better than 6 × 10-6 and 4.1× 10-6. Receiver sensitvity at the input of EDFA preamplifier reaches - 46. 8dBm （622Mb/s

NRZ 223 -1 PRBS）and - 39. sdBm （2. 5Gb/s

NRZ 223 -1 PRBS）. Bit-error rate of various channels is better than 4 × 10 12

×10-15.
