This paper reports the research results of three conventional single-mode optical fiber repeater transmission systems (4 × 622Mb / s) × 160km and the experimental system of 4.354Gb / s × 200km conventional single-mode optical fiber transmission. The output power of the high-stability optical transmitter with the bait fiber amplifier is respectively> 4dBm / channel (4 × 622Mb / s) and 11dBm (single channel 2.5Gb / s), the frequency stability is better than 6 × 10-6 And 4.1 × 10 -6. Four-channel optical receivers with erbium-doped preamplifiers achieve -46.8dBm (622Mb / s, NRZ223-1PRBS) and -39.5dBm (4x2.5Gb / s, NRZ223-1PRBS) sensitivity. The system bit error rate of each channel is better than 4 × 10-12 ~ 4 × 10-15.
