在国内首次研制了１０频道、１０２ｋｍ无再生中继使用１个平坦增益光纤放大器的ＷＤＭ光纤传输实验系统。每频道传输码率为１４０Ｍｂ／ｓ（２２３－１ＮＲＺＰＲＢＳ或ＣＭＩＰＲＢＳ）。系统全部采用国产ＤＦＢ激光器，它们的波长分别为１５３１ｎｍ、１５３５ｎｍ、１５３７ｎｍ、１５４５ｎｍ、１５４７ｎｍ、１５４９ｎｍ、１５５１ｎｍ、１５５９ｎｍ、１５６１ｎｍ，在波长为１５５１ｎｍ的频道内布置了２路频率间隔为１ＯＧＨｚ的频分复用（ＦＤＭ）系统。波长分布遍及整个光纤放大器的通带。１０个频道传输１０２ｋｍ后，在误码率为１×１０－９条件下，实测尚有数ｄＢ（最大为１２ｄＢ）的功率裕量。系统使用了具有１８个频道的能力且频道间隔为２ｎｍ的光栅合、分波器，作为波分复用和解复用器。
In the country for the first time developed a 10-channel, 102km without regeneration relay using a flat gain fiber amplifier WDM optical transmission experiment system. Each channel transmission bit rate of 140Mb / s (223-1NRZPRBS or CMIPRBS). All DFB lasers are used in the system. Their wavelength is 1531nm, 1535nm, 1537nm, 1545nm, 1547nm, 1549nm, 1551nm, 1559nm and 1561nm respectively. Two channels of frequency division 1OGHz are arranged in the channel of wavelength 1551nm (FDM) system. Wavelength distribution throughout the fiber amplifier passband. After 10 channels are transmitted over 102 km, a power margin of several dB (up to 12 dB) is actually measured at a bit error rate of 1 × 10 -9. The system uses a grating with 18 channel capacity and channel spacing of 2nm grating, splitter, as a wavelength division multiplexing and demultiplexer.
