牛年逢盛事。1997年，是我国具有重大政治、历史意义的一年：中共中央要召开15大会议，丧失主权100多年的香港回归祖国。值此盛事之年，我们《光通信技术》编辑部全体同仁怀着喜悦的心情迎来了本刊创刊20周年的喜庆日子。 Year of the Ox events. 1997 is a year that has great political and historical significance in our country. The CPC Central Committee will hold 15 major conferences and Hong Kong, which has lost more than 100 years of sovereignty, will return to the motherland. On this year of the event, all of our colleagues in the “Optical Communication Technology” Department welcomed the joyful feelings of the 20th anniversary of this magazine.
