摘　　要：OTDM(光时分复用 )利用光脉冲的合成技术 ,可以突破电子瓶颈的限制使通信系统的单信道速率达到数百Gbit/s,是当前光通信领域的研究热点之一。在未来多媒体用户接入网中OTDM技术与DWDM技术相结合 (OTDM/DWDM) ,可以发挥各自的优势以获得更高的通信速率及更多的用户数 ,是一项具有美好应用前景的技术。OTDM技术有优势也有挑战 ,还有很多问题需要解决 ,只有这些问题得到解决 。OTDM can increase single channel bit rate to hundreds of Gbit/s despite the limit of electronic bottleneck as it uses the composition technology of optical pulses.It is one of the research hot topics in optical communication field.In the future multimedia subscriber access networks,OTDMoften combines with the DWDM(OTDM/DWDM)exerting each advantage to reach higher bit rate and more subscriber users.So OTDM/DWDMis a technology with good applied prospect.OTDM has both advantages and challenges.There are many problems to be solved before its advantages can be exerted enough.
