| 摘 要： | 高清电视、视频点播、云计算等新业务的发展要求光纤传送网带宽大并能灵活调度。文章讨论了几种实现传输速率为T比特每秒的超级信道产生方法。受电子＂瓶颈＂限制,T比特级速率的传输必须由多个密集的正交光子载波组成的超级信道承载。在每个光子载波上,可以采用基于正交频分复用的多载波技术,也可以采用单载波时域或频域均衡技术。通过调整光子载波的数目与颗粒度,或每个光子载波上承载的调制格式,可以实现可变速率的光传输与光交换。

| Abstract: | New services such as high definition(HD)TV,video-on-demand(VOD),and cloud computing require a large and flexible optical fiber transmission network.This paper highlights several ways of creating super channels that are capable of T bit/s transmission.Limited by electronic bottleneck,T bit/s transmission requires a super-channel with many intensive optical orthogonal subcarriers.Orthogonal frequency division multiplexing(OFDM)multicarrier technology and single-carrier technology with time or frequency domain... |
