摘　　要：本文介绍超长距离(ULH)WDM光传输技术,并对与其相关的标准指标进行探讨。重点是OSNR和色散代价,提出ULH系统OSNR的要求为15dB,ULH系统也应考虑光通道代价指标,并主张可以放心使用Raman放大器。This paper introduces the WDM optical transmission technologies for the ultra-long haul (ULH), and, their standards and characteristic is discussed. The stress are the OSNR and the optical path penalty, to point out the 15dB for the OSNR of ULH system, to must be considered the optical path penalty for ULH system, moreover to affirm that Raman fiber amplifier is used to set your heart at rest.
