浅谈灰光OTN在中国移动城域网中的应用

Discussion on Application of Gray OTN in China Mobile MAN

根据中国移动OTN网络现状,结合灰光OTN的技术标准,分析传统彩光OTN和灰光OTN的优劣,在此基础上提出灰光OTN在城域网的组网方式和组网方案,以及灰光模式下末端集团客户的接入方案。该方案实现了接入层OTN的类SDH组网,一方面节省了机房的空间与功耗,另一方面也降低了投资,同时,类SDH组网方式也更符合网络维护人员的习惯。

According to the current situation of China Mobile OTN network,combined with the technical standard of gray OTN,the advantages and disadvantages of traditional color OTN and gray OTN are analyzed.On this basis,the network construction mode and scheme of gray OTN in MAN are proposed.The access scheme of group customer in gray mode is discussed.The scheme realizes the network construction of access layer OTN like SDH.On the one hand,the space and power consumption of the machine room are saved.On the other hand,the investment is also reduced.At the same time,the gray OTN,the network mode like SDH is also more adapt to the habits of network maintainer.
