摘要
主要针对分布式基站及BBU-RRU间现有传输技术实现方式的优缺点进行对比,进一步介绍了在接入网引入的相干检测技术的特点,在此基础上对于UDWDM/HD-WDM技术优势和应用价值进行了描述,通过成本对比了解如何实现网络结构的简化和综合成本的下降。对于HD-WDM在中国移动前传的市场应用进行初步预测。另外提出如何培育符合G.Metro的未来有效市场。
It compares the advantages and disadvantages of the existing transporting technology implementation between distributed base station and BBU-RRU. It further describes the characteristics of coherent detection technology in access network. Based on the above, it describes the advantages and application value of UDWDM/HD-WDM. Based on the cost comparison, how to realize network architecture simplifying and the drop of comprehensive possessing cost is presented. It predicts initially the marketing application of HD-WDM in China Mobile fronthaul. In the other hand, it puts forward how to cultivate the future effi- cient market according with G.Metro.
