摘要:

随着“宽带中国”战略的持续推进,宽带“提速降费”已成为“互联网+”战略实施的重要支撑。借鉴3G网络对2G进行逐步替代性创新的技术构想,提出利用原有传统接入的引入线,使用户外蝶形皮线光缆替代传统GYTA光缆进行配线,按需提供FTTH和FTTB充分融合的配线点(DP)的光纤接入“三明治”方案。通过光纤接入“三明治”方案在湖北联通的规模应用,有效实现固定网络接入的“轻资产”化和“高带宽”化。在下一代互联网接入背景下,对光纤接入“三明治”方案的技术先进性、经济合理性和相对成本优势进行了分析,并总结出该方案在“互联网+”通信基础设施改造中的应用关键点,对我国全面加快网络光纤化改造,促成网络“轻资产”化和“高带宽”化提出了管理建议。

Abstract:

With the continuous promoting of“Broadband-China”evolution,“Faster internet with cheaper tariff”in broadband field has become the important support of“internet+”.The optical access-sandwich solution was proposed based on the gradual evolution from 2G to 3G,which means reusing traditional incoming-line on the live network,distributed by replacing traditional GYTA fiber with butterfly-flexible optical cable and providing convergent DP in FTTH and FTTB. The asset-light and high-bandwidth on fixed access network can be achieved effectively with the large-scale deployment on the solution. In the environment of next generation internet,the advantage on optical access-sandwich,including advanced-technology and effective-cost,was analyzed. Meanwhile,the key point,which is reflected in the modernized telecom infrastructure in internet+,was summarized accordingly. The proposal,which included acceleration on optical-internet modernization and the asset-light & high-bandwidth on network,was put forward.

Key words: internet+, next generation internet access, optical-internet modernization, asset-light
