摘要
目前,宽带战略取得阶段性成果,发达国家发展重心转向农村与偏远地区,全球宽带接入用户进入稳定增长期。发达国家宽带接入速率提升明显,发展中国家提升有限。技术方面,E/GPON设备、VDSL、DOCSIS3.0设备成为发展主流;TWDM-PON标准开始制定,矢量VDSL2取得突破进展。高带宽业务不断丰富和提升,视频、云计算、游戏是未来几年内主要高带宽应用。
Broadband strategy has achieved substantive results, the focus of deployment has been shiftedto rural and remote areas. Global broadband subscribers market has entered a stable growth period. Indeveloped countries, the broadband access rate hasbeen enhanced significantly, while in developingcountries it is still limited. Overall network coverage ishigh, but high and ultra-high speed broadband network coverage and broadband coverage in rural areasneed to be improved. E∕GPON, VDSL and DOCSIS3.0has become mainstream equipment; TWDM -PONstandard began to develop, and vector VDSL2 has getbreakthrough progress. High -bandwidth services areflourishing with applications like video, cloud computing, and gaming to become the mainly high-bandwidthapplications in the next few years.
