“光进铜退”是近年在电信业界普遍进行了技术应用和经营方式可行探讨的主题。据有关信息透露,中国电信等运营商内部存在类似这样的指导意见。随着IPTV、网络游戏等高带宽业务的应用,用户对接入带宽的需求将进一步增加,现有的以ADSL为主的宽带接入方式已经很难满足用户对高带宽、双向传输能力以及安全性等方面的要求。电信运营商已把关注的目光投向了FTTH,计划利用光纤这一迄今为止最优的传输媒质来突破接入的“瓶颈”。FTTH被视为下一代宽带接入技术的代表,是未来“最后一公里”的主体应用形式。
“Light into copper back ” is the theme of the recent technological feasibility and mode of operation of the telecommunications industry. According to the information disclosed, China Telecom and other operators within the existence of such guidance. With the application of high-bandwidth services such as IPTV and online games, the user’s demand for access bandwidth will further increase. The existing ADSL-based broadband access methods have been difficult to meet user requirements for high bandwidth, bidirectional transmission capability and security Sex and other requirements. Telecommunication operators have turned their attention to FTTH and plan to break the “bottleneck” of access with fiber, the best transmission medium to date. FTTH is regarded as the representative of the next generation of broadband access technology and is the main application form of the “last mile” in the future.
