摘　　要：中国联通原有宽带网络的主要宽带接入方式为DSL方式。采用铜缆作为介质的DSL接入存在接入速率低、铜线老化等问题,已经不能满足用户的宽带需求。中国联通按照"宽带中国"战略要求,结合自身业务发展的需求,开展了宽带网络光纤化改造专项行动。本文主要介绍中国联通宽带网络光纤化改造过程的技术方案,特别是实现全部用户转网中对语音用户的转网方案。DSL is the main access mode of China Unicom original broadband networks. DSL, using copper as medium,has some problems such as low speed and copper line aging. Therefore, the networks can no longer meet the rising demands. Respond to the＂Broadband China＂strategy and meeting business development needs, China Unicom has launched the fiber optic renovation for broadband network.This paper introduces the technical schemes of the fiber optic renovation for broadband network at China Unicom, especially schemes which mainly benefit to transfer voice users of total users.
