永嘉县广电双向接入网改造方案选择

Yongjia County CATV Bidirectional Access Network Transforms Scheme

随着光纤技术的快速发展,光纤价格的大幅度下降,采用现有成熟的技术,广电运营商可以很方便地将户外光纤网络升级改造为双向网络,因此电缆分配网络的双向宽带接入网已经成为有线电视网络实现双向化的关键,探讨县级广电网络如何选择性价比最高的方案实现双向接入网改造,以成功实现战略转型。

Along with the optical fiber technology development, the price of optical fiber has dropped a lot. Using the existing mature technology, broadcast television operators may easily change the outdoors optical fiber network into the bidirectional network. Therefore the bidirectional broadband access network with electric cable assignment has already become the key of cable TV network bidirectional transformation. This paper discussed how to choose the scheme of the highest cost performance in the county-level bidirectional access network transformation.
