摘要
介绍新时期广电网络设计的一些新动向,包括1550 nm城域网、1550 nm市县联网、EPON+EOC技术的组合、高电平输出光接收机的大量使用和集中分配等,就这些先进的设计理念在广电网络中的应用提出自已的看法。
The new trend in the design of the broadcasting and television network in the new period is introduced, including the 1,550 nm metropolitan area network, the 1,550 nm fiber-optical join-network from city to county, combination of EPON and EOC technology, the massive use optical receiver of high level output, and Coaxial concentrator distributive network. The paper also gives some viewpoints on the application of advanced design idea in the broadcasting and television network.
