当今社会,网络技术迅猛发展,以往各种网络传输界限日渐模糊,“三网融合”的时代即将到来。目前大部分广电网络仅仅基于单向传输功能,不能真正带动有线电视的突破性发展。而采用EPON+EOC技术将现有广电网络改造成既能够承载原有的传统电视业务,又能够承载交互式数字电视、高速数据上网、VOIP等业务的广电全业务网络是一种可行的改造方案。本文着重介绍EPON+EOC技术的特点及设计思路。
In today’s society, the rapid development of network technology, network transmission boundaries in the past increasingly blurred, “triple play ” era is coming. At present, most radio and television networks are based on unidirectional transmission functions and can not really drive the breakthrough development of cable television. The use of EPON + EOC technology will transform the existing radio and television networks can both carry the original traditional TV business, but also be able to carry interactive digital television, high-speed data access, VOIP and other services radio and television business network is a viable transformation program . This article focuses on the characteristics of EPON + EOC technology and design ideas.
