随着业务的不断驱动,以及人们对网络质量体验的不断提升,接入网正在发生翻天覆地的变化。从1892年至今,接入网经历了铜线语音、铜线宽带以及目前的光铜协同时代。近年来,随着视频点播、网络游戏和IPTV等高带宽业务的出现,用户对接入带宽的需求进一步增加,然而在长达100多年铜线网络的积累下,如何快速提升带宽,顺利过渡到全光网时代,成为目前各大运营商和设备提供商一大关注点。本文将通过对宽带发展现状和历史的分析,结合目前运营商的主要诉求,探讨现阶段接入网的光铜过渡难题和解决方法及下一代PON技术。
With the continuous drive of the business and the continuous improvement of the network quality experience, the access network is undergoing tremendous changes. From 1892 to the present, the access network has experienced copper voice, copper broadband and the current era of optical copper synergy. In recent years, with the advent of high-bandwidth services such as video on demand, online games and IPTV, the demand for access bandwidth has further increased. However, with the accumulation of more than 100 years of copper networks, how to rapidly increase the bandwidth and smoothly transition to All-optical network era, becoming the major operators and equipment providers a major concern. This article will analyze the current situation and history of broadband development, combined with the current operator’s main appeal to explore the access network of copper and copper transition problems and solutions and the next generation of PON technology.
