随着宽带中国战略的出台,以及对高带宽应用的预期,运营商启动并加快了FTTH建设步伐,FTTH建设时所存在的问题也不断涌现,其中光纤入户是最大的难题,阻碍了宽带网络升级的步伐。与FTTH接入方式对比,VDSL2的速率并不比FTTH的差多少,VDSL2的理论速率可达100Mbps,完全可以满足用户的需要,并且充分利用了丰富的铜缆资源,不需要改变用户入线,但VDSL2的有效距离较短,因此,VDSL2可以和FTTH互为补充,以较小的成本满足用户的带宽需求
With the introduction of broadband strategy in China and the expectation of high-bandwidth applications, operators have started and accelerated the pace of FTTH construction. Problems in FTTH construction are also emerging. Fiber-to-the-home is the biggest challenge, hindering the development of broadband networks The pace of upgrading. Compared with FTTH access mode, the rate of VDSL2 is not worse than that of FTTH. The theoretical rate of VDSL2 can reach 100Mbps, which can fully meet the needs of users and make full use of abundant copper resources without changing user access. However, The effective distance of VDSL2 is short, so, VDSL2 can complement each other with FTTH, meet users’ bandwidth demand with smaller cost
