用光纤取代铜缆是固网运营商对接入层网络部署的先进理念,是实现以“窄带+铜缆”为主网络向以“宽带+光纤”的网络转变。这种方式推动光通信技术演进通信世界。本文将通过通信网络发展的趋势来论述“GPON技术取代DSL”的必然性。
The substitution of optical fiber for copper cables is the advanced concept that fixed network operators deploy to the access layer network and is to realize the network transition from “narrowband + copper ” to “broadband + optical fiber ”. This approach promotes the world of optical communications technology evolving communications. This article will discuss the “GPON technology to replace DSL” inevitability through the development trend of communication network.
