Hello, everyone!
“Replacement of copper cables with optical cables” is an inevitable trend for the evolution of broadband networks.
In the course of network evolution, worldwide operators have adopted a strategy of providing multiple services. Their practice of bundling multiple services help them enhance their competitiveness, increase their ARPU, raise customer loyalty, and curb customer churn. As for the multi-service offerings, the operators both at home and abroad cast their attention on the IPTV service. Given the current encoding technology, IPTV provisioning, HDTV provisioning in particular, requires a bandwidth of 10 Mbit/s at least. To better provide the services that requires high bandwidth, the operators have to launch their broadband acceleration campaign. Otherwise, their goals of providing higher bandwidth broadband services and achieving strategic transformation will fall through.
No matter which DSL technology, ADSL2+, VDSL2+, or other future high-rate access technology, is adopted, higher bandwidth can be achieved only when copper cables are shortened. That is why mainstream operators worldwide is planning to or begin to get the DSLAM closer to the subscriber premises. “Replacement of cooper cables with optical cables” is a typical case of getting the DSLAM closer to the subscriber premises.
The cost-effective hybrid of VDSL2 and FTTH can solve the problems of the “last mile” : Optical cables, which are routed as near as possible to subscriber premises, are connected to the DSLAM or the DLC through the pipe buried in the ground. Within the last several hundred meters to subscriber premises, the VDSL2 technology is adopted to provide high-speed access.
Thanks.
