“Restricted reach has put limits on the business opportunity of VDSL2. By doubling the reach with minimum complexity in terms of upgrading, our technology demonstration shows carriers a potential to extend their VDSL2 offering to millions of new customers”, said Eduard Scheiterer, Head of Broadband Access at Nokia Siemens Networks.
A technology related challenge faced by VDSL2 service providers is that available bandwidth drops dramatically the further a customer is from a DSLAM (the network device that connects the various DSL subscriber lines to the main high speed internet connection.) Bonding is a process by which several VDSL lines can be virtually combined to expand the reach of the VDSL2 network, increasing the access bandwidth for customers.
