VDSL2 Solutions for Competitive Broadband

The new decade has brought with it a dramatic leap forward in copper access technology. The emergence of VDSL2 promises to meet the ever rising demand for bandwidth in this decade. Internet download speeds of up to 100 Mbps per home are finally possible over existing copper – which, in conjunction with ubiquitous 10GE transport, ensures that service providers are able to expand their market share with advanced broadband services. For longer loop deployments, Calix DSLAMs support VDSL2 bonding to minimize the capital expense of deploying VDSL2 DSLAMs closer to the home.

The emergence of VDSL2 as the dominant copper access technology also heralds the end of ATM in the access network. While early generation "Ethernet DSLAMs" still required the use of ATM in the "first mile" for ADSL2+ services, the latest generation of Ethernet DSLAMs and VDSL2 line cards utilize Packet Transfer Mode (PTM) instead of ATM for VDSL2 and ADSL2+. This simple change delivers a 13% increase in throughput even for long loop ADSL2+ deployments. And because VDSL2 incorporates all prior DSL versions, service providers are now able to deploy a single future-proof technology for all their copper access needs.

The Calix B-Series, C-Series, and E-Series (E3, E5, E7) all provide support advanced VDSL2 solutions.

Vectoring is an exciting new technology that can provide service providers with dramatic bandwidth improvements of up to 50% across their existing copper infrastructure. In this video, Teresa Sperry, Calix director of market development for multiservice over Ethernet, provides an overview of VDSL2 vectoring technology and demonstrations of the technology in both lab and customer network environments.
