VDSL2 is expected to be a base technology for carriers deploying triple-play services and—more specifically—IPTV. The standard, designated as ITU G.993 and ITU G.998, is designed to let telcos transmit up to 100 Mbps on both the downstream and upstream paths over copper loops. For carriers that have opted not to roll out fiber to the home on a large scale, VDSL2 represents a reasonable interim measure to offer up to 200 Mbps of aggregate data, without the cost associated with connecting every home to fiber.
However, a number of issues have stalled the early phases of VDSL2 deployment. These include:
- The complexity of and the wide variance within the standards
- The difficulty of meeting the standards’ requirements in real-world environments
- The slow movement toward interoperability
After interviewing silicon vendors that make up the vast majority of the VDSL2 market, Yankee Group concludes that the widescale rollout of VDSL2 will be delayed until at least mid-2008. Additionally, the resulting delay will extend the lifespan of ADSL2+ as a base technology for triple-play deployments. Complexity Causing Delays
