According to IHS iSuppli, telco VDSL technology is getting a new lease on life after having been nearly written off, as a bridge between older ADSL technologies and faster but much more expensive fiber-to-the-home (FTTH). VDSL with vectoring answers the threat posed by DOCSIS 3.0, while also avoiding the expense of FTTH.VDSL speeds range from 25 to beyond 100 Mbps and can support triple-play services over a single connection. In its current form as VDSL2 with vectoring, the technology could give telcos up to five years of breathing room before they need to start deploying FTTH in order to remain competitive, but the window could possibly extend to 10 years, IHS believes.VDSL - or Very-High-Bit-Rate Digital Subscriber Line - is set this year for 40% subscriber growth. The global installed base is expected to rise to 42 million, up from 30 million in 2012. The largest markets for VDSL, the most advanced form of DSL technology, are expected to be Europe and North America as well as parts of Asia.
