VDSL port shipments reached a record level in the
first quarter of 2011, surging almost 50 pecent over the year-ago period,
according to Dell’Oro Group.
“With ADSL being a mature technology with
limited bandwidth capabilities, many service providers are upgrading their
networks with high-speed VDSL or PON equipment to enable new, high-bandwidth
intensive services such as IPTV. In many situations, VDSL is also being used as
part of all-IP network transformations that utilize multiservice access nodes
and soft switches with the goal of decommissioning older TDM
infrastructure,” said Tam Dell’Oro, president of Dell’Oro Group.
VDSL growth was led by shipments to EMEA, which
almost doubled over the year-ago period and accounted for more than 60 percent
of worldwide VDSL shipments.
North America was the second largest region
for VDSL, accounting for a quarter of total VDSL. The majority of these
were purchased by AT&T to support its U-verse IPTV service, the largest
fiber-to-the-node/VDSL upgrade project currently being deployed.
