HR Sees Core DWDM Surge

NEW YORK -- Worldwide sales of long-haul DWDM (dense wavelength division multiplexing) products grew by more than 30 percent in 2006, to $1.8 billion, as network operators scrambled to add capacity in the wake of surging demand for bandwidth, according to a major new report from Heavy Reading (, the market research division of CMP Technology's Light Reading (

Long-Haul DWDM: Market & Technology Outlook provides a detailed look at the long-haul DWDM sector through an extensive and exclusive survey of network operators worldwide; a forecast of the DWDM equipment market; and information gathered from direct interviews with carriers and suppliers.

The findings of this latest research reveal a market in the midst of an impressive recovery, as operators not only shore up capacity on their installed base of long-haul DWDM gear to keep up with demand, but also overlay routes or entire backbones with new gear to take advantage of the latest generation of optical equipment.

Long-Haul DWDM: Market & Technology Outlook addresses key questions now facing network operators looking to expand network capacity, including:

  • At what pace will backbone bandwidth demand continue to grow, and is there any way to "future proof" a core DWDM network?
  • How can network operators take advantage of new technologies to improve provisioning times and lifecycle costs, given their capital constraints?
  • How will the trend in the metro-aggregation network toward Ethernet and packet networking affect network operator decisions in the core?
  • Will growth in the core network be cyclical or linear?
  • Will wavelength services migrate to optical transport network (OTN) services? And will OTN migrate to a true networking layer, beyond Sonet/SDH?
  • Will 40-Gbit/s transport be squeezed out of the market by 100-Gbit/s Ethernet?
