Carriers Pipe Up on DWDM Plans

What do carriers really think of DWDM? A Light Reading survey reflects high interest in the technology. But prospective buyers are cautious about cost.

More than 220 responded to the survey on Carrier Metro DWDM, which was conducted this week online after notifying a select list of readers. Of the group that responded, more than 50 percent plan to deploy new or additional DWDM/CWDM gear, most within the next 12 months.

But cost is a dealbreaker. Asked to list any drawbacks to deploying DWDM in their metro networks, 187 of those polled said high cost was a leading discouragement.

Still, there are major motivators, too -- also cost-related. Respondents rated the prospect of cutting operating expenses as the highest of several factors leading them to choose DWDM.

They also want to use the technology to offer new services and provision them quickly. The top five in their ranking of services are:

    1. LAN Interconnect services
    2. Wavelength services
    3. VPNs
    4. Wholesale services
    5. Private lines




Respondents were asked a range of questions related to the size of present and future DWDM/CWDM deployments, budget plans, and key features they're looking for.

The full results of the survey will be presented in Light Reading's upcoming Webinar, "Light Reading's 2002 Metro DWDM Carrier Survey," scheduled for Thursday, October 31, at 2 p.m. EST. To register, click: here
