NEW YORK Fiber connectivity received a strong endorsement Tuesday (April 30) when Verizon Communications' chief technology officer Mark Wegleitner called it "the ultimate move" for delivering broadband service to homes and businesses.
Though many operators have reduced capital spending and slowed broadband deployment, Wegleitner said the decline of traditional land line services mean the phone networks must change or risk becoming dinosaurs. The development of converged networks that can handle voice, data, and multimedia content will be key, he told the IEEE International Conference on Communications.
Operators looking to roll out converged networks will need a multitiered broadband strategy that integrates fiber, copper and wireless connections, Wegleitner said. That will require advancements on the DSL front, and fixed wireless solutions could expand broadband deployment, he said.
But fiber-to-the-premises will be especially important because it will allow operators to use dense wave division multiplexing (DWDM) to provision services on a wavelength-by-wavelength basis, he said. Over time, this level provisioning could be rolled out to end users. "Ultimately, the key is a fiber solution with wavelength availability," he said.
Before any of these services take off, operators must first deliver fiber connections, which have proved costly for carriers, Wegleitner said. He hinted that fiber broadband connections are more of a long-term solution, and said carriers need to push the broadband rollout forward.
Wegleitner did not mention a timetable for Verizon's fiber-to-the-premises service, but said the company is now running trials of the technology in Virginia.
