Verizon Business Continues Building National Optical ULH Net

Verizon Business will add 6,000 more miles to its ultra long haul (ULH) network this year, surpassing the halfway point in the company's multiyear plan to deploy a 50,000-mile all-optical transport network across the United States. More than 15 new ULH routes connecting dozens of cities will be added.

Verizon said its ULH network supports integrated optical transport and enables photonic switching of wavelengths for network restoration and shorter customer provisioning intervals. The ULH strategy also allows Verizon Business to extend the signal reach beyond 1,200 miles without regeneration equipment, reducing operational expenses as well as the number of active components in the network. The use of ULH allows large-business and government customer traffic on the ULH network to receive a higher level of resiliency, better network performance, reduced latency and increased network availability, with measurements up to 99.999 percent.

The Verizon Business ULH network supports an OC-768 core capacity , with transmission speeds up to 40 Gbps for robust performance of IP, MPLS, SONET and SDH services. The network platform also has the capability of supporting a mixture of 10 Gbps and 40 Gbps signals on a single fiber.

  • Earlier this year, Verizon Business boosted the capacity of its ultra long haul (ULH) all-optical network from 10 Gbps line rate to 40 Gbps in the high-traffic corridor between New York and Washington, D.C. As the company began its 40 Gbps commercial deployment, it also confirmed that it already has 100 Gbps technology in its sights.


  • In June 2004, MCI (VZ Business predecessor), working in collaboration with CIENA and Mintera Corp., established a 40 Gbps connection across a long haul route spanning 1,200 km. The technology trial took place over MCI's ultra long haul DWDM route between Sacramento, California and Salt Lake City, Utah.
