In its largest network expansion, Zayo is upgrading its long haul dark fiber, 400G network and subsea routes worldwide. The investment will generate new and upgraded routes during the next 18 months.
The new 400G routes are between:
- Dallas and Atlanta
- Chicago and New York
- Denver and Chicago
- Denver and Salt Lake City
- Los Angeles, Phoenix and Dallas
- Salt Lake City and the San Francisco Bay area
- The San Francisco Bay Area and Los Angeles
Zayo points out that the Dallas to Atlanta route is the company’s third major east-west route and that a majority of the network will be 400G-enabled by the end of this year.
The new dark fiber routes, which are completely underground, are between:
- Cleveland and Columbus
- Dallas and Atlanta
- Denver and Salt Lake City
- Las Vegas and Phoenix
The company also said that it has hired more than 200 operations staffers in the service delivery, service assurance and network performance sectors.
Finally, the company updated its subsea operations. It said that its Zeus subsea cable, which will link London and Amsterdam, is nearing completion and that it recently completed what it calls a successful subsea 400G trial in the U.K. with Equinix.
“Enterprises of all sizes are entering a transformational, yet highly-complex time as they face a convergence of factors ranging from digital-first implementation and the future of work to rapid cloudification and edge computing,” Zayo President Andrés Irlando said in a press release. “At Zayo, we recognize that each of these advancements is only as successful as the connectivity empowering it.”
The 400G ecosystem is growing and evolving.
Last October, Windstream partnered with a company by the name of II-IV Incorporated on the development of next-generation transceivers. The goal is to streamline the deployment of 400G services and reduce costs, power consumption and network complexity.
In April of last year, Bell Canada announced a commercial 400G service using Ciena’s WaveLogic 5 Extreme Technology. At the time of the announcement, the service was deployed across major spans of Bell Canada’s 17,000 km fiber infrastructure.
