Zayo touts 2H22 fiber network expansion and upgrades

Dec. 20, 2022
The initiatives include three new or overbuilt dark fiber routes, 18 new 400-Gbps routes, and a transpacific submarine route between the U.S. and Tokyo.

Zayo Group Holdings, Inc. says it has launched and/or completed 22 fiber route expansion and enhancement projects in the second half of 2022. The initiatives include three new or overbuilt dark fiber routes, 18 new 400-Gbps routes, and a transpacific submarine route between the U.S. and Tokyo.

The three dark fiber routes include a pair of new fiber networks. A new link from Cleveland to Columbus, OH, is more direct than alternatives, Zayo asserts. Meanwhile, a soon-to-be-completed network between St. Louis and Indianapolis will offer the lowest latency and most direct path between the two points, according to the company, while providing East-West customers a route that avoids Chicago. The third dark fiber network project involved an overbuild of the Las Vegas-to-Phoenix route to improve latency and add capacity. Zayo says it plans to add 400G capabilities to this route in 2023.

Zayo added such 400G functionality to 18 routes during the second half of this year. They include:

  • Atlanta to Orlando
  • Chicago to Columbus (direct)
  • Cleveland to Ashburn
  • Columbus to Ashburn (direct)
  • Dallas to Houston
  • Dallas to San Antonio
  • Denver to Dallas
  • Ft. Wayne to Chicago (via Indianapolis)
  • Houston to San Antonio
  • Los Angeles to Dallas
  • Omaha to Dallas
  • Orlando to Miami
  • Portland to Bay Area
  • Portland to Boardman
  • Seattle to Minneapolis (Canada route)
  • Salt Lake City to Denver (I-80)
  • Tampa to Orlando
  • Tucson to Nogales.

Finally, Zayo’s new transpacific undersea network runs between Hillsboro, OR, and Tokyo, Japan, and leverages the TGN-P submarine cable. The new route is Zayo’s third across the Pacific, joining runs on the PC-1 and Unity submarine networks. The new route provides diversity to PC-1 and features a diverse landing station in Tokyo. Zayo offers pre-provisioned and pre-tested 10G wavelength circuits on the new route, managed by Zayo’s network operation center (NOC).

Zayo says its network now comprises 16 million fiber miles and 137,000 route miles, with more expansion projects slated for next year. “Zayo is committed to supporting the needs of our customers, not only for today, but for the innovations of tomorrow,” commented Bill Long, chief product officer at Zayo. “Zayo is one of the only national providers actively pursuing new fiber builds, which have been enabled through our extensive existing infrastructure footprint, expertise within our teams, and the agile business structure Zayo has worked to build over the last 15 years. The continued expansion of our dark fiber and wave routes provides our customers with the customization and scaling ability they need to accelerate their digital transformation journeys.”
