Zayo Completes Transpacific Subsea Route Linking the U.S. with Tokyo


Zayo has announced a number of upgrades to the infrastructure of its independent fiber network, including an increase in long-haul capacity through the addition of three new, overbuilt dark fiber routes, 18 new 400 Gbps (400G) enabled routes, and a recently finished Transpacific subsea route linking the United States and Tokyo.

In addition to its current capabilities on PC-1 and Unity, Zayo’s most recent completed Transpacific subsea route, which uses the TGN-P cable to connect Hillsboro, Oregon, to Tokyo, is the third Transpacific route for the company.

The new transatlantic subsea route includes a diversified landing station in Tokyo and offers PC-1 a variety choice for a transpacific cable landing in the American Pacific Northwest. For improved client service, the route is maintained by Zayo’s network operating center (NOC) and is provided with pre-provisioned and pre-tested 10G Waves circuits.

Long-Haul Dark Fiber Capacity

With high-bandwidth dedicated infrastructure, Zayo’s new long-haul dark fiber connections link businesses and their clients to key markets throughout the world. The two new dark fiber lines from Zayo consist of:

  • Cleveland to Columbus – This recently finished route offers fresh variation from current routes and is more direct than other available routes, offering Zayo clients another routing choice into Columbus, a burgeoning data center and webscale market.
  • St. Louis to Indianapolis – When linking East to West markets, this route offers Zayo clients an alternate route option to Chicago that has the lowest latency and most direct approach when compared to other providers in the market. The route is anticipated to be finished by the end of 2022.

Along with the new dark fiber lines, Zayo has added more dark fiber capacity to the following route:

  • Las Vegas to Phoenix – Zayo clients will have adequate fiber capacity thanks to this low latency route, which would be rare along this route. Zayo plans to use the overbuilt fiber in 2023 to enable 400G capabilities along this route.

The new long-haul dark fiber routes give clients a variety of routing choices, the flexibility to upgrade and adapt their network to suit the particular requirements of their enterprises, and the chance to maximize resilience and scalability. The maximum level of security and redundancy is offered by the fact that these new lines are fully subterranean.

“Zayo is committed to supporting the needs of our customers, not only for today, but for the innovations of tomorrow,” said 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.”

“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,” said Bill Long, Chief Product Officer at Zayo.

In the second half of 2022, Zayo will add 18 additional 400G-enabled routes to offer high-bandwidth choices between important cities, including: 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.

Customers would be able to increase their bandwidth with Zayo on current routes thanks to the new 400G routes, which will also make high-capacity access available on new routes, improve network reliability, and improve customer experience overall through speedier delivery and more effective routing. These routes’ increased capacity would help clients meet their exponentially growing demand, which is being driven by new technologies like 5G, cloud adoption, IoT, AI, edge computing, and automation.

This series of infrastructure expansions from Zayo marks the latest in the company’s $250 million investment into its global infrastructure this year. Most recently, the firm added two additional 100G IP Points-of-Presence (PoPs) and 400G Wavelengths capabilities, expanding its infrastructure and Tier 1 IP network into the important border cities of McAllen and Laredo, Texas. In May, Zayo announced its greatest organic network growth to date. Celebrating its 15 year anniversary this year, Zayo’s network infrastructure footprint now spans 16 million fiber miles and 137,000 route miles.
