Empowering What’s Next From Coast-to-Coast with 400G Wavelengths


by Aaron Werley, Vice President, Technology Zayo

Bandwidth requirements are increasing as companies execute digital transformation strategies.  This is driven by the need to transfer large amounts of data among enterprise and cloud endpoints as organizations increasingly operate from distributed, global locations. To answer this growing demand for bandwidth, we’re offering high-capacity Wavelengths on vital routes across the US.

This week at the International Telecoms Week conference we unveiled our first coast-to-coast 400G Wavelengths route. This network investment allows our customers to enjoy higher bandwidth connectivity in key locations from San Jose to New York City. Leveraging 400G, our customers can confidently invest in bandwidth-intensive technologies and create the innovations that will define our future.

Let’s take a look at what 400G enables for our customers and what’s next for Zayo.

Unlocking the potential of 400G

We’ve heard loud and clear from our customers across the US that our investment in 400G Wavelengths is necessary to support their capacity needs and enable next-generation technologies. Applications like IoT, AI and machine learning, high definition video traffic, 5G, Content Delivery Networks, and more require greater bandwidth to operate effectively. Our forward-thinking customers are already using these next-generation technologies to shape the future.

Zayo’s latest investment in our network to broadly support 400G Wavelengths brings significant performance improvements and the diversity customers are looking for to support the incredible capacity demands from edge to core and edge to cloud. Without the bandwidth needed to support them, these applications can be impacted significantly, negatively affecting operations.

Our modern, 400G wavelength-enabled optical network offers three main advantages to customers over earlier market offerings including:

  • Lower latency. With a predictable 60 milliseconds roundtrip delay from San Jose to New York City, Zayo’s 400G network enables real-time and latency-sensitive applications.
  • Higher capacity. Ultimately, the greatest benefit of 400G Wavelengths is that it offers more capacity in a single wavelength for businesses with growing capacity demands. These days, that refers to almost every business. In order to remain competitive in a digitized, real-time era, businesses must scale their capacity.
  • Reduced cost-per-bit. Customers reduce expense and simplify connectivity by leveraging one single 400G connection versus, for example, four 100G connections bundled together. Customers immediately save on cross-connect expenses. What’s more, 400G offers customers a reduced cost per bit over time.

Aside from offering more bandwidth with 400G, we’re building more automation into our network. This will reduce delivery times and inefficiencies to make Zayo more nimble as an organization and help us quickly address customer needs.

Preparing our network – and our customers – for what’s next

Speaking of the network, we’re making significant updates to our existing network and adding new routes to continue to empower what’s next. Our customers are transforming the way we live, connect, and work and we want to provide the foundation of these transformations with dependable, high capacity connectivity.

Fortifying our fiber network

Our ongoing network investments solidify Zayo as one of the major players in high-quality, fast, reliable networking around the world.  Zayo continues to create unique, low latency fiber routes as well as overbuild our existing unique network footprint.  We are making significant investments to improve the performance of our fiber plant, executing on a plan to harden the network to ultimately reduce fiber cuts and service degrades.

Our customers’ priorities are to increase network performance while reducing costs and our efforts are squarely aligned with those objectives.

Supporting everyone’s “new normal”

Aside from network requirements from our customers, the “new normal” of work has brought with it a dispersed workforce and cities that have become new hubs of innovation, making solid connectivity more important than ever for businesses everywhere. Our well-engineered fiber backbone lit with the best possible optical technology will continue to play an integral part in sustaining the hybrid and remote workforce.
