Sprint deploys longest 100G circuit

Sprint has deployed one of the longest 100 Gbps circuits in the United States with a live transmission that required no signal regeneration over a distance of 2,100 km.

The trials validate Sprint’s leadership in deploying new network technologies designed to meet exponential growth in demand for data by Sprint business and consumer customers. This includes bandwidth-intensive cloud services and other applications like streaming HD video, telepresence and high capacity datacenter connectivity.

Until recently, the Sprint network offered wireline services at speeds of up to 10 Gbps. The trials demonstrated the viability of using innovative technology to achieve speeds up to 10 times faster (and up to 40 times faster in the future), without requiring costly network upgrades to Sprint’s robust fiber infrastructure.

Sprint Ethernet Wave Services will support 100 Gbps speeds now, and Sprint expects to leverage Ciena’s coherent optical technology to support services operating at 400 Gbps in the future.

The 100 Gbps circuit trialed earlier this year is now integrated into the Sprint optical network infrastructures and is in-serviced between Chicago and Fort Worth, Texas. The 100 Gbps link uses Ciena WaveLogic 3 coherent optical processors on the 6500 Packet Optical Platform to enable Sprint to successfully transmit data at 100 Gbps over the 2,100 km circuit, with no regeneration of the signal at points in between.

The longer distance between regeneration points provides reduced latency, hardware benefits and improved reliability, flexibility and performance for customers.

“Customers have expressed their hunger for higher speed networks to support their substantial data needs, which we project will only continue to grow exponentially,” said Wayne Ward, vice president-Business and Product Development, Sprint.

“The 400 Gbps trial demonstrates our ability to offer higher speeds with our existing fiber, which means that our customers can feel assured that our network is future-proofed to meet their needs as they evolve. The delivery of 100 Gbps and 400 Gbps speeds will be critical as we launch our Ethernet Wave Services and support a growing wireless infrastructure.”

As announced in 2012, Sprint is upgrading its optical backbone network with Ciena’s 6500 Packet-Optical Platform as part of its Network Vision initiative. The advanced network is expected to enable Sprint to enhance transport network scalability, cost and performance. By adding Ciena’s coherent optical technology to the mix, Sprint can scale its core network initially to 40Gbps and 100 Gbps, and later to 400 Gbps and beyond, as network demands dictate.

“Service providers are increasingly challenged to satisfy surging demand for bandwidth-hungry services and applications,” said Francois Locoh-Donou, senior vice president-Global Products Group, Ciena.
