On Feb. 28, Verizon, in conjunction with Ciena and Juniper Networks, announced that the companies have recently completed a test in Verizon’s live fiber network to move 800 Gbps of data on a single wavelength.
As noted by the carrier, "5G promises blazing fast gigabit speeds, super low single-digit millisecond latency, and huge scalability. It will be able to connect billions of devices and [move] terabytes of data from...use cases including video streaming, virtual reality, cloud computing, and machine learning and artificial intelligence. To move that much data, Verizon engineers are advancing the connecting layer of fiber as well."
The successful trial on Verizon’s live fiber network showed equipment interoperability from two different suppliers and the capability to quadruple the typical capacity carried on a wavelength. The test traffic was transmitted between two Juniper Networks QFX 5220 packet platforms across two Ciena 6500 platforms powered by WaveLogic 5 Extreme (WL5e) coherent optics.
“In the past, we needed to combine multiple wavelengths to achieve 800 Gbps capacity,” commented Kevin N. Smith, Vice President of Technology and Planning for Verizon. “Now, with the new optics configuration from Ciena and Juniper Networks on our fiber network, we are advancing our connecting layer of fiber to prepare for the explosion of data we know will come along with 5G’s transformational impact on industries and consumers. And being the only provider in the industry with that capacity on a single wavelength allows us to deliver the service at a much lower cost per bit.”
The carrier contends that use of the new coherent optics and equipment from Ciena and Juniper Networks demonstrates the technology evolution to a more software-driven and automated network with tunable capacity from 200Gbps to 800Gbps per wavelength, allowing Verizon to maximize efficiencies with the ability to optimize capacity for any distance and adjust to unpredictable traffic demands dynamically to meet customer needs.
“800G is possible today with our WaveLogic 5 Extreme technology and this live Network trial is remarkable because it shows the progression of capacity and efficiencies,” said Scott McFeely, Senior Vice President of Global Products and Services for Ciena. “Programmable 200Gbps-800Gbps transmission will allow Verizon to effectively respond to fluctuating user demands by creating a more software-driven, programmable and highly scalable network.”
“As network traffic continues to grow sharply, driven by video and other new 5G uses cases, it’s imperative for communications service providers and infrastructure vendors to work closely together for rapid innovation. New 400GbE packet routers and 800G coherent optical systems help drive down the cost per bit with improved scale and density. We’re excited to have played a role in this successful trial and look forward to help deliver new, high-bandwidth services to end-users," added Sally Bament, Vice President, Cloud & Service Provider Marketing, Juniper Networks
Verizon says it will begin deploying this new optical configuration in its fiber network in the second half of 2020.
