Verizon Deploys 200G Technology on Section of Its Ultra-Long-Haul Network
NEW YORK – Building on its technology leadership, Verizon has completed a first office application of 200G technology by successfully deploying Ciena’s WaveLogic coherent optical processors, the latest in optical transceiver technology.
The 200G wavelength was provisioned in early December over approximately 200 miles on Verizon’s ultra-long-haul production network between Boston and New York, proving that 200G technology successfully works with existing network infrastructure without impacting live customer traffic carried on the same network and without making costly modifications to existing fiber or network equipment.
“As more and more of our lives are performed online -- by consumers and businesses alike -- the need for flexible and more efficient ways to carry traffic is essential,” said Ed Chan, senior vice president of network infrastructure planning at Verizon. “Moving toward 200G technology is critical to stay ahead of traffic growth driven by activities such as online video, LTE 4G and cloud usage.”
Like the successful 200G trial Verizon completed in 2013 with Ciena, this first office application deployment used advanced WaveLogic coherent optic capability. This solution allows more information to be carried on a single wavelength while increasing the distance it can be sent without additional loss of signal quality.
This FOA also validated the ability to double spectral efficiency by using 16QAM (quadrature amplitude modulation) on a single wavelength with the typical 50GHz channel spacing to increase the amount of traffic carried. The 16QAM technology doubles the number of bits per wavelength, allowing for twice the data to be encoded when compared with standard 100G technology.
“Building on the success of last year’s 200G trial, this is a significant step in Verizon’s ongoing efforts to deploy leading-edge optical capabilities across its network to deliver on-demand, high-bandwidth services,” said Francois Locoh-Donou, senior vice president, global products group, Ciena.
High-bandwidth technology continues to evolve quickly, with significant progress made during the past decade. Verizon has been a leader in high-bit-rate technology and was the first global carrier to deploy 100G technology on an ultra-long-haul route in 2009.
