ADTRAN NG-PON2 Interop Trials to Improve SDN/NFV Network Automation

By Michael Guta January 25, 2017

Whether it is in the delivery or creation of services, speed is critically important in today's digital communications ecosystem. For traditional telecoms, introducing products to market faster means being able to compete with OTTs that are increasingly taking more of their marketshare. The NG-PON2 interop trials that were just completed by Verizon, along with participation from ADTRAN Mosaic SD-Access solution and several technology suppliers, concluded the expansion of bandwidth flexibility, with the goal of providing rapid service creation and maximizing Software Defined Networking (SDN)/Network function virtualization (NFV) network automation.

The NG-PON2 or ITU-T G.989 telecommunications network standard was developed by ITU in 2015 for passive optical network (PON). This standard ushered in multi-gigabit broadband experience for residential and business subscribers using TWDM (Time and Wavelength Division Multiplexed) technology and supporting from 4 to 8 wavelengths of 10 Gbps PON over a single fiber.

“Verizon has chosen NG-PON2, which is an ITU-T-developed international standard, for its next-generation network. This technology is the foundation for providing services that deliver multi-gigabit speeds,” said Dr. Denis Khotimsky, Distinguished Member of the Technical Staff and Verizon’s lead engineer on this trial.

The NG-PON2 trial was carried out with Verizon's Open OMCI specification, and it concluded multi-vendor solutions can greatly expand the bandwidth without impacting existing broadband subscribers on the same fiber line for both the optical line termination (OLT) on the service provider end and the optical network terminal (ONT) on the customer end. It also showed the service scalability and operational elasticity that NG-PON2 provides improved with the highest level of bandwidth flexibility, which will improve SDN/NFV network automation.

The ADTRAN Mosaic Software Defined (SD-Access) solution was used in the trial by delivering converged 10G services through the highly-scalable ADTRAN SDX network elements and SDN orchestration from the ADTRAN Mosaic Cloud Platform. According to ADTRAN, the highly-elastic multi-10G access technology is suited for carriers such as Verizon, so they can accelerate their transition to Web-scale operation.

“Increased network integrity and improved application quality-of-experience differentiate NG-PON2 as a cost-effective fiber broadband solution. As the industry continues to move towards more open, programmable and scalable architectures, ADTRAN is helping carriers like Verizon make this critical business transition,” said Robert Conger, ADTRAN’s associate vice president, Cloud and Portfolio Strategy.

With NG-PON2 technology, Verizon will be able to easily increase system capacity with SDN/NFV network automation and be able to add wavelengths to meet ultra-high definition video, virtual reality applications and cloud services traffic demand.
