An ADTRAN Solution Overview Deploying 10 Gigabit SD-Access Networks Using 10G PON standards and data center principles to build next-gen broadband networks What is Driving the Need Applying Data Center SD-Access: Design-to-Operate, for Next-Gen PON? Architectures to Access Lean-to-Operate Emerging high bandwidth applications like 4K and 360º As telecom and cable operators look to optimise their SD-Access networks are highly agile with the automation video, augmented reality and virtual reality (AR/VR) networks, they are applying lessons learned from data and scalability needed to support mass market residential applications, autonomous vehicles and high-bandwidth center networks.

This agility enables telcos to retain enterprise applications are set to consume the capacity is an evolved access network strategy that uses open, their current market share and compete for new services levels supported by today’s Fiber-To-The-Home (FTTH) modular, component based architectures that leverage revenue.

SLA-based enterprise services using higher performance TWDM-PON optics (NG-PON2) Solution Overview 4 5 Mobilizing Software Defined Access The fronthaul, backhaul and crosshaul of densely deployed 5G radios is the industry’s most urgent and compelling use case for software defined access networks (SD-Access) using highly elastic Next-Gen PON tech- nology, with the potential to save billions of dollars in the build and operation of large-scale 5G networks. 5G promises connectivity 10 to 100 times faster than 4G networks, with response times less than 1 ms, making real-time applications such as remote surgery and driver- less cars feasible over mobile networks for the first time. However, mobile operators will need to deploy 10 times as many radio sites, each needing to be fed by a highly reli- able 10Gbps connection. To optimise the 5G business case and accelerate deployment, the ideal access network will therefore need to be highly scalable and programmable to provide the flexibility and agility to support multiple operators delivering a wide variety of premium and mass market services. Enabling Network Sharing SD-Access enables an enhanced form of network infrastructure sharing known as Fixed Access Network Sharing (FANS), allowing competing service providers to operate independently on shared, open infrastructure. FANS affords greater flexibility, control and visibility than other forms of unbundling, enabling new efficiencies that accelerate the availability and reduce the cost of ultra- broadband connectivity. Figure C: With support for ultra-low latency and network timing synchronization the same fiber network serving enterprise access services can be used to support x-haul services advancing 5G densification initiatives. X-haul connections for densely deployed 5G radios is the industry’s most urgent and compelling use case for SD-Access using highly elastic Next Gen PON technology. Solution Overview 6 7 Applying Data Center Architectures to Access With an open architecture approach, service providers have the freedom to choose best-of-breed elements and control the introduction and rollout of new customers applications and broadband technologies, eliminating high overhead costs.
