DEPLOYING 10 GIGABIT ACCESS NETWORKS

Using the Emerging NG-PON2 and XGS-PON Standards

Solution Overview UNDERSTANDING NG-PON2 ARCHITECTURE

Converging Multiple Services This flexible optics approach allows for mass market 10/10G NG-PON2/XGS-PON adoption for all broad- over a Common Access band applications (Figure A) while maintaining flexibility Services Architecture for the future overlay of an additional fixed optics 10/10G The primary value of NG-PON2 is the ability to serve business PON and/or multiple TDWM PONs using a mix of residential, business and backhaul services higher capability tunable optics (Figure B). over a common Optical Distribution Network (ODN) The ADTRAN NG-PON2 system elegance offers the using a mix of point-to-point and point-to-multipoint ability to benefit from mass market price points without technologies. The biggest challenge facing NG-PON2 having to wait for large volumes to be reached in the is coming up with a single system that meets the scale 10G PON market. This approach gives service providers and flexibility needs of premium business and backhaul confidence that they can move forward with a 10G PON services while also delivering on the price points needed strategy today, without the risk of depending on a future for mass market residential applications. worldwide volume ramp of 10G and tunable optics to make it cost-effective. On the OLT side, any mix of optics can be used on a single OLT, allowing for maximum Flexible Optics Balance flexibility without compromising on future capabilities. Cost and Scale Leveraging the additional capacity available through the Realizing that the major cost component of any disruptive ADTRAN NG-PON2 solution set, service NG-PON2 system is the cost of the optical transceivers providers can extract an additional five to ten years of (both at the OLT and ONT), ADTRAN® has developed revenue from this year’s residential PON deployments, a flexible optics approach to NG-PON2 that allows for maximizing future service flexibility and minimizing risk a single NG-PON2 OLT system to utilize multiple types of subscriber churn. of optical transceivers, allowing the service provider to better align the cost with the target application. Solution Programmability and a The flexible optics range from low cost fixed optics for residential, business and small cell broadband Commitment to Open Interfaces applications to fully-tunable optics for premium Simplifies Converged Operations enterprise, datacenter, fronthaul and backhaul Additionally, the operational cost and complexity to services. Through further innovation in the ONT connect a FTTH subscriber can be further reduced to optics design, ADTRAN has developed a fixed accelerate the expansion of Gigabit broadband services. optics 10/10G ONT solution compliant to NG-PON2, ADTRAN’s solution supports provisioning through XGS-PON, and GPON standards that allows for the modern, open APIs, facilitating the deployment in immediate support of NG-PON2 ONTs for business next-generation SDN-based management systems. and backhaul services as well as being able to seed Both the ADTRAN OLT and ONTs support open, the residential market with less complex NG-PON2 standard-based, physical interfaces allowing for the ONTs nearing the price level of today’s mainstream support of best-in-breed network design and the GPON ONTs. delivery of universal CPE across a multi-vendor network. This in concert with accelerated mass market electronics and optics pricing ensures that cost-sensitive residential broadband will be viable using NG-PON2/ XGS-PON technology.

XGS-PON is a fast developing standard supported by the leading service providers and vendors around the world for 10 Gbps (XG) Symmetric fixed wavelength PON over the already established GPON/NG-PON2 infrastructure.
