How PON can evolve P2P fiber networks

In the initial stages of FTTH deployment, point-to-point (P2P) was the preferred architecture due to its symmetric bandwidth and intuitive design. However, as technology progressed, passive optical networks (PON) began to experience significant advancements. Not only did advancements such as GPON and XGS-PON, which offer 10Gbit/s symmetric bandwidth, push PON to the forefront, but global adoption also led to significant cost reductions. Moreover, in the context of rising energy expenses, PON’s efficiency has become especially beneficial. Compare this to P2P FTTH, which requires an individualized fiber and Ethernet port for each user. This approach increases power consumption, demands more space, and presents operational challenges. On the other hand, PON streamlines operations by sharing bandwidth, using energy more efficiently and simplifying the central office infrastructure.

Our close collaborations with European P2P operators stand as a testament to the advantages of transitioning to PON. In one of these projects, migrating a national P2P 1GbE network with multiple central office sites to PON resulted in an impressive 80% reduction in energy usage and an almost 90% decrease in rack space requirements. Replacing active switches with passive splitters led to additional energy savings, even enabling the operator to decommission some of its sites. Transitions like this require careful strategy and implementation. This is where the expertise and innovation of the Adtran team comes into play. With tools like our Mosaic Cloud Platform, we ensure smooth, efficient migrations.

Explore our white paper to delve deeper into the specifics of real-life use cases. Read more about the immense potential of PON, especially in today’s era of rising energy costs and increasing bandwidth demands. Discover how, as operators look to offer efficient multigigabit services to cater to the growth of smart homes, IoT, VR and XR experiences, shifting from P2P to PON is no longer just a smart choice – it’s imperative. And learn how proper planning and insightful modeling are crucial for a successful transition. In a world that’s rapidly digitizing and prioritizing efficiency, PON stands out as the frontrunner. Embracing PON isn’t merely about addressing today’s needs; it’s about gearing up for a demanding future.
