Cloud-to-edgePON solutions for cable operators Bring HFC and FTTH together with a future-ready network that’s built for efficiency1 Cloud-to-edge PON solutions for cable operators Bring HFC and FTTH together with a future-ready network that’s built for efficiencySeize the opportunity for next-generation broadband servicesDeploy a flexible, unified network with a built-in competitive edgeNext-generation PON technologies already deliver speeds of 10Gbps with a roadmap to 25, 50G and beyond.But deploying a new network technology comes with challenges—high costs, a lack of skilled labor, and the need to maintain two networks, to name a few. What if you could deploy a cloud-to-edge next-gen PON solution suite that’s flexible enough to ease the transition from HFC to PON and allows you to choose EPON or GPON technology—all while unifying network management and simplifying deployment?Now you can with CommScope.With subscriber demand for high-capacity broadband on the rise, MSOs are poised to deliver a new set of advanced services based on next-generation PON technology. But this opportunity is not exclusive to cable operators. Broadband competition is heating up in a range of markets, with billions in public funding fueling new fiber-to-the-home buildouts by service providers of all kinds in low-density and underserved environments.For cable operators, staying competitive and seizing the all-fiber opportunity does not mean walking away from existing investments in HFC networks and DOCSIS ®. The key to successful network evolution is to extend the lifespan of their existing networks, while deploying PON solutions that can coexist alongside them and provide an evolutionary path to what’s next.Leveraging CommScope’s flexible PON solutions and expertise, cable operators can transition to PON using the fiber strategy that makes the most sense for their business. This may include greenfield extensions of PON service to new neighborhoods or major footprint expansions using government funds. It may also include strategic overbuilds within existing HFC footprint, leveraging PON to create new service tiers for high-bandwidth residential and business subscribers to reduce traffic on the HFC network. Subscribers and services can then be added to PON networks over time to provide a gradual cutover that maximizes existing HFC investments while helping cable operators remain competitive.Cloud-to-edge PON solutions for cable operators Bring HFC and FTTH together with a future-ready network that’s built for efficiency 2CommScope’s deep experience with DAA has helped inspire our cloud-to-edge next-gen PON solution suite.

It uses interactive decision trees to help guide users through key decisions as they configure a customized broadband network design.Cloud-to-edge PON solutions for cable operators Bring HFC and FTTH together with a future-ready network that’s built for efficiency 6CommScope solves the unique PON challenges of rural deploymentIn rural environments, where housing density is low, deploying PON in a traditional centralized architecture can be a challenge from a cost and time to deploy perspective. However, MSOs can leverage their existing nodes infrastructure, available feeder fiber and take advantage of R-OLTs that can be housed into these nodes to significantly improve both time and costs of rural deployment. These benefits are revealed in detail when we review the key takeaways from a recent study conducted in an area with an average of 7.6 homes per mile (4.7 homes per kilometer). Similar to DAA deployments, the R-OLTs can be easily provisioned, monitored and new features updated in the field with additional operational efficiencies and savings coming from the use of a single management system for both technologies.Reduced facilities costs and deployment timeConstructing a traditional walk-in facility can cost hundreds of thousands of dollars per site and take several months to complete. But a 40-80% savings has been demonstrated with the re-use of existing housings and power available at the node and the use of environmentally hardened, smaller power footprint R-OLTs. We also found deployment time to be reduced by 70-80% when compared to the construction of traditional facilities, due to the reduction or elimination of costly and time-consuming permitting requirements.Increased hardware utilizationMany of today’s existing OLTs have been designed for high-density environments, which leads toinefficiencies in hardware utilization when they are deployed in rural markets. In our study, the use of environmentally hardened R-OLTs that can be deployed with low initial port counts and scaled through the addition of ports and the transition from a 1:128 split ratio to a 1:64 split ratio when more bandwidth capacity is required.Improved management and service efficiencyIn rural environments, it is critical to control the costs of networkmaintenance and management. We discovered that R-OLTs contributed to a reduction in the volume and complexity of truck rolls in low-density environments. These savings are derived from several features of CommScope’s R-OLT and ServAssure solutions, which include cloud-based management, zero-touch provisioning, proactive performance management, and the ability to deliver updates and new features over the network, which is similar with DAA deployments.Optimized outside plant investmentsCovering long distances with fiber to reach relatively few homes can strain the finances of rural service providers. But the fiber-efficient nature of R-OLTs combined with sound topology choices were shown to help. By placing the last active device deeper in the network, fiber counts and their associated costs were reduced substantially in the feeder network. Passive connectivity costs were driven even lower thanks to deploying R-OLTs deeper in the network. This allows CommScope’s cascaded, tap, and indexingtechnologies—which benefit from the increased optical budget—to be used, creating up to a 33% savings in labor costs.7 Cloud-to-edge PON solutions for cable operators Bring HFC and FTTH together with a future-ready network that’s built for efficiencyWhy CommScope?CommScope not only offers a comprehensive portfolio of solutions that spans multiple network architectures, but we also offer the expertise it takes to bring them together in a 360-degree view.

The partial connections in P-NEN further enhance the model's efficiency and prevent overfitting. However, there are still challenges in stock prediction, such as data quality and forecasting market trends during extreme events. Future research should focus on addressing these challenges and further improving the accuracy and reliability of stock prediction models.5. ConclusionIn this study, we propose a new approach called Partial Neural Evolution Network (P-NEN) for stock prediction. P-NEN combines the strengths of neural networks and evolutionary algorithms to enhance the predictive performance. Through experiments and comparisons, we demonstrate the effectiveness of P-NEN in stock prediction. We believe that P-NEN has the potential to be applied in real-world financial scenarios and contribute to more accurate and reliable stock predictions.References:[1] Zhang, Y., Cheng, J., & Zhang, G.
