The demand for high-speed broadband is surging, driven by the exponential growth of AI and streaming traffic. The State of Disaggregation Report 2025 by RtBrick found that 81% of surveyed network operators believe their current architectures are unprepared for future bandwidth demands. To meet this challenge, multiple system operators (MSOs) and cable companies are augmenting and upgrading their legacy hybrid fiber-coaxial (HFC) networks with XGS-PON (10 Gigabit Symmetric Passive Optical Network) technology. However, this transition must occur without adding operational complexity, on limited capital budgets, and with a quick return on investment-a seemingly daunting task.

Historically, PON deployments were constrained by their telco style architecture, investment in the fiber plant, and limited customer demand, all of which failed to justify the cost. Today, with "fiber deep" architecture, remote/hybrid workforces, and an increasing need for symmetrical connectivity speeds to support interactive video communications and AI traffic, XGS-PON has become a viable technology for traditional MSOs. Yet, traditional PON service models can still be complex and offer limited deployment use cases.

What makes Cisco Routed PON different

Cisco Routed PON offers an innovative solution that combines the simplicity of PON with the intelligence of routing to deliver next-generation connectivity. It integrates Layer 3 intelligence directly into the access network, like a traditional cable modem termination system (CMTS), offering greater control with familiar information and functions.

Unlike traditional PON deployments where optical line terminals (OLTs) function as Layer 2 aggregation points and require traffic to be backhauled to a centralized router for IP services, Routed PON enables routing directly at the OLT. This approach reduces network layers, simplifies design, and brings advanced IP capabilities closer to the customer edge. In essence, Cisco Routed PON transforms the OLT into a distributed routing platform, delivering the scalability of PON with the operational benefits of Layer 3 IP routing. The integration of Layers 1, 2, and 3 into a single 1RU, I-temp platform enables service providers to deliver multiple revenue-generating services-including active Ethernet, cell-site backhaul, and PON-on one unified system. This convergence drives diverse revenue streams and significant operational savings, resulting in unmatched ROI and TCO in the industry.

How Routed PON delivers value for MSOs

For MSOs, Routed PON isn't just a technical upgrade. It's a strategic advantage. It unlocks new revenue opportunities, simplifies operations, and lowers costs across the board.

Unlocking network monetization and enhanced security

Routed PON enables MSOs to deliver differentiated services with stronger security and better performance. Key benefits include:

• Seamless integration: By bringing Layer 3 IP to the access edge, Routed PON enables end-to-end policy, quality of service (QoS), and segment routing for service differentiation and performance-based service level agreement (SLA) guarantees.
• Superior scalability for multigigabit services: The architecture supports symmetrical multigigabit speeds, allowing networks to keep pace with demand without massive redesigns or investments, enhancing service delivery for residential, business, and wholesale offerings.
• Pay as you grow: Unlike traditional PON platforms that require purchase of full capacity line cards, Cisco Routed PON allows MSOs to purchase and deploy OLT based upon the subscriber count and as the market scales.
• Simplified rural broadband: Integrating IP simplifies rural broadband networks, reducing the complexity typically associated with Layer 2 networks and leveraging converged transport based on technologies like segment routing or SRv6 for loop-free prevention. This solution can also incorporate Layer 2 (EVPN) and Layer 3 VPN services for redundancy and traffic isolation.
• Comprehensive security: Unlike Layer 2 PON, which relies on VLANs for subscriber isolation, Routed PON isolates customers with native IP routing, providing robust isolation. IP-based security policies, including firewall policies, anti-DDoS, and lawful intercept requirements are easier to implement and manage at the OLT level.

Simplifying operations from edge to core

Managing a broadband network shouldn't be a juggling act. Routed PON helps streamline operations by offering:

• Converged Layer 1 (Routed Optical Networking): Cisco routing platforms support a wide range of coherent optics with integrated EDFA amplification, enabling true Layer 1 convergence. By eliminating the need for traditional transponders and separate optical line systems, this solution delivers substantial OpEx and CapEx savings for MSOs.
• Reduced complexity: In traditional PON, traffic moves from Layer 2 (OLT) to Layer 3 (IP router) before reaching the core, involving multiple handoffs, VLAN configurations, and control-plane stitching. Cisco Routed PON eliminates these extra hops, leading to fewer network elements to manage, simplified IP addressing and policy control, and the elimination of large-scale VLAN management.
• Ideal for converged services: Routed PON provides IP at the edge for service backhaul, delivering video/IPTV alongside broadband without VLAN complexity and simplifying service orchestration across all access types.
• Smooth migration from HFC to fiber: Using Routed PON preserves existing service models and facilitates fiber overlay in brownfield or high-demand areas, extending the life of the existing HFC plant while reducing node splits.
• Cloud-native operations: Designed for a cloud-native operational model, Cisco Routed PON includes features like telemetry and model-driven programmability, enabling automated service turn-up, proactive troubleshooting, and optimized performance at scale.

Reducing costs while increasing efficiency

Efficiency isn't just about speed-it's about smart design. MSOs can use Routed PON to help lower total cost of ownership through:

• Reduced infrastructure investment: Routed PON integrates Layer 3 intelligence into the router via an OLT SFP, reducing the need for separate hubs and aggregation routers, which means fewer chassis and optics.
• Lower OpEx: It reduces operational expenses through lower power consumption, reduced rack space, and simplified operations. Fiber plants are also less costly to maintain than HFC, avoiding issues with cable sweeps, ingress/egress noise, and node splits.
• Streamlined provisioning: Powerful automation capabilities significantly reduce provisioning time, often to minutes, and minimize the need for expensive truck rolls.
• Enhanced network efficiency: Cisco Provider Connectivity Assurance enhances network efficiency and ensures SLA-based services by proactively monitoring and analyzing end-to-end and third-party connections, identifying and resolving issues before they impact service quality or user experience.

Built for the future of broadband

By collapsing layers and integrating routing intelligence directly into the access network, Cisco Routed PON empowers providers, MSOs, and cable operators to transform their networks with a future-ready, service-centric architecture. This approach drives immediate and sustained value through enhanced monetization opportunities, superior security, and operational simplicity, ultimately reducing complexity and costs. It supports scalable multigigabit services and converged applications, streamlines migration paths, and automates operations for greater agility.

In a world where broadband demand is only going up, Cisco Routed PON positions providers to capitalize on those opportunities, with resilient, service-centric networks that streamline operations, reduce costs, and deliver standout user experiences in a hyper-connected world.
