MONTREAL, June 25, 2025 — Conterra Networks, a Charlotte-based broadband provider operating across multiple U.S. states, has selected FONEX and the Open PON solution powered by Ciena’s pluggable microOLTs to upgrade its network to XGS-PON in a way that is both flexible and cost-effective.
Building on its already robust GPON foundation, Conterra sought a path to XGS-PON that would allow it to scale at its own pace and minimize upfront capital expenditures. With Open PON, Conterra can upgrade in smaller, manageable increments rather than committing to a full chassis investment.
The transition also preserves existing infrastructure: Conterra is building on its installed base of Ethernet switches, eliminating the need for new line cards or system overhauls. For business services, the deployment includes pluggable customer-premises optical terminals (ONTs) that offer enhanced performance, while maintaining the openness needed to support a wide variety of ONTs in a vendor-agnostic format.
This architecture provides Conterra with several key advantages:
- Significantly reduced CapEx by avoiding large-scale chassis purchases
- Incremental scaling aligned with customer demand
- Leverage existing switches to minimize disruption
- Support for multiple types of customer-premises optical terminals (ONTs), ensuring long-term flexibility
- Parallel operation with existing GPON, ensuring a smooth migration
“Open PON allows us the flexibility to enhance our existing carrier-grade access network quickly while minimizing large upfront investments. The partnership with FONEX and Ciena provides a solution that supports our growth and keeps us in control of the pace and cost of XGS-PON transitions,” said Mike Tompkins, Executive Vice President & Chief Operations Officer at Conterra.
The decision underscores the value of disaggregated, open networking for broadband operators. With over 30 years of experience as a trusted integrator, FONEX provided technical guidance, solution design, and ongoing support to ensure a seamless rollout.
