• New cooperation gives European cable operators a commercially open distributed access model for scaling ultra-high-bandwidth services while preserving long-term freedom of choice
• Ecosystem combines Vecima's Entra® vCMTS with Teleste's Remote PHY node portfolio and local sales and support presence

[TURKU, Finland / VICTORIA, British Columbia - 12 May 2026] - Teleste and Vecima Networks today announced a new cooperation in Europe to advance a commercially open distributed access ecosystem, combining Vecima's Entra® vCMTS cloud-native virtualized cable access core with Teleste's Remote PHY node portfolio and complementary local sales and support presence. The cooperation gives European cable operators a cost-efficient way to scale ultra-high-bandwidth services while preserving freedom of choice across the core and Remote PHY domains.

Under the cooperation, European operators can source the open, interoperable solution through Teleste's local sales and support organization, simplifying commercial engagement while preserving architectural flexibility. The commercial model is designed to keep multi-vendor choice commercially neutral: operators can select components based on network requirements without artificial additional costs related to interoperability or future changes in core or Remote PHY choice. The cooperation is non-exclusive, and both Teleste and Vecima remain fully open to working with all qualified vendors and supporting multi-vendor deployments based on operator preference.

"Operators want more than compatibility on paper. They want the freedom to choose the right building blocks for their networks today, without that choice becoming a commercial constraint tomorrow," said Ulf Andersson, Executive Vice President, Networks at Teleste. "The original promise behind OpenRPD was greater operator choice, and our cooperation with Vecima carries that thinking forward by making openness visible not only at the interface level, but also in the commercial model."

"Reliable. Flexible. Simplified. That's how Vecima is enabling the next phase of cable network evolution," said Ryan Nicometo, Senior Vice President and General Manager, Video & Broadband Solutions at Vecima. "Interoperability has always been foundational to our approach and, together with Teleste, we're enabling a seamless integration for European operators."

For operators planning their next phase of network evolution, the message is clear: openness in distributed access should not stop at technical interoperability. It should also be reflected in the commercial model and in the operator's freedom to evolve the network over time.
