Network X 2026 lands in Vienna from October 13 to 15, and LF Broadband will be on the show floor as part of the Broadband Forum pavilion. The pod is where several threads of the 2026 program come together: production VOLTHA and SEBA deployments at Tier 1 operators, the LF Broadband Community Lab, which helps vendors move from a working codebase to production, and the standards-to-implementation collaboration with the Broadband Forum. This post outlines what to expect, who to look for, and where to find us for an informal happy hour on Wednesday afternoon.
The LF Broadband pod, in the Broadband Forum pavilion
LF Broadband is co-located with the Broadband Forum in Hall B, Stand D25, partnering on the floor with two LF Broadband members: Netsia and Radisys. Both companies hold Governing Board voting seats, and both contribute directly to the technical work behind VOLTHA and SEBA. That means visitors can talk with people who contribute to the code and integrate it into operator networks, not just hear the marketing story around it.
The conversations we expect to have on the floor cluster around three areas.
Real-world VOLTHA and SEBA at Deutsche Telekom and Türk Telekom
VOLTHA is in production at Deutsche Telekom, running as a vendor-neutral abstraction layer across a multi-vendor PON estate. The Access 4.0 program has moved in-service OLTs within maintenance windows, applied zero-touch provisioning through the POD Access Orchestrator, and reduced dependency on single-vendor solutions. At Türk Telekom, SEBA and VOLTHA together support a whitebox OLT ecosystem with four vendor OLTs in production and two more in progress, serving 650,000 homes passed and growing, with measurable CAPEX and OPEX reduction. These are the deployments the team will unpack at the pod, with the operational detail that only makes sense in a one-to-one conversation.
Pre-production integration testing in the LF Broadband Community Lab
The LF Broadband Governing Board funds the LF Broadband Community Lab to help close the gap between a working codebase and a confident vendor rollout. Run by the VOLTHA TST, hosted by Deutsche Telekom, and supported by BISDN, the lab is open to all LF Broadband ecosystem members. It provides continuous integration testing, including hardware, of multi-vendor OLTs and ONTs against real-world operator use cases from Deutsche Telekom and Türk Telekom. It also tests against the VOLTHA and SEBA reference implementations, which incorporate BBF TR-385, TR-383, and WT-525. Vendors that participate in the program are recognized by LF Broadband operator members and the larger industry.
The point of that testing is simple. Operators get equipment tested end to end, not just spec-checked, so they can procure with more confidence. Vendors get pre-production integration that shortens the path to production. The lab is aimed at OLT and ONT vendors pursuing production deployments with operators like Deutsche Telekom and Türk Telekom, at operators running or planning multi-vendor PON estates, and at new members looking for a faster path from lab to production. Come by the pod to talk through how to engage with the lab and where it fits in your next PON procurement cycle.
The Broadband Forum collaboration and BASe programming
Being physically in the Broadband Forum pavilion reflects the way the two organizations work together year-round: BBF defines requirements, interfaces, and data models; LF Broadband turns those into implementations that operators can test, improve, and run. That collaboration is on full display at Network X in the BASe sessions, which are included with Network X registration.
LF Broadband member Radisys is on the BASe panel “Beyond the Bit: The Multi-Gigabit Access Evolution,” from 10:30 to 12:00 CEST on Wednesday, October 14, represented by Prakash Siva, SVP and Head of Technology and Architecture. The session looks at converged access across DOCSIS 4.0 HFC, mmWave FWA, and 50G-PON FTTP under a unified SDN control plane. It is one of four BASe sessions running across Tuesday and Wednesday. The operator-only roundtable, “The Operator’s View of the Opportunities in 2027 and Beyond,” closes out Wednesday’s program from 13:30 to 15:00 CEST and includes LF Broadband Governing Board voting representative Dr. Mehmet Özdem of Türk Telekom. The full BASe agenda is on the Broadband Forum site.
The LF Broadband happy hour
Wednesday, October 14 at 15:00 CEST, at the LF Broadband pod in the Broadband Forum pavilion, Hall B, Stand D25.
The operator roundtable wraps at 15:00, and that is when the happy hour opens at our pod. If you have spent the day in BASe sessions and want a place to continue the conversation with the community that turns those requirements into code, and a beer, this is it. The LF Broadband team will be there alongside members of our community. No agenda, no slides, just the conversations that shape what LF Broadband works on next.
Come find us
Network X 2026 runs October 13 to 15 at VIECON in Vienna. The LF Broadband pod is inside the Broadband Forum pavilion, Hall B, Stand D25. LF Broadband community members save 25% on registration with code LINUX25.
See you in Vienna.
