Adtran (NASDAQ: ADTN) shares began Thursday in the red, on announcing its role in the OIF’s open, multi-vendor interoperability demo at ECOC 2025 and highlighted its recent participation in the OIF Plugfest, where its 100ZR+ and 400ZRE coherent pluggables were validated across multiple hosts and platforms.
On the ECOC show floor, 100Gbit/s, 400Gbit/s and 800Gbit/s signals generated by coherent pluggable optics will be transported over open line systems (OLS) in a disaggregated IPoDWDM environment.
This includes a 300km Adtran FSP 3000 OLS multi-span link and Adtran 100ZR+ and 400ZRE coherent pluggable transceivers operating in third-party hosts and over both Adtran and third-party OLS.
This morning’s news release says the live setup demonstrates how operators can scale capacity with simple turn-up and integrated visibility while preserving vendor choice. Together, these activities underscore Adtran’s commitment to openness at both the system and module levels.
Said Ryan Schmidt, GM of optical transport at Adtran. “With our FSP 3000 open line system at the center of the ECOC demo, we’re showcasing a reliable 300km multi span link in a live multi-speed, multi-vendor environment, with simple activation and clear operational insight.
“This approach enables providers to expand capacity for cloud and AI workloads, reduce day-to-day complexity, improve energy efficiency and avoid vendor lock in while choosing the right technology for each role in the network.”
ADTN shares off 17 cents, or 1.8%, to $9.26.
