Adtran today announced 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. 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.
