Scott Wilkinson summarized the history and results of the OIF 400ZR implementation agreement. The efforts of OIF members resulted in the fastest ramping telecom technology in history and marked a turning point in the market from proprietary embedded WDM optics to interoperable pluggable coherent modules.
“400G pluggables built on the OIF 400ZR base and its extensions are now in their fourth year of commercial availability, and they have sold 3X the amount of any other coherent type at the same level of maturity. 400ZR modules are available from over 10 different vendors using DSPs from four different sources, and the number of suppliers continues to grow every year.”
