The trial showcased the interoperability of 400Gbit/s WDM transport using Acacia’s and Inphi’s 400ZR pluggable transceivers with ADVA’s FSP 3000 DCI open line system (OLS) under real-world conditions. Results indicated that the combined systems exceeded OIF 400ZR specifications, demonstrating error-free operation over 120km with significant OSNR margins. This collaboration supports a multi-vendor ecosystem enabling open DCI networking using 400ZR technology.
