Interoperability takes compatibility a step further, focusing on the seamless integration of various systems and components within a data center. As data centers upgrade to 400G and beyond, they often integrate new technologies with existing systems. Enterprises can achieve data. OIF's live multi-vendor interoperability demo featuring 40 member companies at OFC 2026 will highlight real-world interoperability across key technologies including 800ZR, 400ZR, Multi-span Optics, Common Electrical I/O (CEI) CEI-448G, CEI-224G, Common Management Interface Specification (CMIS). Upgrading to 400G and beyond is an ambitious yet critical milestone for data centers. These ensure that new and existing components work seamlessly. Inside the box are a variety of compute resources, like CPUs, GPUs, accelerators, and smart network interface cards (NICs) that communicate with each other primarily through the PCI Express® (PCIe®) or CXL protocols. On the box-to-box side, switches and routers based on Ethernet standards handle. Taken together, the four US hyperscale cloud infrastructure providers (CIPs)—Oracle Cloud Infrastructure (OCI), Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP)—offer those standard commodities plus hundreds of highly differentiated and innovative services. Companies. The surging demand for cloud, AI, and data storage is fueling explosive growth in the data center market—creating major opportunities for OEMs to deliver integrated, high-performance systems that meet evolving power, cooling, and compliance needs.
