“Data Center Interconnect”
Data center interconnect (DCI) solutions have taken the optical transport market by storm, driven by webscale and Internet content providers' bandwidth demands. As customer demands on DCI solutions evolve, the design of these compact modular systems needs to evolve as well.
Cloud services are a shared economy in the IT industry, while data centers are the carriers of these services. Due to limited land resources and equipment room space, data centers are increasingly deployed in a distributed manner, requiring WDM technology to connect them to provide unified services.
According to the Global Interconnection Index released by Equinix, the DCI bandwidth capacity is expected to reach 13,300 Tbit/s in 2022, with a compound annual growth rate of 51%. This will be essential, as the government, finance, telecommunications, and other industries are increasingly dependent on the digital service ecosystem, driving demand for higher interconnection bandwidths.
The construction of enterprise-built DCI networks is key for the digital transformation of finance, government, and enterprise industries.
In modern times, the data center interconnect (DCI) domain is undergoing an innovation similar to the above-mentioned development from professional computers to PCs. Currently, the surges of DCI traffic are leading to an exponential increase in leased line costs, which severely suppresses the bandwidth requirements of various digital transformation applications. Given this, an increasing number of financial companies, governments, and large enterprises are considering building their own DCI networks.
Just as steam engines, generators, computers, and the Internet revolutionized society before, new 5G, AI, and cloud-driven technologies are doing the same.
Data center interconnect (DCI) serves as the foundation of enterprise digital transformation. DCI networks carry increasing amounts of services and require higher reliability.
Over the past decade, data center services have shifted from web-centric to cloud-centric. Today, they are shifting from the era of cloud computing and into the intelligent era.
