Data Center Interconnect (DCI) technology connects two or more data centers together over short, medium or long distances using high-speed packet-optical connectivity.

Data Centers house compute and storage resources for applications, data, and content.  And in this cloud-based, application-centric world, access to that data is a critical challenge.

Data Centers need to talk to each other—to share data and content and provide back-ups for redundancy. Fortunately, DCI technology enables the transit of critical assets over any distance, from across town to ultra-long trans-Pacific or trans-Atlantic oceanic links and everything in-between. Data may be carried across simple, point-to-point connections, more robust ROADM-based networks, or open line systems which support transport interfaces sourced from multiple vendors.

The most effective transport technology for DCI is next-generation coherent optics providing blazing speeds up to 800 Gb/s per wavelength. With a fast, reliable connection in place, physically separate data centers can easily share resources and balance workloads.

Some large operations use DCI to connect their own data centers within their extended enterprise infrastructures, while others connect to partners, cloud providers or data center operators to simplify data and resource sharing or handle disaster recovery needs.  Subsea cables are used to connect data centers and internet exchanges between countries and continents separated by vast oceans.

Some DCI applications need the highest level of capacity and scalability along with more software control and automation, while others can trade off some performance to meet a specific power profile and form-factor. 

Performance optimized DCI solutions are needed to overcome scalability and distance constraints to deliver higher capacity connectivity.
