Interconnection, or cross connects, deliver a point-to-point cable link, predominantly through fiber, between two customers in the same data center. In turn, these cross-connects provide fast, convenient, affordable, and reliable connectivity and data exchange for data center customers, making them interconnected. In 2020, total interconnections, which includes both physical cross connects and virtual interconnections, reached 1 million globally.

Interconnection has grown in importance for data center customers as data integration, and low latency capabilities become higher priorities. Indeed, this prioritization of interconnection has resulted in 10% year-over-year growth in physical cross connects from 2019 to 2020.

At the same time, virtual interconnections are growing even faster at 50%+ year-over-year. Virtual interconnection growth is being led by data center providers such as Equinix. Additionally, third-party Software Defined Networking (SDN) interconnection platforms such as Megaport, PacketFabric, and Console Connect by PCCW are fueling the growth of virtual interconnections.
