Ovum is initiating market share and forecast coverage of optical networking equipment used for data center interconnect (DCI) beginning in 4Q15. This document offers description and segmentation details that we will use to track the DCI market.


  • Enterprise IT migration to cloud and the explosion of video traffic are driving strong growth in data center builds and fundamentally changing how networks are constructed. The ongoing surge in DC build-outs has made DCI the fastest-growing application for optical networking (ON) equipment. DCI revenues grew 12.7% in the rolling 2Q15 period, reaching $2.6bn. 
  • Most data center operators lease managed DCI services from communications service providers (CSPs), but a growing number of Internet content providers (ICPs), carrier-neutral providers (CNPs), and enterprises are securing fiber assets and building their own interconnect networks, causing shifts in market share for ON vendors. 
  • Growing numbers of data centers clustered in metro and campus environments are increasing the requirement for high-capacity, low-cost optical networking gear that is fundamentally different from traditional metro ON equipment, causing a drastic new design for equipment interconnecting data centers.
