Data center interconnect (DCI) technology links two or more data centers, enabling the effective transport of multiple 10/40/100/400Gb Ethernet and 8/16/32G FC services over a DWDM fiber optical network. Today’s data centers have rapidly evolved from offering basic storage services to providing full scale connectivity, storage, and disaster recovery, which has become critical and regulated. The need to transmit massive amounts of data at any time, from any place, and from any device, for applications such as video, data backup and cloud services, has boosted market demand for high capacity links and seamless DCI.
