Traffic between data centers (DCI traffic) is growing faster than the other categories of traffic. This rapid growth is fueled by the increase in content distribution networks, the proliferation of cloud services and the need to move data between clouds and to the edge. There’s an ever-growing volume of data that must be replicated across different data centers which puts pressure on DCI networks to be flexible, resilient and adapt quickly to changing bandwidth demands.
The Data center interconnect (DCI), has been a primary driver for optical-fiber and fiber-optic cable manufacturers to develop products containing thousands of fibers. We refer to cables with 1728 or more fibers as ultra-high-density cables, and this article examines those products, gathering opinions from several industry experts.
The Dell’Oro Group reports that sales of optical transport equipment used for data center interconnect (DCI) increased 13 percent year-over-year in 1Q 2020. The segment is dominated by three vendors, Ciena, Cisco, and Infinera, who have a combined market share of over 70%.
The SN connector is a new, duplex optical fiber connector using LC style 1.25mm O.D. Zirconia ferrules, designed for next generation hyperscale data center interconnect (DCI). This connector was designed to provide individual and independent duplex fiber breakout at a quad style transceiver (QSFP, QSFP-DD and OSFP) that Senko contends is not only more efficient, reliable and scalable than the MPO connector but also at a lower in cost to implement. The SFP-DD has also adopted the SN as their independent duo style interface, mainly for the wireless fronthaul applications.
DCI is no longer just about data centers — it’s important for organizations to interconnect their data centers with cloud service providers (CSPs), global internet exchanges (IXs) and their customers’ and partners’ networks. They need the flexibility to connect their physical locations with CSPs and IXs to deliver truly cloud-centric solutions.
