With the rapid development of data centers, super-large data centers are planning to move from 100G to 400G. High-density data center is becoming the director of the next-generation data center.
Keeping up with the evolving data center: part 1 – emerging technologies and related challenges – DCD
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.
As internet traffic, connected devices and cloud-based services proliferate, there is a corresponding increase in the deployment of optical fiber. This article will highlight the key market segments and technology enablers driving demand and then discuss the ways that optical fiber technology is being deployed to meet the demands for higher bandwidth, low latency networks.
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.
Structured cabling in the data center can help enterprise business thrive coming out of the pandemic
Hyperscale and large cloud data centers tend to be early adopters that shape the industry, with their practices ultimately becoming the standard for data center design and deployment. Current connectivity trends within these spaces are supporting the need to quickly and cost-effectively ramp up capacity in response to emerging technologies and the demand for high-speed, low-latency performance in the evolving digital economy and COVID-19 world.
Poor-quality cable and installation practices are often not a priority or much of a concern to building owners and end users until a system goes down. Because cable infrastructure is installed behind the walls and out of sight, few people give a second thought to the criticality of cabling infrastructure until it is too late. And don’t forget, wireless devices are in fact connected by wires to transmitters and routers. It is generally accepted that approximately 70% of network downtime is due to cabling improprieties, which can include low-quality cable or poor termination practices. But, even worse than network failure is the safety risk due to a cable’s poor design, substandard material makeup and/or manufacturing deficiencies.
Testing with both an OTDR and an OLTS is referred to as “Tier 2” testing within TIA standards and “extended” testing within ISO standards. Find out how OLTS and OTDR testers work, when to use them and how they complement each other when it comes to ensuring the performance of today’s fiber optic links in this free guide from Fluke Networks.

AFL’s new VFI4 Visual Fault Locator is an essential troubleshooting tool for fiber installation and maintenance technicians. The compact unit injects a high-powered red laser light that provides exceptional brightness and range for locating defects in single-mode and multimode fibers.
Edge computing sits at the intersection of artificial intelligence, the internet of things and big data and provides the flexibility of a hybrid model that can take advantage of both data center infrastructure and the cloud. By 2025, experts expect there will be 41.6 billion IoT devices, each equipped with sensors gathering information each second. It’s simply not reasonable for all that data to be streamed back to a central data center or traditional on-premises computing environment. By bringing compute power to the edge and integrating increasingly mature AI — a combination referred to as the “intelligent edge” — agencies can actually use this rapid expansion of data to help their missions.
