There are several storage network protocols to choose from, including iSCSI, Fibre Channel and NVMe over Fabric. Review the performance, reliability, complexity and cost of each before deciding which one to use.
This article address multimode technology trends behind multimode fiber. It explains how cloud and enterprise data centers continue to drive strong demand for multimode solutions, even as transmission speeds increase and SMF transceivers move into the 500-m data space.
Over the past decade, data center services have shifted from predominantly web-centric to cloud-centric. Today, they are shifting once again, this time from the era of cloud computing to the intelligent era. There is a need to filter out and automatically reorganize the information before mining it for useful information. This is where artificial intelligence (AI) comes in. Some 97% of large enterprises around the world intend to use AI by 2025, according to Huawei’s Global Industry Vision (GIV).
Furukawa Electric Co has conducted an experiment in its Mie, Japan facility to demonstrate the installation of a 6912-fiber optical cable with an outer diameter of 1.14 inches (29 mm) in a 696 foot (200m) long conduit with three 90 degree curves and an inner diameter of 32mm. The conduit used was a standard product installed in conventional data center campuses. Engineers confirmed a maximum pulling tension of 84 pounds (372N), well below the maximum pulling tension of 600 pounds (2700N) specified for the cable.
This webinar gives data center managers some key cabling strategies to manage multiple waves of 5G — helping ensure next-generation coverage for billions of devices. Topics include the three phases of 5G deployment, data processing at the edge to reduce latency, and centralized data centers to support the workloads generated by 5G.
By far the most arduous challenge regarding optical fiber connectivity in the data center is managing the immense amount of fiber, whether it is in the demarcation point of the entrance room or within the facility itself. What used to be a few dozen or hundreds of fibers is now a few thousand. The trend we’re now witnessing is the revamping of the entrance room to eliminate outdated proprietary splice closures, affectionately known as “fridges,” so-called because of their physical resemblance, and replacing them with modern, more efficient and user-friendly high-density fiber management systems.
Researchers at University College London claim they’ve obtained a new top internet speed of 178Tbps – a fifth quicker than the prior record and fast enough to download the entire Netflix catalog in under a second. To achieve that, the researchers used different bandwidth ranges than are typically used in commercial optical systems. Traditional fiber infrastructure uses bandwidth of 4.5THz with 9THz becoming more available commercially. In UCL experiments, the scientists used 16.8THz.
Multi-fiber push on connectors (MPO) are a single connector that houses multiple fiber terminations, defined by IED=61754-7.14. The MPO’s rise in popularity is due to it’s ability to mate multiple fibers (2-72) within a single connector body, thereby significantly reducing the space needed.
Cloudlets, or mini-clouds, are starting to roll out closer to the sources of data in an effort to reduce latency and improve overall processing performance. But as this approach gains steam, it also is creating some new challenges involving data distribution, storage and security.
Transition Networks’ new PCIe 10 Gigabit Ethernet Fiber Network Interface Card (N-TGE-SFP-02), a PCIe 3.0 x8 bus card supporting faster transfer speeds of up to eight Giga Transfers per second (GT/s) optimized for data centers, offering connectivity flexibility and virtualization support.
