Webinar: VIAVI Solutions YouTube LIVE Ethernet Basics

VIAVI Solutions is hosting a live Ethernet Basics session presented by System Engineers, Dave Baker and Peter Desmarais. Attendees will learn Ethernet technology basics including line rates (10M to 400G), types of pluggable optics, link establishment processes, frame structures, key performance indicators, and best practices to test connectivity and service activation. The presentation will include tips and tricks for novices as well as experts.

Ethernet Alliance Single-Pair Ethernet (SPE) Executive Briefing, Part 1

Single Pair Ethernet (SPE) technology is expected to be a significant driver of Industry 4.0, bringing transmission speeds from 10Mbit/s to 1GBit/s across simplified cabling infrastructure, while saving space and weight. SPE promises to save factories time in setting up, maintaining, and operating industrial networks, while enabling power supply and better reliability of terminal devices through its Power over Data Line (PoDL) capability. Cabling Installation & Maintenance recently sat for an interview with Peter Jones, Chair, Ethernet Alliance and Distinguished Engineer, Cisco; and Bob Voss, Senior Principal Engineer, Panduit and an industrial automation industry technical expert and association member.

Rosenberger OSI adds MDC fiber connector to PreCONNECT fiber cable line

Rosenberger OSI will offer the Miniature Duplex Connector (MDC) as part of the company’s PreCONNECT fiber cabling systems which will increase the density of its fiber cable offerings. The MDC push-pull duplex connector is based on 1.25-mm all-ceramic ferrule technology. It is a Very Small Form Factor (VSFF) fiber connector that can be used as a media dependent interface (MDI) or optical interface for SFP-DD and QSFP-DD optical transceivers.

Reimagining smart buildings in the post-COVID era

Smart buildings equipped with IoT sensors will play a pivotal role in helping organizations achieve these objectives, notably by enabling Real-Time Location Services (RTLS), through which contact tracing can be conducted based on algorithms that rely on both proximity and duration of encounters. While IoT solutions like the Enlighted ‘Safe’ application can even help enforce social distancing rules and implement access restrictions based on real-time traffic and occupancy, while help facility managers set up sanitization schedules depending on the actual use of space and amenities.

Fiber Dispersion Will Change The Way You See Your Links

Optical data signals are comprised of very short bursts of light, or optical pulses. When we transmit optical pulses through fiber, they broaden. This means that they become longer in duration as they travel through the fiber. If the fiber is long enough, this broadening causes the pulses to overlap and interfere with each other, which impacts the receiver’s ability to resolve the transmitted data, resulting in bit errors. This pulse broadening is due to a phenomenon called dispersion and limits the transmission bandwidth and distance. Single-mode and multi-mode fiber are each dominated by different types of dispersion.

Webinar: To the Edge and Back

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.

Why the future-ready data center needs flexible cabling

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.

Usher in an era of light for campus networks by choosing fiber optics over copper

Traditional networks may seem adequate, but the exponential growth of data transfer is putting traditional campus networks to the test. In short, copper wiring limits speed and distance – and both are critical for an effective campus network. Copper only offers transmission speeds up to 1Gbps and reach of 100 meters; it will suffer signal losses and tremendous data slowdowns if they go beyond. Additional investment such as signal boosters or recabling are needed to maintain network performance if the site is particularly large.

Researchers set a new world-record Internet speed

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.
