Data-center power consumption holds steady

By on • ( Leave a comment )

A study published in the journal Science last week, notes that while global data-center energy consumption has risen over the past decade, a predicted explosion in power consumption by data centers has not manifested thanks to advances in power efficiency and, ironically enough, the move to the cloud. Data centers accounted for about 205 terawatt-hours of electricity usage in 2018,  roughly 1% of all electricity consumption worldwide. This represents a 6% increase in total power consumption since 2010, while global data center compute instances rose by 550% over that same time period.

Innovators wanted to develop augmented reality interfaces for first responders

The CHARIoT Challenge, sponsored by NIST, will award over $1 million in prizes for solutions that can emulate and transmit scenario-accurate data streams for augmented reality devices that will help public-safety personnel communicate and respond more efficiently. IoT devices streaming from smart buildings, city sensors and personnel monitors could provide first responders with real-time situational awareness.
 

Nokia boasts of 1.52 Tbit/s over single mode fiber

Nokia said it recorded speeds four times above the market’s current standard of 400 Gbit/s over fiber, transmitting at 1.52 Terabits per second (Tbit/s) over 80 km of standard single mode fiber — the equivalent of simultaneously streaming 1.5 million YouTube videos – which is four times the market’s current state-of-the-art of approximately 400 Gigabits per second.

Wi-Fi 6 – a Q&A for CIOs and network managers

By on • ( Leave a comment )

Wi-Fi 6 is the next-generation wireless standard. It’s faster than previous versions but more than just speed, it provides better performance in high-traffic areas, such as schools, large offices, factories, shopping malls, airports, and stadiums. The technology allows more Wi-Fi devices on a single network, where access points can communicate with more devices at once. Access points can send data to multiple devices in the same broadcast, and Wi-Fi devices can schedule check-ins with the access point. Together with 5G, Wi-Fi 6 helps build a more connected, intelligent network with uninterrupted connectivity.

Advice on overcoming common PoE challenges

Some people may have stayed home for this year’s OFC Conference, but optical innovation continued. This webcast will cover some of the major technologies and technical discussions originally planned for the OFC 2020 show floor. Insights from Lightwave Editorial Director Stephen Hardy and a panel of industry experts will help fill the knowledge gaps changes in travel plans may have created.

Webinar: Understanding Fiber Optic Cassettes

By on • ( Leave a comment )

Understanding the role of fiber optic cassettes will become increasingly important as companies move toward 40G/100G, and managing the cable plant becomes more complicated. Fiber optic cassettes help manage the fiber connections by simplifying cable management without running new cables. In high-density network applications, cassettes ensure the efficient use of space and enable quick deployment, high reliability which eases moves, adds and changes and allows network administrators to refresh frequencies. In this webinar, we will review the types of cassettes available and how they will help the migration to 40G/100G networks.
