Rosenberger unveils PreCONNECT® SEDECIM cabling system: APC 8° angled polish optimizes return loss

Rosenberger has achieved excellent return loss values with APC 8° angled polish of multimode MTP®/MPO connectors. The APC 8° angled polish is used from the outset for singlemode MTP®/MPO ferrule endfaces to achieve reliable return loss. In contrast to this, only the PC 0° straight polish was previously used for multimode MTP®/MPO ferrule endfaces. Due to their PC 0° straight polish design, multimode MTP®/MPO connectors were previously particularly susceptible to performance problems caused by dirt particles, which in the past often led to unreliable return loss values.

The OM Mantra

Adopted by TIA, the nomenclature for multimode fiber found in the ISO/IEC 11801 standard includes the prefix “OM.” Rather than the spiritual mantra you hear in yoga class, most sources in our industry state that the acronym OM comes from “optical multimode” which seems rather obvious. But when it comes to the various nuances of each type of OM, the differences aren’t quite as obvious. There are currently five types of OM fiber—OM1, OM2, OM3, OM4 and OM5. OM1 fiber was the de facto choice for fiber throughout the 1980s and 1990s, and was still installed into the early 2000s. OM1 has a core diameter of 62.5 µm while OM2, OM3, OM4 and OM5 all feature a 50 µm core.

World’s fastest internet speed from a single optical chip

A research team has recorded the world’s fastest internet speed from a single optical chip of 44.2 Terabits per second.This technology has the capacity to support the high-speed internet connections of 1.8 million households in Melbourne, Australia, at the same time, and billions across the world during peak periods.
Demonstrations of this magnitude are usually confined to a laboratory. But, for this study, researchers achieved these quick speeds using existing communications infrastructure where they were able to efficiently load-test the network.
 

Monitoring the Impact of Health Outbreaks with Smarter Cities

The Center for Systems Science and Engineering (CSSE) at Johns Hopkins University has developed an interactive web-based dashboard, to visualize and track reported cases in real-time. The dashboard illustrates the location and number of confirmed COVID-19 cases, deaths and recoveries for all affected countries. It was developed to provide researchers, public health authorities and the general public with a user-friendly tool to track the outbreak as it unfolds. This along with other adjacent data sources can be used to effectively monitor and aid in the reduction of this and other outbreaks from spreading. China has reacted quickly to respond to the monitoring of the spread of this outbreak and Reuters reports that this could be forward looking to reshaping China’s smart cities.

Cloud Versus Edge — Is There a Winner? Complementary or Competitive?

At the risk of giving away the conclusion too early, there’s a clear place — not to mention, a need — for both application and infrastructure deployments in the cloud and on the edge. Centralizing data and the processing it in the cloud can be efficient and effective, but where latency can’t be tolerated, some amount of processing needs to be carried out at the edge. In fact, it’s often easier and more efficient to bring the processing to the data than it is to bring the data to the processing engine.

Webinar: How IoT Smart Building Solutions Increase Business Efficiency

Smart sensors offer a thorough view of building operations and provide vital insights into how energy is being used. Businesses can learn what devices are using energy, how much, and for how long. But IoT technology can provide more than just information, it can also help business owners manage the devices, like automating lights, adjusting thermostats based on time of day, or reducing energy provided to rooms not in use.
