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.
This handy infographic from Senko gives an overview on why you need a visual fault locator. A VFL helps you check polarity, find microband and macrobend points and check for light continuity and the location of broken fibers.
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.
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.
FOA has a online Loss Budget Calculator web page that will calculate the loss budget for your cable plant and a free app for iOS smartphones and tablets that will calculate loss budgets for the cable plant you are designing or testing.
VIAVI offers two free reference guides for fiber optic testing that can be downloaded as ebooks. Volume 1 reviews the basics in systems, standards, and network architectures and focuses on how to make the most of Optical Time Domain Reflectometers (OTDRs) to install, turn-up, and maintain fiber optic networks
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.
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.
Smart buildings use IoT devices that monitor building performance to bring benefits from staff productivity to sustainability through sensors and automated applications, as well as improving the experience of staff and visitors. This is particularly poignant at a time when hygiene and well-being comes under scrutiny in public buildings. IoT solutions are capable of helping businesses adhere to regulations, while also protecting the business from damage. Proximity sensors used for non-contact detection of objects are being used in car parks to indicate parking availability and can be used to manage people numbers in confined areas – especially relevant in social distancing measures. While pressure sensors are capable of detecting fluctuations or drops in pressure in water systems, used in conjunction with water quality sensors they can provide an important role in monitoring water quality.
Mission Critical and Panduit commissioned Clear Seas Research to conduct a survey measuring industry awareness and usage of edge computing solutions. 100 experts were asked how they would explain edge computing to someone new in the industry. Responses ranged from vague — “It’s modern and tech savvy,” to precise — “Putting the data near the user,” to eye-opening — “Not 100% sure myself.” Read the full report for more insight regarding the perceived challenges and benefits associated with edge computing as well as who should be involved in the decision-making process when it comes to deploying edge infrastructure and selecting the right vendor.
