Electrical contractors and engineering firms can do their part to prevent more cases of the coronavirus in their communities. For example, on its website, the National Electrical Contractors Association (NECA) has set up a Coronavirus Resource Center. The association offers the following tips from the Occupational Safety and Health Administration (OSHA) to protect workers.
Do understand what #5G actually is? Watch this on-demand discussion between two members of Corning’s Advanced Technology Team, Art King and Shirish Nagaraj, as they dig deeper into 5G, its capabilities, and what they think it will take to get us there!
Sure, you’ve heard of the #InternetOfThings. But, what about the #Ethernet of Things? Learn how more power from #PoE is helping to connect the world. Wired Ethernet connections may seem like ancient technology sitting in the rear-view mirror beside fax machines, dialup modems and dot matrix printers. Yet Ethernet, with its low latency, dedicated bandwidth and power delivery capabilities, is actually one of the key building blocks for the infrastructure that will enable the wireless IoT to continue to expand.
TIA’s TR-42.7 Engineering Committee on Telecommunications Copper Cabling Systems (568) has issued a call for interest for document ANSI/TIA-568.6, initially titled, “Single Pair Multi-Drop (SPMD) cabling and component specifications.” The standard will address the need to support applications that use a bus topology with multiple branches connecting communication devices.
One of the most important elements to the success of the Internet even from its earliest days nearly 40 years ago is Ethernet. Bob Metcalfe, known as the Father of Ethernet, came together with peers to invent and develop the Ethernet local-area network (LAN) technology and its system of packet protocols. This allowed personal computers to efficiently share files and printers, a major advancement for its time.
Industry standards such as Ethernet and USB help ensure the interoperability of the computers, peripherals, and networks we depend on every day. Compliance testing is essential because any level of incompatibility can be costly in time and money for vendors and end-users. Here’s a big surprise: if you peruse the compliance criteria, plug-and-play may be less robust than we might imagine. The underlying issue is the cascade of incompatibility percentages. When the interoperability numbers from connected devices are multiplied, the result is low enough to introduce significant risk. This is especially true for automated test systems.
Industrial Ethernet is very sensitive to delays caused by dropped or damaged data frames (sometimes called packets). Just a few dropped or damaged packets can cause a machine to shut down. These problems are often intermittent and can be caused by harsh industrial environments.
The IoT Community and the IEEE IoT Initiative are collaborating on activities to help accelerate the digital transformation of the Industrial Internet of Things (IIoT) and to speed the development of IoT for broader adoption across enterprise and industrial sectors. They seek to create a common industry language and framework in the areas of: Industrial IoT and Manufacturing; Smart Cities; Precision Agriculture; Healthcare; Security and Privacy; Computing and Information Processing; Communications and Connectivity, and other areas.
Selecting appropriate media for a robust and reliable industrial Ethernet network is imperative. Three viable media types can be used: optical fiber, balanced twisted pair and wireless. This article addresses the different characteristics of each medium and helps to identify the correct choice for the industrial environment and its specific applications.
High speed and low latency of the cable, high reliability and low-security threats, and features like easy installation and connectivity have boosted the growth of the global ethernet cable market. However, high installation cost and limited physical availability of devices hamper the market. On the contrary, rise in demand for power over Ethernet in industries is expected to create lucrative opportunities in the near future.
