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.
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.
Check out this article from #IEEE P802.3bt Task Force acting chair, Chad Jones on Power over #Ethernet (#PoE) classification and powering options. It provides a good look at the IEEE 802.3af and 802.3at #standards.
Fluke Networks demonstrated a prototype single pair Ethernet (SPE) adapter for its DSX-8000 at the Rockwell Automation Show. SPE is making waves in the industrial-automation world as a potential replacement for fieldbus architectures. The adapter is being made in very limited quantities and is currently only available to industrial automation and cabling manufacturers for their use in labs but has been released with the expectation that SPE will become widely adopted.
A new implementation agreement for low-power consumption will see small modules push technological barriers. One of few things to match large webscale internet content providers’ power in the modern world is their hunger for data. Consequently, they are shaping the optical communication industry to get the benefits of high-speed 400G technology in just the format they like.
New devices based on the 802.3bt standard will supply up to 90 watts over four twisted pairs, supporting a new generation of PoE-supported devices. This webinar will give you the background you need to specify, install and troubleshoot these devices, including: How it Works, Cable Bundling Considerations, Field Termination Considerations, Cabling Performance, and Installing and Troubleshooting.
LightCounting expects sales of Ethernet optical transceivers will have declined by 18% when it tallies figures for 2019. The decline is the largest the market research firm has recorded and the first year-on-year dip since 2009, when sales slipped 4%. However, LightCounting states in its new “High Speed Ethernet Optics Report” that purchases of Ethernet optical transceivers should rebound through 2024.
More than half of Industrial Ethernet problems can be traced to cabling. Testing cables when installed can speed the startup process and prevent problems in the future. This webinar co-hosted by Fluke and Panduit reviews twisted pair cabling standards, cabling issues and testers for pre-deployment and troubleshooting.
