The very best smart buildings harvest vast amounts of data from as many different sources as possible – building systems and sensors are capable of providing huge volumes of operational data regarding status, usage levels, maintenance needs and more. In the post-COVID era, IoT-driven, smart building technology can track the extent to which desks, meeting rooms and other spaces are actually used. Supporting apps can make it easier for colleagues to find and contact each other.
The climate impact of artificial intelligence — both in terms of power consumption and all the electronic waste that gadgets create — is a legitimate, growing concern. Research from the University of Massachusetts Amherst suggests the process of “training” neural networks to make decisions or searching them to find answers uses five times the lifetime emissions of the average U.S. car. Not an insignificant amount.
Over the past several years, Leviton has polled network professionals about the type of fiber they would install today, and we have seen solid growth in single-mode. In the March 2020 poll of 281 network professionals, more than 60% said they would install single-mode (OS2) today over multimode types, with OM4 coming in second at 28%. This change is largely a result of decreasing cost and recent standards committee activities that continue to promote more single-mode options for higher speeds such as 200 and 400 Gb/s. As this trend continues, the market in general will find single-mode a more enticing option. Let’s take a closer look at reasons behind its rise.

Siemon’s TERA cabling system supports 10BASE-T1L single-pair Ethernet (SPE), providing an easily-deployed, standards-based infrastructure that simplifies cable management, reduces costs, and enables more efficient use of pathway space. As explained in a new Tech Brief developed by Siemon’s Valerie Maguire, Distinguished Engineer and Chief Editor of the IEEE Std 802.3cg™-2019 10 Mb/s Single-Pair Ethernet project, 10BASE-T1L operation over TERA SPE cabling offers many advantages over traditional/proprietary operational technology for monitoring and controlling simple, low-speed devices in commercial enterprise environments.
As power densities of racks rapidly increase due to limited space, cooling efficiency is top of mind for companies in the industry. Cooling systems are very energy intensive, using as much (or more) energy as the computers they are created for, and they are expected to run continuously with the same effectiveness. Cooling strategies can be optimized by using computational fluid dynamics (CFD) simulation, which enables engineers to virtually test different data center designs, gain insights into airflow patterns, and discover “hot spots.”
Edge computing environments, including edge data centers, reset goals and customer expectations for the housing, protection and management of equipment, including cabling and network gear. In these environments, one-size-fits-all isn’t even a consideration. The concepts, approaches, and best practices described in this document position network administrators for success in establishing the technologies and techniques needed for managing computing at the edge.
New IEEE Std 802.3ca™ was approved by the IEEE-SA Standards Board on June 4, 2020. The standard defines two Physical Layer (PHY) specifications that support 25 Gb/s and 50 Gb/s EPON operation over a single strand of single-mode optical fiber and calls out two new EPON architectures — 25G-EPON and 50G-EPON.
Single Pair Ethernet (SPE) will open up new dimensions in Ethernet/IP data transmission, they say. Experts agree: SPE is becoming an application-independent, inexpensive key technology in the Internet of Things (IoT) and Industrial Internet of Things (IIoT).
TE Connectivity’s new Mini-ETH single pair Ethernet system for commercial aircraft offers substantial weight savings, more bandwidth and simpler installation and maintenance by using proven technologies from other markets. As designers search for greater efficiency onboard aircraft, TE’s new Mini-ETH system offers them up to 73% weight savings in cables and up to 41% weight savings in connectors compared to standard eight-wire cables and rectangular connectors.
