Power over Ethernet has become the new power grid in buildings. With new standards that allow up to 99W to be delivered, PoE has grown up and is ready to power connected devices throughout the office building, school, and hospital. Panduit’s latest ebook, The Role of PoE in the Modern Connected Enterprise, explores infrastructure considerations and emerging solutions for extending the distance of PoE delivery.
Panduit’s twisted-pair copper connectors meet the specifications of the IEEE 802.3bt standard for Power over Ethernet published in January 2019. That standard defines a maximum of 90 watts. While the standard itself is recently updated, Panduit’s certification to the higher loads has been in place since August 2016.
A recent technical application guide composed by Cisco, Panduit and Rockwell Automation describes how “Converged Plantwide Ethernet (CPwE) is the underlying architecture that provides standard network services for control and information disciplines, devices, and equipment found in modern industrial automation and control system (IACS) applications.”
As the industry adopts the latest generation of PoE technology for managing data and power over a single Ethernet cable, users face the challenge of making pre-standard powered devices (PDs) work alongside new IEEE 802.3bt-2018-compliant PDs in an existing Ethernet infrastructure. Microchip Technology Inc. has eased the transition with IEEE 802.3bt-2018-compliant PoE injectors and midspans for users and power sourcing equipment (PSE) chipsets for system developers that enable both pre-standard and IEEE-compliant PDs to receive up to 90W of power without changing switches or cabling.
If you’re working with Industrial Ethernet, you should know that cabling is by far the number one cause of failures. Watch this webinar replay to learn how to prevent and troubleshoot cabling.
This webinar replay reviews twisted pair cabling standards, cabling issues and testers for pre-deployment and troubleshooting.
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.
A wire map test may seem like the most basic test for copper network cabling and therefore one of the least important, but it is actually one of the most critical. And while the pair colors of blue, orange, green and brown might help you pass wire map testing, the test itself really doesn’t care about color at all.
Cabling Installation & Maintenance interviews Frank Straka, Panduit’s product line manager for copper products, about the Single Pair Ethernet Consortium, discussing the group’s objectives, the single-pair ecosystem, Panduit’s role in the group, and some forthcoming products related to this emerging technology.
In 1995, I attended a seminar in which the presenter told us that copper was dead, that we were approaching the limits of copper and that the future was fiber. However, fiber is not the answer to everything. The semiconductors that provide the processing power for the modern world are still electrical, not optical. Semiconductors create the data that must then be transmitted at rocket-ship speeds, and so the need exists for a copper connector that will allow extremely high-speed data to be taken from silicon to silicon, or silicon to fiber.
A new Ethernet protocol has been designed to operate over a single pair of UTP/STP cable – otherwise known as single-pair Ethernet. Although, individually, these devices don’t call for much power or bandwidth, the sheer number joining our networks (75 billion or more by 2025) will increase overall bandwidth needs.To discuss advances in technology, the Single-Pair Ethernet Consortium (SPEC) was formed, bringing together organizations that make single-pair Ethernet devices, equipment and connectivity. The group’s hope is to nurture the adoption and growth of single-pair networks in a standards-compliant ecosystem that discourages proprietary network types and instead makes use of Ethernet.
