Understanding Power over Ethernet Applications in Industrial Networks – IEEE 802.3af / IEEE 802.3at / IEEE 802.3bt

California, U.S.A., May 2018 – Ethernet Direct Corporation, a professional and primary provider of industrial networking and communication solutions offers a complete portfolio of Industrial Power over Ethernet devices ranging from Industrial PoE Gigabit switches, Industrial PoE Ethernet switches, Industrial PoE converters, Industrial PoE injectors and Industrial PoE splitters to meet the growing demands for various installations.

Power over Ethernet describes the standard which passes electric power along with data on twisted pair Ethernet cabling. This allows a single cable to provide both data connection and electric power to devices. Ethernet Direct offers the latest technologies in Power over Ethernet supporting IEEE 802.3af, 802.3at and 802.3bt. The original IEEE 802.3af standard provides up to 15.4W of DC power on each port. The updated IEEE 802.3at also known as PoE+, provides up to 25.5W of power for "Type 2" devices. The upcoming IEEE 802.3bt standard also known as PoE++ introduces two additional power types: up to 55 W (Type 3) and up to 90-100 W (Type 4). With a wide product offering, Ethernet Direct PoE devices are able to expand the use of various applications such as high-performance wireless AP, surveillance cameras, VoIP phones, network routers, industrial control system (sensors, controllers, and meters), access control system, intelligent lighting controllers and LED lighting fixtures, remote point of sales kiosks and more.

Ethernet Direct offers the latest technologies in Power over Ethernet supporting IEEE 802.3af, 802.3at and 802.3bt. The switches can be used to power IEEE 802.3af/at compliant powered devices (PD), eliminating the need for additional wiring and provide an economical solution for your industrial Ethernet network. Furthermore, we have integrated EEE and PoE. The IEEE 802.3az Energy-Efficient Ethernet (EEE) is a standard to reduce power consumption during periods of low data activity. The intention is to reduce power consumption by 50% or more, while retaining full compatibility with existing equipment. Ethernet Direct PoE managed switches support a wide variety of Ethernet functions including STP/RSTP/MSTP/ ITU-T G.8032 ERPS as well as advanced PoE management functions such as weekly PoE power scheduling, device auto-checking and auto-reset.
