Overview
The evolution of industrial Gigabit Ethernet cards combining Power over Ethernet (PoE) functionality has mimicked the growing demand for higher bandwidth, increased power delivery, and rugged reliability in modern industrial applications. Initially, 1Gb Ethernet PoE cards dominated the landscape, offering up to 15.4W per port under IEEE 802.3af (PoE) and later up to 30W per port with IEEE 802.3at (PoE+). These solutions served well for powering peripheral devices at the time, such as Gigabit IP cameras (requiring 3W to 5W), PoE-powered panel PCs, etc.
With the emergence of bandwidth-intensive applications, such as high-resolution video surveillance, AI-powered edge devices, and industrial automation, came the need for faster data rates and higher power delivery. This led to the development of 2.5Gb and 5Gb Ethernet PoE cards compliant with NBASE-T standards, maintaining backward compatibility with Cat5e cabling while improving throughput. These intermediate speeds enabled smoother data handling at the cost of generating excessive heat, but without the need to overhaul infrastructures. As a result, efficient thermal management has emerged as a critical consideration in the design and operation of high-speed Ethernet connectivity.
The integration of 10Gb Ethernet for ultra-fast data transfer and IEEE 802.3bt Type 4 (PoE++) for power delivery, offering up to 90W per port, represents a significant advancement in supporting modern edge AI applications and ultra-high-resolution cameras. This combination meets the bandwidth and power demands of next-generation devices.
Challenges of Deploying 10Gb PoE++ Cards in Embedded Systems, in the Field
When 10Gb PoE++ industrial add-on cards are installed into industrial embedded computers, they unlock powerful new capabilities for a range of high-performance edge applications, particularly in intelligent factory, smart city and public infrastructure deployments. These add-on cards provide both high-speed data transmission and robust power delivery over a single Ethernet cable, streamlining installation and reducing the need for separate power lines in remote or difficult-to-access areas. This makes them ideal for outdoor high-speed WiFi 7/ 6 access points, PTZ cameras, AI-powered PTZ precision cameras, smart light poles, and kiosk information stations. In these scenarios, reliable power and high-throughput data are critical. At the same time, these application deployments pose thermal management challenges during operation due to environmental conditions, and both fast data throughput and power delivery will result in excess heat generation. Therefore, most add-on cards rarely have both 10Gb and PoE++, and will only have one or the other advanced specification to minimize the heat generated, to sustain operations.
For example, AI-enabled PTZ cameras deployed in applications such as traffic monitoring or port security often demand up to 51 watts of power via PoE++ (IEEE 802.3bt) and require a sustained data throughput of at least 1 Gbps to enable real-time video streaming, object recognition, and AI inference at the edge. However, the high-performance demands of these cameras also result in elevated power and thermal loads. In harsh environment conditions, there have been instances of PTZ camera failures caused by overheating, where the PoE card was unable to maintain continuous power delivery or data throughput. Such thermal-induced incidents can lead not only to device shutdowns, but also data loss and packet drops, compromising both system reliability and real-time operations.
In addition to performance, the card's durability is also essential. Installed in embedded systems that are often deployed in exposed environments such as roadside, intersections, harbor ports, or public spaces, they must operate reliably in a wide range of environmental conditions. Therefore, PoE cards used in these embedded computers must be capable of withstanding wide range temperatures, especially for high data throughput and sustained power output operations.
Power-hungry devices such as pan-tilt-zoom (PTZ) cameras, 8K ultra-high-resolution cameras (typically requiring up to 50W), wireless access points, and embedded industrial PCs can all be supported through a single Ethernet cable. PoE++ simplifies installation with streamlined cabling and efficient power management—key advantages for high-density smart city deployments across roadsides, seaports, industrial zones, agriculture fields, and mining operations.
