Benefits of Power over Ethernet (PoE)
Beyond cost and efficiency considerations, PoE-powered luminaires can be combined with sensors, wireless communication modules, and processors integrated into smart hubs. For electrical contractors, this technology offers a wealth of opportunities to streamline building automation, improve building efficiency, and provide value-added expertise and services. PoE technologies and PoE devices provide cost savings, easy installation, and increased flexibility for projects of all sizes
HOW POE TECHNOLOGY IS CHANGING THE LIGHTING MARKET
Power over Ethernet (PoE) technology allows LED lighting systems to take advantage of direct power, which is safer and cheaper to install than a traditional power infrastructure. The new white paper from Maxim Integrated Products explores how PoE technology can turn energy-efficient LEDs into smart sensor stations.
How does PoE work?
PoE lighting refers to the use of the same wires that are part of a structured computer network for the supply of electrical power. This allows a single cable to provide both a data connection and power to PoE devices, such as wireless access points and lights, PoE adapters, PoE switches and PoE ports, telephone systems, PoE cameras and LED lighting. Connecting smart LED lighting and sensor hubs to the local network provides valuable future-proofing by allowing installed LED hubs to quickly support technologies like the Internet of Things (IoT) without replacing the expensive lighting.

With the many applications of VoIP phones, IP cameras, and wireless access points, Power over Ethernet (PoE) has made great strides in recent years. It is expected to grow much faster in the future due to installation demand and newly adopted standards designed to support more smart devices.
What is PoE?
PoE is a technology that can transmit data and power over a single RJ45 Ethernet cable. It allows us to use RJ45 cables to provide data connections and power to wireless access points, IP cameras, VoIP phones and other powered devices (PDs) over a distance of up to 100m. Using PoE technology, we can easily supply power to PDs without the need to install additional electrical infrastructure or deploy power outlets.
What is the advantage of PoE technology?
Flexibility : Since Ethernet network cables are easier to deploy than electrical cables, PoE technology allows us to install PDs almost anywhere rather than near electrical outlets. This offers great flexibility for the configuration and positioning of the terminals.
Reliability : PoE power comes from a central, universally compatible source rather than a series of distributed wall outlets. It can be backed up by an uninterruptible power supply (UPS) or controlled to easily turn off or restart devices. This way, powered devices will operate as usual even if the power supply equipment (PSE) fails.
Time and cost savings : By using PoE technology on the network, the deployment of electrical cables and sockets for powered device terminals is not necessary. This will save electrical wiring costs, especially when there are many PDs in the network. there is therefore no need to hire a qualified electrician for the PoE network, saving you time and money on electrical installations.
What are the PoE standards and types?
The IEEE, Cisco and the HDBaseT Alliance have published several standards to qualify PoE lighting. These standards include IEEE 802.3af, IEEE 802.3at, IEEE 802.3at, IEEE 802.3bt, Cisco UPOE, and Power over HDBaseT (PoH).
IEEE 802.3af Standard : The IEEE 802.3af standard first establishes requirements for PoE power up to 15.4 watts of current without affecting the data rate of Ethernet networks. Power supply equipment conforming to this standard transmits PoE power over two of the four pairs in 10/100/1000BASE-T networks.
IEEE 802.3at Standard : This is basically an extension of the IEEE 802.3af PoE standard. The main objective is to give more power to the DPs. Compatible with the 802.3af PoE standard, the IEEE 802.3at PoE standard doubles the electrical power up to 30W.
IEEE 802.3bt Standard : The IEEE 802.3bt standard is the latest PoE standard that can power the 2.5G/5G/10GBASE-T network through standard Ethernet cable on all four pairs. It establishes two types of PoE, which are Type 3 and Type 4. Type 3 PoE provides up to 60 watts of power and Type 4 provides up to 100 watts.
Cisco UPOE : UPOE, short for Universal Power Over Ethernet, is a creation of Cisco. This extends the IEEE 802.3at standard to use all four cable pairs to deliver up to 60 watts of power, allowing for an extension of the types of devices that can be supported.
Power over HDBaseT (PoH) : Introduced by the HDBaseT Alliance, PoH is based on the IEEE 802.3at PoE standard and can be modified to allow safe distribution of up to 100 watts of electrical power over four pairs of Ethernet cables. It is designed as an economical and easy way to supply power to digital signage in airports, hotels, hospitals, cafeterias or any other environment that needs a video display – eliminating the need for AC electrical outlets.
What is PoE++ and what is a PoE++ switch?
In pursuit of additional power supply to expand device applications, IEEE 802.3 standard is once again required to upgrade its PoE+ technology to PoE++ ( IEEE 802.3bt standard ) in 2018. According to this standard, the technology PoE++ consists of two types.
