Phihong and the History of PoE: Tracing the Evolution of Power over Ethernet Technology

The Birth of PoE Technology

Power over Ethernet (PoE) emerged to address a key challenge in the early days of IP phones: the inability to maintain power during outages, unlike traditional landlines. This limitation posed a significant problem, particularly for emergency calls. PoE technology was developed to provide a solution by delivering power through Ethernet cables, ensuring that IP phones could stay operational with a centralized UPS during power loss.

In 2003, the IEEE introduced the 802.3af standard, which officially standardized PoE. This led to its rapid adoption across various industries, powering devices like VoIP phones, IP cameras, and wireless access points. Today, PoE remains a cornerstone technology, enabling reliable and efficient power and data delivery over a single cable.

Milestones in PoE Evolution

The evolution of PoE technology has been marked by several key milestones, each contributing to its growing adoption and versatility. These milestones include the development of various PoE standards and the introduction of new products and solutions by industry leaders like Phihong.

Introduction of IEEE 802.3af Standard

The IEEE 802.3af standard, introduced in 2003, was the first official PoE standard. It defined the specifications for delivering up to 15.4 watts of power over Ethernet cables, enabling the deployment of a wide range of network devices.

Advancements with IEEE 802.3at Standard

The IEEE 802.3at standard, also known as PoE+, was introduced in 2009. It increased the power delivery capability to 25.5 watts, supporting more power-hungry devices such as PTZ cameras and wireless access points.

Expansion with IEEE 802.3bt Standard

The IEEE 802.3bt standard, introduced in 2018, further expanded PoE capabilities by supporting up to 60 watts (Type 3) and 90 watts (Type 4) of power. This standard enabled the deployment of even more powerful devices and advanced applications.
