PoE Applications Explained

PoE Standards

The original PoE standard, known as IEEE 802.3af, allowed 15.4 watts of power to be sent from a switch port. After cable resistance losses, each PD was guaranteed to receive at least 12.95 watts.In 2009, the IEEE 802.3at standard (also known as PoE+) was released, doubling the power per port to 30 watts. More recently, the new IEEE 802.3bt standard (PoE++) was formalized, allowing a massive 90 watts of power.

The Advantages of PoE Technology

Power over Ethernet (PoE) technology uses network cables to transmit data and power to devices. This means that a single cable can fully support devices such as wireless access points, VoIP phones, IP cameras and IP TV decoders.PoE eliminates the need for power cables and reduces cabling costs.The benefits of PoE include.

• Reduced infrastructure costs

Transmitting power and data over cables makes it much cheaper to install a PoE system compared to traditional wiring.PoE also allows for easier and cheaper outdoor installation.

• Safer than traditional outlets

PoE has fewer installation steps and fewer electrical hazards.PoE also reduces the risk of power outages, potential damage to equipment, and electrical overloads.

• Enhanced Flexibility

PoE power supplies and devices are plug-and-play and highly configurable. This makes it easy to add or remove devices without interrupting or disrupting the entire system.

• Flexible centralized management of networked devices

PoE-controlled devices can be disconnected and reconnected to a new PoE system with minimal downtime.PoE systems provide better control for smart buildings and ip-based security systems.

• Greater Scalability

PoE networks can be easily expanded when more devices need to be added in new locations.

What is the difference between IEEE 802.3 af and IEEE 802.3 at?

The difference is the amount of power that can be delivered. IEEE 802.3af supports 15.4 watts over Ethernet cables. IEEE 802.3at can deliver up to 30 watts over Ethernet cables.

How does Power over Ethernet work?

In PoE, Ethernet cables are used to transmit power to the device, and PoE devices require no additional wiring during installation. Initially, PoE was primarily used for Voice over Internet Protocol (VoIP) telephony, which allowed existing IP networks to carry voice data. As PoE became more popular, security cameras became one of the most abundant PoE devices on the market. Later, as wireless connectivity became ubiquitous, wireless access points entered the PoE world.

Does PoE need special Ethernet cable?

No. PoE uses standard Cat 5 Ethernet cables to deliver both power and data.

Do I need PoE or PoE+?

This depends entirely on the type and nature of the PoE device you want to use. The original PoE standard (IEEE 802.3af) allowed 15.4 watts to be sent from a switch port. Taking into account cable resistance, each device was guaranteed to receive at least 12.95 watts. The updated IEEE 802.3at standard (also known as PoE+) doubles the power per port to 30 watts.

Newly powered devices are taking advantage of this advancement and require more power than ever before. Even if your current devices only require the standard power of 802.3af, you should consider the types and requirements of devices you will add in the future.802. This may be a viable path to take!
