With Power over Ethernet (PoE) controllers, designers can send data and electrical current via a single Ethernet connection. Batteries, local power adapters, and additional power cabling are not required because remote devices are powered over an Ethernet cable connection. Two kinds of PoE controllers are the bridge rectifier known as N+1 and O-Ring.
Any standards or ad hoc methods that enable the transfer of electricity and data via an Ethernet cable are referred to as "power over Ethernet," or simply "PoE." By merging both processes into a single line, often an RJ-45 cable reduces the amount of cable clutter.
Significance of PMIC - Power Over Ethernet (PoE) Controllers
The significance of PMIC- Power Over Ethernet (PoE) Controllers is that they use Ethernet data cables instead of conventional electrical power cords and wiring; power over Ethernet (PoE), a technology for constructing wired Ethernet local area networks (LANs), allows the electrical current required to operate each device.
PoE is a less expensive method of Ethernet cabling, which can carry both power and data, rather than electrical wiring, which only gives power and necessitates separate wiring for data. PoE is used in both smart home applications and commercial settings.
Difference Between Power Over Ethernet (PoE) and Power Over Ethernet Plus (PoE+)
The key difference between PoE and PoE+ is the amount of power given. PoE allows 15.4 watts over the Cat5 line, although PoE+ can supply up to 30 watts over the same Cat5 line with 25.5 watts supplied to the device.
Benefits of PoE
The following are some major benefits offered by PoEs:
- Easy to install
- They are cost-effective
- Higher data transfer speed
- More secure
Types of Power Over Ethernet PoE
There are two basic types of PoE used according to their functionality and purpose, which are given below:
- Power devices Power Over Ethernet (PD PoE) - are the devices that utilize energy supplied through the connection together with WAPs (Wireless Access Points), IP (Internet Protocol) cameras, VoIP Voice (Over Internet Protocol) phones, Public address systems, intercoms, Network Adapters (NDs)a, and more compatible devices.
- Power Sourcing Equipment (PSE PoE) - is the method that acts as an energy resource for the connections. This could be a network switch, also known as an end span, or it could be a midspan device, which acts as a bridge between a non-PoE switch and a PoE device.
Applications of Power Over Ethernet (PoE)
Devices that consume 15.4- 30 watts (W) or less power support PoEs, such as:
- LCDs (Liquid Crystal Display Screens) and large TVs
- Zoom Robotic Cameras
- Wireless AP devices or Nodes
- Video Telephones
- Remote Computer Terminals
- Computer Monitors
- Laptops
- Thin Client Computers,
- Door Access Systems,
- Video Signing Displays
- Network Audio
