What is the main advantage of using PoE?

• A. Transmits data at higher speeds
• B. Reduces cabling costs
• C. Allows transmission of data and power over the same cable
• D. Increases network security

Answer: (C)

The main advantage of using Power over Ethernet (PoE) is that it allows the transmission of data and power over the same cable. This innovative technology simplifies network installations by eliminating the need for separate power sources for devices like IP cameras, wireless access points, and VoIP phones. By integrating power delivery into the data cable, PoE reduces clutter and enhances flexibility in device placement, allowing for easier adjustments and installations in various environments. This capability is particularly beneficial in scenarios where having a power outlet nearby is impractical or impossible. Consequently, the ability to use a single network cable for both power and data streamlines overall network infrastructure, ultimately leading to lower installation costs and increased efficiency in device management.
