In order to understand the differences between the two more intuitively, the following will compare them from multiple dimensions:
Characteristics | Non-PoE Switch | PoE Switch |
Function | Data transmission only | Data transmission + power supply |
Cost | Lower | Higher |
Wiring Complexity | Requires additional power cable | Just one Ethernet cable |
Application Scenarios | General network environment | Surveillance, wireless AP, IP phones, and other scenarios requiring power supply |
Power Support | None | Supports 15.4W to 90W (depending on standards) |
Deployment Flexibility | Limited by power outlet location | Can be deployed in areas without power sources |
Management Features | Both unmanaged and managed types | Usually managed, supports power management |
8. Application Scenarios
Non-PoE Switch
Non-PoE Switches are widely used in network environments that do not require power supply:
- Home Network: Connect computers, smart TVs, gaming consoles, and other devices to meet daily internet access needs.
- Small Office: Provide network connections for employee computers, printers, and servers, supporting small LANs.
- Data Center: In server clusters, Non-PoE Switches are used for high-speed data transmission, usually as managed switches.
For example, in a home network, an 8-port gigabit Non-PoE unmanaged switch can easily connect a router, NAS storage devices, and multiple computers, satisfying high-definition video streaming and file sharing requirements.
PoE Switch
PoE Switches are mainly used in scenarios where data and power need to be transmitted simultaneously:
- Video Surveillance System: PoE Switches supply power and transmit video data to IP cameras, suitable for malls, campuses, factories, and other places.
- Wireless Network Coverage: Power wireless access points (APs), supporting large-scale Wi-Fi coverage in enterprises or public places.
- VoIP Phone System: Provide power and network connection for IP phones, simplifying enterprise communication network deployment.
- Smart Buildings: Power smart lighting, sensors, and other IoT devices, promoting smart city development.
Taking a small to medium-sized enterprise surveillance system as an example, an 8-port PoE Switch can connect multiple high-definition IP cameras. Each camera can transmit data and be powered through a single Ethernet cable, eliminating the need for complicated power wiring, and supporting remote management for easy maintenance.
