The switch supports PoE extension

Yes, many modern PoE switches support PoE extension, allowing power and data transmission beyond the standard 100-meter Ethernet limit.

Standard Po

E Limitations

Typical PoE (IEEE 802. 3af/at) delivers power and data over Ethernet cables up to 100 meters (328 feet). Beyond this distance, signal degradation, voltage drop, and reduced data rates occur, which can affect device performance.

Po

E Extension Features

To overcome distance limitations, some switches include Extend Mode or long-range PoE capabilities: Extend Mode / Long-Range PoE: Switches can transmit PoE up to 200–500 meters, though the data rate is often reduced to 10 Mbps per port for extended distances.

DI

P Switch Configuration: Certain models, like Edimax Long Range PoE+ switches, allow users to select which ports operate in Extend Mode, extending PoE up to 200 meters while maintaining standard speeds on other ports.

VLAN and CCT

V Modes: Some switches use VLAN or CCTV modes to isolate extended PoE ports, improving network efficiency and security for remote devices. Practical ExamplesTP-Link TL-SG1005P: Supports Extend Mode for powering cameras and access points over longer distances, simplifying deployment without additional power lines.

TREN

Dnet Long-

Range PoE+ Switches: Extend PoE signals up to 656 feet (200 meters) with reduced speed, suitable for access points, VoIP phones, and IP cameras. Edimax Long Range PoE+ Series: Offers flexible port-based Extend Mode, allowing up to 200 meters of PoE transmission at 10 Mbps, while other ports maintain full-speed connectivity.

Considerations

Reduced Data Rate: Extended PoE distances typically lower the port speed to 10 Mbps, which is sufficient for low-bandwidth devices like IP cameras but may not suit high-speed applications. Power Budget: Ensure the switch's total PoE budget can support all connected devices at extended distances, as longer cables increase power loss. Device Compatibility: Verify that connected devices support PoE and can operate at the reduced speed if using extended distances.

In summary, if your switch advertises Extend Mode, long-range PoE, or DIP switch-based PoE extension, it can support PoE extension beyond 100 meters, making it suitable for powering remote devices without additional electrical infrastructure.
