IP cameras, wireless access points, VoIP phones, access control devices, network expansion, PoE network installationsOverview:
The Cudy POE40 4-Port Gigabit PoE++ Extender provides a practical way to extend both network data and PoE power beyond the usual 100-metre Ethernet distance. It accepts a single 802.3bt, 802.3at or 802.3af PoE input through Port 5 and distributes the connection across four Gigabit PoE output ports. This makes it suitable for IP cameras, wireless access points, VoIP phones, access control readers and other powered network devices that need to be installed farther from the main network switch.
Description:
The Cudy POE40 is designed for installations where one upstream PoE connection needs to supply multiple powered devices. Each of the four output ports can provide up to 30W, with a maximum distribution of either two 30W devices or four devices receiving up to 12.95W each. In standard mode, connected devices can operate over distances of up to 100 metres at Gigabit Ethernet speeds.
For longer cable runs, Extend mode increases the transmission distance to up to 250 metres using Cat 5e or better network cable. This mode is intended for extended installations where speed requirements are lower, with network speed limited to 10 Mbps. VLAN mode can also isolate the four downstream ports from each other, helping improve network separation and security.
The built-in PoE Watchdog adds another layer of reliability by monitoring connected devices and automatically restoring power when an unresponsive PoE client is detected. For larger installations, up to three Cudy POE40 units can be daisy-chained to achieve greater network reach.
Features:
Gigabit PoE++ Extension for Network Devices
The Cudy POE40 combines PoE power distribution with Ethernet extension in a compact enclosure. A single PoE connection from the upstream network can be divided between four downstream PoE ports, reducing the need for additional power supplies at the remote location.
It supports common PoE standards, making it suitable for a range of compatible network equipment:
- 1x Gigabit PoE input supporting 802.3bt, 802.3at and 802.3af
- 4x Gigabit PoE output ports supporting 802.3at and 802.3af
- Up to 30W available from an individual output port
- Maximum output of 2x 30W or 4x 12.95W across the four ports
- Standard transmission distance of up to 100 metres at Gigabit speeds
- Extend mode supports distances of up to 250 metres at 10 Mbps
- Compatible with Cat 5e or higher network cable
Reliable PoE Protection and Network Operation
For installations where network equipment needs dependable power delivery, the POE40 includes multiple protection measures. These help protect connected hardware against common electrical and environmental risks while supporting stable operation.
Protection includes polarity protection, overvoltage protection, short-circuit protection and automatic voltage regulation. The unit also provides 6kV lightning and surge protection, 6kV ESD contact protection and 8kV ESD air protection.
The PoE Watchdog function continuously monitors connected devices and can automatically recover devices that stop responding, reducing the need for manual intervention.
Flexible Installation for Cameras, WiFi and VoIP
The Cudy POE40 is well suited to installations where several PoE devices need to be positioned away from the primary network switch. It can be used with IP surveillance cameras, wireless access points, VoIP telephones, access readers and other compatible PoE network equipment.
VLAN mode provides additional isolation between downstream ports, which can be useful where connected devices should remain separated from one another. The ability to daisy-chain up to three POE40 extenders also provides greater flexibility for larger network layouts.
The durable all-metal housing allows the extender to be installed on a desktop or mounted on a wall, making it suitable for offices, security installations, commercial premises and other network environments.
