LevelOne RJ45 na SFP Gigabit mediálny konvertor, PoE PSE

The LevelOne GVT-2012 Gigabit Media Converter is a single-port, end-span IEEE 802.3at High Power over Ethernet (PoE+) converter with a Gigabit SFP port for fiber connectivity. It delivers both data and up to IEEE 802.3at power over the RJ45 interface, enabling connection of higher-power network devices such as PTZ network cameras, PTZ speed domes, color touch-screen VoIP phones and multi-channel wireless LAN access points without requiring additional electrical cabling. The converter supports 10/100/1000Base-T on the copper side and 1000Base-LX/SX via SFP on the fiber side, and is CE and RoHS compliant.

Advantages

The GVT-2012 integrates Gigabit data transfer with IEEE 802.3at high-power PoE delivery in a compact unit, reducing the need for separate power supplies and extra wiring. Its SFP fiber port enables flexible fiber link options (1000Base-LX/SX) while the single RJ45 port provides up to 1000 Mbit/s copper connectivity. With a small footprint and an MTBF around 30,000 hours, it is suitable for deployments that require reliable wired connectivity and centralized power delivery.

Suitable for

• PTZ network cameras and PTZ speed dome cameras
• Color touch-screen VoIP telephones
• Multi-channel (IEEE 802.11a/b/g/n) wireless LAN access points
• Other network devices requiring IEEE 802.3at power over Ethernet

How to use

Install the GVT-2012 near the network fiber run and insert a compatible SFP module into the SFP slot, then connect the fiber cable to the module. Connect the powered device (PD) to the RJ45 port using standard Ethernet cabling. Provide the required 48–57 V DC input to the converter per installation instructions. Once powered, the converter will forward Gigabit data between the fiber and copper interfaces and supply IEEE 802.3at power to the connected PD through the RJ45 port.

Recommendations

Use compatible SFP modules and fiber types (LX for single-mode, SX for multi-mode) and ensure the connected devices support IEEE 802.3at PoE+. Verify the input voltage range (48–57 V) and follow site cabling best practices to maintain reliable data and power delivery.
