    Gigabit Ethernet Network Media Converter 10/100/1000Base-T RJ45 to 1000Base-X SFP Slot PoE Media Converter

     

    The PoE Gigabit Ethernet Media Converter extends transmission distance by copper (CATx/UTP)-to-fiber connection. Furthermore, it can supply more than 30 watts of power and a 1Gbps data connection by using an ethernet cable. The poe media converter is designed to satisfy the growing demand for high-power required network equipment such as cameras, Wifi access points, etc. The PoE Gigabit Ethernet Media Converter is an ideal solution to deliver data and power network devices directly via the RJ45 interface without the need to install extra power outlets and electrical cabling.

     

    The media converters are compatible with a wide range of SFP transceivers, such as 100Base SFP, 1G BIDI SFP, 1G CWDM SFP, 1G DWDM SFP transceiver modules, etc. Furthermore, QSFPTEK also provides other versions of 1g media converter with built-in optical modules, the transmission distance is from 2km to 40km, and LC or SC connector types can be selected.

      I accidentally visited their website and after reading their basic information, I chose to trust and placed an order for this transceiver. The delivery was fast, the account manager's response was always timely, and the product quality was also very good.

      I connected my switch to the surveillance devices using this PoE media converter, and it directly powers the devices. They are simply plug-and-play, which significantly improves my work efficiency. The individual power supply of 30W meets the power requirements of my surveillance devices perfectly. It's fantastic!
