Product Description Read full descriptionHide description
The KONGIA KG-FMC-1G-SFP-POE carries data over optical fiber and provides Ethernet connectivity and PoE power to a remote device. Includes an SFP slot of 1.25 Gb/s and an RJ45 10/100/1000 Mbps port compatible with IEEE 802.3af/at. Its RJ45 port supplies up to 25.5 W of PoE power.
The SFP is purchased separately to match fiber, connector, wavelength and distance. Supports single-fiber single-mode, dual-fiber single-mode or dual-fiber multimode links using the appropriate transceiver. The copper segment reaches up to 100 m with Cat.5e or higher; optical reach is determined by the SFP and link budget.
Offers speed and duplex autonegotiation, Auto MDI/MDI-X, IEEE 802.3x flow control and back pressure. Store-and-forward switching operates at wire speed, with a 2K MAC table, jumbo frames up to 9 Kbytes and latency ≤ 150 μs. Installation is Plug & Play, with no configuration.
The black metal housing measures 94 × 70 × 26 mm, weighs 0.15 kg and uses fanless side heat dissipation. Operates on 48–57 V DC and includes a 52 V / 0.7 A adapter with 100–240 V AC input and Chinese plug; US or European plugs are offered as options. The device's own consumption of 0.75–2 W is presented separately from the PoE load.
Recommended Applications
Remote access point
Connect a compatible PoE access point where fiber terminates and there is no switch beside the device.
Inter-building link
Integrate a surveillance or monitoring point using SFP modules and fiber compatible with both ends of the link.
Non-PoE Ethernet equipment
Connect a computer or other device to the RJ45 port for data. It has only one RJ45 port: multiple devices require an additional switch.
Camera with separate power supply
Use a compatible PoE splitter, purchased separately, for a non-PoE camera; check output voltage and power before connection.
