Feature:1. Long Distance Transmission: When used with different types of SFP modules, the FX port can be hot swapped to extend the fiber distance to 0 to 120km, supporting jumbo frame size of 9K bytes supports an operating temperature range of 0C to 60C.2. RJ45 Network Port: Fiber transceiver provides multiple Gigabit SFP optical ports and 10 or 100M adaptive RJ45 network port, users can choose different SFP optical modules according to field needs.3. Efficient Transmission: Fiber media converter supports lossless and efficient data transmission of multiple protocols, full and half duplex adaptive, IEEE802.3x flows control, backpressure flows control, multicast and QoS to ensure efficient network operation.4. LED Indicators: Easy to view LED indicators provide status to easily monitor network activity, compliant with IEEE 802.3 or 802.3u or 802.3af. TX, FX LINK or ACT, POWER, FDX status LEDs allow easy monitoring of network status.5. Plug and Play: Ethernet fiber switch plug and play, support MDI, MDI X port auto flip, no need to set up, plug in power, fiber, network can be used, easy to use.Specification:Item Type: SFP Fiber Media ConverterMaterial: MetalSupported Protocols: IEEE 802.3i IEEE 802.3u IEEE 802.3ab IEEE 802.3zOptical Port: 1Electrical Port: 4Data Rate: Optical Port 100mbps, Electrical Port 10 or 100Mbps.Package List:1 x Fiber Transceiver1 x Power Adapter1 x User Manual
