Main Features: 1. Supports 10/100/1000Base-TX and 1000Base-/LX switching. 2. 2 x 1.25Gbps full-duplex fiber ports and 4 x 10/100/1000M Ethernet ports with auto-negotiation function. 3. Supports 1000M speed, /MDIX, and half/full-duplex with auto-negotiation function. 4. Each port has a complete LED indicator light. 5. Supports single mode single fiber, single mode dual fiber, multi-mode dual fiber, and SFP slot. 6. Supports IEEE802.1d Spanning Tree. 7. Supports high-performance function on each port. 8. Supports 5-12V voltage input. 9. Supports IEEE 802.3x flow control and backpressure control. 10. Requires no configuration and works directly when you start it. 11. Low power consumption with heatsink built-in for long-lasting efficient operation. It features 4 x 10/100/1000Mbps Ethernet ports and 2 x 1.25Gbps fiber ports. It uses Marvell chip for low power consumption and high stability. It extends the transmission distance of a network from 100m to 120km via copper cables. It can extend the transmission distance; there are also many other advantages such as isolation protection, good data security, working stability, and easy maintenance.
