The IP Network Extender is a versatile device that enables long-distance transmission of IP-based data over existing coaxial cable infrastructure. It leverages EoC technology to extend network connectivity up to 500 meters using standard 75-5 coaxial cables while maintaining 100Mbps transmission speed. This extender features both RJ45 and BNC (Q9) interfaces, allowing seamless integration between modern IP networks and traditional coaxial systems. It operates effectively across industrial temperature ranges (-5℃ to +70℃) without requiring configuration. Ideal for modernizing legacy surveillance systems, industrial networks, and building automation, it provides a cost-effective solution for repurposing existing coaxial wiring to extend IP network coverage.
