Optical interface operates at 100 Mbps Ethernet rate for reliable fiber side connections. Electrical interface autonegotiates to 10 Mbps or 100 Mbps Ethernet rate, enabling seamless integration with a wide range of switches, routers, and devices without manual speed configuration. Environmentally hardened to operate in extreme temperatures, providing dependable performance in harsh industrial and outdoor environments. LED indicators give ataglance confirmation of operation, link status, and activity, aiding quick diagnostics and monitoring. Designed for robust field deployment with a focus on dependable function, simple integration, and consistent performance in demanding conditions. Use scenarios Industrial automation site: Connect a fiber backbone to copper Ethernet equipment on the factory floor where temperature varies and reliability is critical, ensuring uninterrupted data flow between control systems and sensors. Outdoor telecom or utility installation: Deploy at remote sites exposed to weather and temperature swings, using the ruggedized construction to maintain stable Ethernet connections between field devices and core networks. Data center edge or campus networking: Use at the network edge to bridge optical links to Ethernetenabled servers, storage, or switches, with autonegotiation simplifying setup and reducing configuration steps.
