DMC-300SC Use Case
Industrial Ethernet Extension for Factory Automation over Multi-Mode Fiber
In a high-EMI manufacturing plant, the DMC-300SC-D-Link 1-port 10/100M to 100BASE-FX photoelectric converter (multi-mode, SC interface, 1310 nm) provides interference-free connectivity between PLCs and SCADA systems across 2 km. Deployed alone or paired with a DMC-1100 at the distribution switch, it ensures deterministic data delivery and minimizes downtime. Outcome: reliable network uptime, simplified fiber deployment and enhanced process control.
Campus Backbone Link for University Buildings Using 1310 nm Media Conversion
To overcome copper’s 100 m limit, campus IT teams use the DMC-300SC-D-Link converter as a standalone fiber uplink between academic blocks up to 1.8 km apart. When aggregated via a DMC-1100 in the main data center, it delivers secure, high-speed 10/100M Ethernet backhaul over multi-mode fiber. Outcome: seamless network expansion, cost-effective infrastructure and centralized management.
Long-Range IP CCTV Connectivity for Secure Perimeter Surveillance
Security integrators connect remote IP cameras to the NVR over 2 km of multi-mode fiber using DMC-300SC-D-Link’s 100BASE-FX SC interface at 1310 nm. Coupled with a DMC-1100 at the control room, the solution provides plug-and-play power-over-Ethernet support and low-latency video streaming. Outcome: crystal-clear video, robust link immunity and streamlined installation for critical surveillance.
