2. Smart City Infrastructure (Traffic Management Systems)

Connecting traffic light controllers, surveillance cameras, and sensor networks at intersections or along roadways for intelligent transportation systems.

Problem Solved

Provides robust and secure data transmission for real-time traffic monitoring and control in outdoor cabinets (protected from direct water, but exposed to dust and temperature swings) using multi-mode fiber for longer distances between intersections and copper for local device connections, powered by diverse DC sources.

3. Process Control in Utility Substations

Establishing a dependable communication backbone for monitoring and controlling intelligent electronic devices (IEDs) in power utility substations.

Problem Solved

Offers a hardened network switch compliant with industrial standards (e.g., IEC 61850-3 mentioned for Moxa products) capable of operating in a wide temperature range and handling DC power fluctuations, ensuring secure and redundant data flow for critical power grid operations. The fiber optic ports allow for interference-free communication over longer distances within the substation.
