The FL-DUG0101-SC20A/B is a 10/100/1000Mbps unmanaged industrial Ethernet switch equipped with 1 Gigabit RJ45 port and 1 SC-type single-mode optical port, supporting transmission distances up to 20 kilometers. Designed specifically for use in industrial automation, transportation systems, security monitoring, and remote IoT deployments, this device ensures stable communication over fiber optics where electromagnetic interference or long-distance transmission challenges exist.
The SC port uses a single-fiber, bidirectional (WDM) transmission mechanism, with FL-DUG0101-SC20A and FL-DUG0101-SC20B used as a complementary pair—each operating at different wavelengths (Tx1310nm/Rx1550nm and vice versa) to enable full-duplex communication over a single fiber core.
Its industrial-grade metal housing ensures high durability, with support for -40°C to +75°C wide temperature operation and strong EMI resistance. Installation is made easy with DIN-rail mounting, and its fanless design ensures silent operation with low power consumption.
The switch supports 12~48V DC redundant power inputs for power backup in mission-critical applications. The Plug-and-Play nature simplifies deployment, and no configuration is required. Whether in outdoor camera poles, roadside cabinets, substations, or factory control rooms, the FL-DUG0101-SC20A/B is a reliable solution for fiber-to-the-edge industrial network designs.
