Industrial 4-Port Gigabit Ethernet Switch with 20km Fiber Uplink
This pocket-sized industrial Ethernet switch delivers robust connectivity and remarkable power flexibility in a compact, hardened design. It features a Gigabit port that can receive IEEE 802.3at/bt PoE for its primary power, alongside two 10/100/1000BASE-T RJ45 ports with DC 5-24V power output to connected devices. The switch is engineered for long-distance network extension with a built-in 1000BASE-X 20km single-mode SC fiber optic uplink, enabling reliable data transmission over vast distances. Its combination of a small footprint, wide-range power options, and industrial-grade durability makes it the ideal all-in-one solution for space-constrained and remote applications, from factory automation to outdoor telecommunications.

Industrial-Grade 4-Port Switch: 3x 10/100/1000T RJ45 & 1x Gigabit 20km SC Fiber
This industrial-grade 4-port switch is engineered for mission-critical connectivity in harsh environments, reliably operating in temperatures from -30 to +70°C. It consolidates local device networking and long-distance backbone links into a single, robust unit, featuring three 10/100/1000BASE-T RJ45 ports for connecting field devices and one Gigabit 20km SC fiber port for a stable, high-bandwidth uplink over extended distances. With a wide-range 2x DC 12-48V power input for redundancy and flexibility, this compact yet powerful switch delivers the resilience and performance required for industrial automation, traffic control, and outdoor network applications.
