Buy 1783-US6T2H now for ultra-long distance fiber networking
The Allen-Bradley 1783-US6T2H is a specialized unmanaged Ethernet switch from the Stratix 2000 series, engineered for extreme distance and high-noise industrial environments. By incorporating single-mode fiber optic capabilities alongside standard copper ports, this device enables automation engineers to seamlessly link isolated machinery over vast distances—up to tens of kilometers—without sacrificing the plug-and-play simplicity of an unmanaged architecture.
Technical Specifications
- Total Ports: Eight (8) active ports.
- Port Configuration: Six (6) 10/100 Mbps copper ports and two (2) 100 Mbps single-mode fiber optic ports.
- Input Voltage: 18-30V DC (Nominal 24V DC).
- Switch Type: Unmanaged, plug-and-play.
- Optical Mode: Single-mode transmission (ideal for long distances).
- Product Lifecycle: Discontinued as of June 2025 (legacy support available).
Comprehensive Technical Overview
Standard copper Ethernet is strictly limited to 100 meters, and even multimode fiber generally maxes out around 2 kilometers. The true power of the 1783-US6T2H lies in its two single-mode fiber ports.
