The Applications of Phoenix Contact FL SWITCH 1105N-2SFP

1. Remote Pump Station Communication in Water Management

In a large water treatment network, pump stations are often scattered across vast areas. The FL SWITCH 1105N-2SFP provides stable fiber connections between these remote sites and the main control room. Its SFP uplinks enable long-distance communication resistant to electromagnetic interference, while QoS prioritization ensures that critical control data—like pump status and flow rates—arrives first. Its compact DIN-rail housing and wide temperature tolerance make it a reliable choice for outdoor or cabinet installations exposed to fluctuating conditions.

2. Railway Signaling and Vehicle Networking

Rail infrastructure relies on consistent data transfer between trackside systems and control centers. This switch’s dual SFP ports create high-speed, fiber-based links that remain stable even under heavy vibration and electrical noise. The energy-efficient Gigabit performance supports real-time signaling, CCTV feeds, and passenger information systems. Its robust polycarbonate enclosure and extended temperature range allow it to perform seamlessly inside locomotives, signal boxes, and maintenance depots without additional cooling equipment.

3. Factory Automation and Control Line Integration

In modern manufacturing plants, hundreds of controllers, drives, and sensors exchange data simultaneously. The FL SWITCH 1105N-2SFP simplifies connectivity between production zones using auto-negotiation and auto-crossing features that eliminate setup errors. Jumbo frame support enables smooth transmission of large data packets from vision systems and robots. By combining copper and fiber interfaces, it creates a scalable and interference-free backbone, ensuring every machine communicates efficiently across the entire production floor.

4. Traffic Monitoring and Intelligent Transport Systems

Urban traffic networks demand continuous data from roadside sensors, cameras, and signage. The FL SWITCH 1105N-2SFP ensures uninterrupted communication over long fiber links, even in environments with electrical noise or unstable power supply. Its low power draw supports solar-powered enclosures, and LED status indicators allow quick fault detection during field maintenance. This switch enhances reliability for real-time traffic analytics, signal control, and emergency management within smart transportation systems.
