Country: France
Application Site: Tunnel Enclosure
A tunnel system requires extensive infrastructural planning, including the integration of a network transmission system to ensure clear and reliable communication. This was the case of a tunnel project in France, since the project needed a comprehensive industrial networking solution. They have a surface-level access control system managed through their software to manage Wi-Fi communication, alarm enclosures, and blast detection. Having a network in a tunnel also requires that any device withstand environmental factors that could affect its performance. It also included a badge-counting feature with a Bluetooth antenna to identify the number of people inside and their locations, facilitating the deployment of emergency services in case of fire, explosion, or other incidents.
◆ High-Power PoE and 10G Uplink for Core Backbone
The IGS-10020HPT provides up to 240W PoE power for devices like cameras and Wi-Fi APs, with dual 10G SFP+ uplinks for fast data flow, perfect for emergency response. The IGS-6325-8T8S4X adds Layer 3 routing, high port density with Gigabit and 10G slots, ITU-T G.8032 ERPS (Ethernet Ring Protection Switching) technology, and redundant power for robust reliability. Both withstand -40 to 75°C temperatures and offer surge protection, ensuring stable operation in tunnel environments.
◆ PoE Switch for Edge Devices
The GSW-1820HP offers 16 PoE+ ports with a 300W budget for connecting edge devices like cameras, alarms, sensors, etc. It delivers 36Gbps switching capacity and energy-saving features, making it efficient for intelligent surveillance PoE applications.
◆ Long-Range Fiber Connectivity
Installed for stable long-distance transmission up to 10km, the MTB-TLR ensures seamless fiber links between switches across the tunnel infrastructure.
