Fire and explosion protection measures for optical cables
Practical safety measures include using certified fiber-optic interfaces, housing connectors in explosion-proof enclosures, and routing fibers in conduit or armored cable to protect them and contain any escape light. Optical fibers are commonly used for data transmission in industrial environments, particularly when cable runs exceed 100 meters and copper Ethernet is no longer viable. The general assumption is simple: once installed, the cable does its job – transmitting data from point A to B – and that's it. Its ability to provide continuous temperature readings over long distances makes it an ideal solution for fire detection in tunnels. While fiber optics eliminate electrical ignition sources, fiber cables still require proper safety measures in explosive atmospheres. For instance, a broken. e National Electrical Code (NFPA 70). FLS believes that outdoor cable should not be installed within buildings in lengths greater than 50 feet if it does ot meet the requirements of NFPA 70. These cables guarantee uninterrupted communication during emergencies, thereby reducing risks to occupants.
