Unlike copper wiring, fiber optics do not conduct electricity and therefore cannot produce sparks or arcs that could ignite a flammable atmosphere. Similarly, we don't think about personal or property damage due to fire because it isn't a source of heat Understanding the safety hazards that go with fiber optic cable is critical for those who install or maintain. A CATV operator running a 144-fiber cable with approximately one-third of those fibers carrying 20 dBm of EDFA-amplified optical power experienced a fire when the cable was cut at a service loop. The EDFA remained active throughout. Today, fiber-optic connectivity has emerged. Also, some specialized vendors have developed fiber optics (FO) cables/connectors for hazardous areas. They are not intrinsically safe. Fiber optics cables may not have that high voltage/current in copper wires. 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.
