Fiber optics have no electrical current, but the 'light' in a fiber optic cable could have enough energy to create an ignition or spark in an ATEX hazardous area. This can be very dangerous, because a spark could ignite a flame or even an explosion. 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. Note that Recommendation ITU-T L. 0, in February. – refers to single-mode optical fibre cables installed by the pulling method to be used for telecommunication networks in ducts and tunnels; – recommends that optical fibre dimensional and transmission characteristics should comply with one or more of [ITU-T G.
