Why are communication fiber optic cables needed for photovoltaic projects at high-voltage substations
Fiber is more reliable than the wireless communications used in residential and small commercial solar installations. Utility-scale solar facilities are most commonly networked using fiber optic technology. The design is the same sort of point-to-point Ethernet technology based on single-mode fiber that's used in enterprises and industrial applications, as opposed to the Passive Optical Network (PON) approach used. But inside many of those cables runs another essential component: fiber optic cables high voltage systems that transform ordinary power lines into intelligent networks capable of real-time monitoring and control. They are particularly useful in large solar power plants where data needs to be transmitted across vast areas. Fiber's characteristic immunity to electrical interference and long-distance capability make it an essential.
