The most common analogy to explain the difference between copper cable and fiber optics is to compare copper wire as a two-lane highway and fiber optics as a freeway. More traffic. Higher speed.Instead of electrical signals (copper), fiber optics speeds data over long distances through an insulated glass fiber material. Single line, voice-grade copper can only travel about 1.2 miles without repeaters. Optical systems can travel about 62 miles without processing.
Fiber optics cable provides more bandwidth yet is smaller. It has much more capacity but it easier to (physically) install. It comes in longer lengths - up to 12 km. That allows for faster, more economical installation.
Fiber is safer because it's non-conductive. It can be used in areas with high electromagnetic interference (such as power lines and radio waves). If a fiber optics cable breaks, it does not cause a potentially dangerous spark.
Fiber is much more secure. It's impossible to remotely detect the signal being transmitted within the cable.
Fiber Optics systems are more 'manageable' and can allow your organization to achieve significant productivity gains.
