Subjective Question Answer What are the advantages of optical fiber

The advantages of Optical fiber are:

It can handle much higher bandwidth than copper. Due to the low attenuation, repeaters are needed only about every 30 km on fiber lines versus about every 5 km for copper.
Fiber is not affected by power surges, electromagnetic interference or power failures. It is not even affected by corrosive chemicals in the air, making it ideal for factory environments where electrical interference is very high.
Fiber cable is lighter than copper cable. One thousand twisted pair copper cables of 1 km long weigh 8000 kg. But fibers have more capacity and weigh only 100 kg, which greatly reduces the need for expensive mechanical support systems that must be maintained.
Fibers do not leak light and are quite difficult to top. This gives them excellent security against potential wire-tappers.
