Today in our world change is slowly taking its place and in this case for cables as well. Conventional internet, telephone and LAN cables are bit by bit being replaced by glass cables sending data via light. Normally a copper wire would send information by electromagnetic current. At times though, they are affected by other sources of electricity such as lightning and other electromagnetic interference. Fiber Optics or Optical Fiber is faster, has higher bandwidths, less data loss over distance and will eventually replace copper wires wholly.
