Information carried in the form of light provides a vast array of features and benefits. _x000D__x000D_Superior Transmission Distance_x000D_It is not unusual for optical systems to go over 100 kilometres (km), or about 62 miles. _x000D__x000D_Enhanced Security_x000D_It is impossible to remotely detect a signal being transmitted within a fibre cable. The only way to do so is by actually accessing the optical fibre itself. This makes fibre extremely attractive to governmental bodies, banks and other businesses with major security concerns._x000D__x000D_No Metallic Components_x000D_Fibre optic cable can be installed in areas with electromagnetic interference (EMI). This includes areas around utility lines, power-carrying lines and railroad tracks. Fibre is also ideal for areas of high lightning-strike incidence.
