WHY FIBER OPTICS?
The reasons are as follows:
FIBER OPTIC SYSTEMS PROVIDE:
1. Immunity to electromagnetic fields.
This means that the fiber optic cables can be installed in areas of high electromagnetic fields without any appreciable effect on the integrity of the data sent and received. The fiber-optic cable can be laced to a power cable without any worry of signal degradation due to inducted electrical fields.
2. Immunity to data loss or interference due to lightning strikes.
Because the fiber-optic cable is glass, a non-conductor of electrical energy, the adverse effects of lightning on fiber-optic cable is eliminated. Direct buried fiber-optic cable will not be affected by lightning potentials in the area, as are copper cables.
3. Immunity to ground loops.
Ground loops, an unequal electrical potential between two or more grounds, can cause communication systems to have large data errors. Again, since fiber-optic cable is a non-conductor, the grounds are never connected and eliminate ground loop problems completely.
The bottom line is, of course, that data transmitted and received, using fiber-optic methods, has a much greater confidence factor than with electronic or standard tone systems.
