There are many advantages of using fiber over coax systems and free space. One major advantage is eliminating the problem of bandwidth allocation. Frequency assignments are allocated by the FCC for all communication ranges and the FCC will regulate everything from modulation techniques and EMI limits. With fiber optics these problem are eliminated. Another advantage of fiber optics is the high bandwidth available with low attenuation. From the time fiber optic networks were developed, attenuation dropped from 1000 dB/km to less than 0.16 dB/km. With this drop of attenuation, fewer repeaters were needed. Because of the cost reduction of using less repeaters fiber optics could be more efficient due to the longer distance spans repeaters could be placed. A fiber medium will also eliminate external electromagnetic fields. Without an Electromagnetic Field, crosstalk can be completely eliminated and multiple fibers can easily be bundled up together. Having the Electromagnetic......
