Advantages of Optical Fiber

Fiber optic cables have a much greater bandwidth than metal cables. The amount of information that can be transmitted per unit time of fiber over other transmission media is its most significant advantage. An optical fiber offers low power loss, which allows for longer transmission distances. In comparison to copper, in a network, the longest recommended copper distance is 100m while with fiber, it is 2km. Fiber optic cables are immune to electromagnetic interference. In comparison to copper, a fiber optic cable has nearly 4.5 times as much capacity as the wire cable has and a cross-sectional area that is 30 times less. Fiber optic cables are much thinner and lighter than metal wires. Optical fibers are difficult to tap. As they do not radiate electromagnetic energy, emissions cannot be intercepted. It is flexible, bends easily and resists most corrosive elements that attack copper cable.

Disadvantages of Optical Fiber

The optical fibers are difficult to splice, and there are loss of the light in the fiber due to scattering. They have limited physical arc of cables. The optical fibers are more expensive to install, and they have to be installed by the specialists. The fiber optic cable is a small and compact cable, and it is highly susceptible to becoming cut or damaged during installation or construction activities. The fiber optic cables can provide tremendous data transmission capabilities. The fibers can be broken or have transmission losses when wrapped around curves of only a few centimeters radius.
