Fiber optic cable: much more convenient
A fiber optic cable has a number of advantages over a metal cable. Comprising a set of glass threads or plastic fibers that can each transmit messages modulated onto light waves, a fiber optic cable possesses larger bandwidth than its metallic counterparts. And the more the bandwidth the more the data. These cables are more convenient for users as they are much lighter and thinner than metal wires. Moreover, they are less susceptible to interference. With a fiber optic cable, you can transmit data digitally instead of analogically.
With more advanced technology, a fiber optic cable presently is capable of carrying a signal to a distance of about 60 miles. When it covers such a long distance, there is an equipment hut every 40 to 60 miles. The hut contains equipment that picks up and relays the signal to the next segment without losing any strength. But a fiber optic cable is more expensive than metal cables. Furthermore, they are more fragile than wire and are not easy to splice.
A fiber optic cable is particularly suitable for LANs or local area networks. Over the years, more and more telephone companies are switching over to fiber optic cables replacing traditional telephone lines. Optical fibers also play a major role in making the Internet available all across the world. For long distance calls and Internet traffic, it lowers costs considerably. There is little doubt that the use of such cables can only increase in the future.
