What Is Fiber Optics Technology?
Fiber optics is a technology that uses glass (or plastic) threads, called fibers to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. Over metal cables, fiber optics provide a much greater bandwidth to carry more data, they are are less susceptible than metal cables to interference, they are thinner and lighter than metal wires, and most importantly data can be transmitted digitally (the natural form for computer data) through the use of fiber optics. Like all technologies, fiber optics has its downside. The cost of fiber optic cable is more than metal cable, making the cost for installation much greater. In addition they are more fragile than wire and are difficult to split. Fiber optics is a particularly popular technology for local-area networks. Telephone companies are steadily replacing traditional telephone lines with fiber optic cables. In the future, almost all communications w
