Fiber optic systems are much more efficient than coaxial and copper mediums because there is far less loss of data. This can be attributed to the design of optical fibers and, more specifically, the principle of total internal reflection that they use. The cladding used in fiber optic systems also greatly increases the effectiveness of data transmission. Because of this innovation, coupled with the total internal reflection, there is no crosstalk between cables.

As the cost of materials continues to go down, fiber optic cabling is becoming more and more cost efficient. In some applications today, it is actually less expensive to use optical fibers than to use metal wire alternatives. Combine this with the fact that fiber optic systems need little or no maintenance or upgrading, and it is clear that fiber has already surpassed the cost parity with copper. Considering the higher performance, capacity, and efficiency that fiber technology holds over traditional wire systems, it is quite clear that fiber optics have a higher cost efficiency than metal alternatives.

Fiber optic systems are one of the safest forms of data transmission in terms of fire prevention. Metal wire forms of transmission can create sparks, causing shorts and in some cases, fire. Since optical fibers use light rather than electricity to carry signals, there is no chance of starting an electrical fire. This simple fact makes fiber optics an extremely safe form of wiring, especially when compared to more dangerous traditional wire alternatives.

The need for long-distance data transmission has been around since the beginnings of civilization. Today, fiber optic systems are one of the most reliable ways to accomplish this in a modern world. While the technology may be modern, its roots can be traced back throughout history. What started as smoke signals gradually turned into semaphore systems, and then telegraphs. These early communication systems possess the same qualities that are the basis of fiber communication systems.

Within the last century, the discovery that light could be passed through jets of water, and then glass tubes, has led to the modern developments which have given us the optical fibers we are familiar with today.

With every new day, the demand and use of optical fiber technology grows exceedingly fast. Telecommunication industries have made these technologies a cornerstone of technological proficiency. Fiber optics has found a solid place in data transmission networks, as well. Cable television companies now use fiber optic systems to deliver television programming to millions of households.

Intelligent transportation systems, such as smart highways with intelligent traffic lights, automated tollbooths, and changeable message signs also use fiber-optic-based telemetry systems. The biomedical industry has also found use for optical fiber. Fiber-optic systems are used in many modern telemedicine devices for transmission of digital diagnostic images in hospitals around the world. Other applications for optical fiber include space, military, automotive, and the industrial sector.
