Fiber Optics is a datacommunications technology that has revolutionized data transfer. The advantages of light as a data transmission medium were apparent even in the time of Alexander Graham Bell. A suitable conduit had to be found, and this came to fruition in the form of the optical fiber.
In principal, fiber optics serves the same purpose as copper wire by moving information from one place to another. However, the transmission medium is light, and that light is carried within a hair-thin optical fiber via the process of total internal reflection.
Advantages of fiber optics include:
With the advent of the internet, the need for fiber optics has become especially acute. The current boom in fiber optics companies is a direct result of the high bandwidth required by internet data, especially graphical data. The list of applications continues to grow.
- High data transmission rates and bandwidth.
- Low losses.
- Small cable size and weight.
- Immunity to EMI (both with respect to susceptibility and emissions).
- Safety due to lack of sparks.
- Data security.
