Today, the demand for data bandwidth is ever increasing, resulting in the phenomenal growth of the Internet. This resurrected the move to optical networking as the focus of new technologies. Currently, nearly half a billion people have Internet access and use it regularly. The important factor in these developments is the increase in fiber transmission capacity, which has grown immensely in the last decade. Because of fiber optic technology’s immense potential bandwidth, there are extraordinary possibilities for future fiber optic applications. Already, the push to bring broadband services, including data, audio, and video, has been underway, becoming available to both businesses and private homes.

Fiber Optic lines are strands of optically pure glass as thin as a human hair, that transmit infrared light, which carry digital information over a distance. Fiber Optics has many advantages over conventional copper and coaxial lines such as:
- Less expensive - Several miles of optical cable can be made cheaper than equivalent lengths of copper wire.
- Size - Optical fibers are made at smaller diameters than copper wire.
- Higher carrying capacity – One optical fiber can carry more information than many larger copper cables.
- Safety - Because no electricity is passed through optical fibers, there is no fire hazard.
- Speed - Fiber optic networks operate at high speeds - up into the gigabits.
- Bandwidth - larger information carrying capacity.
- Distance - Signals can be transmitted further without needing to be strengthened.
- Resistance - Greater resistance to electromagnetic noise and signal degradation.
- Maintenance - Fiber optic cables costs much less to maintain.
