The objective of this research is to establish a fiber optic communication network and demonstrate the conversion of electrical energy to light (optical) energy. The authors have the further objective of teaching students the characteristics of a real fiber optic system. In the initial design, the authors decided to use commonly available and widely used hardware and software, to construct a fiber optic link step by step, to observe and troubleshoot each step and to catalogue problems and outcomes in order to share this research with students in the college's electronics and industrial engineering technology programs.

The components include a transmitter, a receiver, two converters, and transmission media. The system provides Full-duplex transmission: a data signal can be transmitted in both directions simultaneously. In order to transmit a real message, we decided to use two computers as a basis for a peer-to-peer computer network.

In a conventional communication system, a signal travels over a pair of copper wires toward a receiver. Electrical signals originate in a generator. These data signals are encoded/modulated, and then enter a transmitter. The transmitter transmits the signal over a transmission link. At the receiver side, the signals must be decoded/demodulated to extract the original digital data.

Our system differed from a conventional network because we selected optical fiber as the main transmission medium. The electrical data signal is converted to an optical signal at the transmitter, and then the optical signal is converted to an electrical data signal at the receiver.

Our research consisted of three elements: computers, fiber link, and converters.

We selected two Gateway 2000 computers to transmit and receive messages. Each computer had a central processor microchip (Intel 80486 microprocessor), which has a 66 MHz computer clock speed.

We decided to use Microsoft Windows NT 4.0 Workstation as an operating system, because of its versatility and wide use in industry.
