Abstract

The advantages of fiber optic data communications are well publicized. The system designer trying to solve a particular application problem is faced with many issues involving many technologies if they are to take advantage of fiber optic communication. The information to be transmitted is usually located in a memory or on a processor bus in the form of digital words (bytes) most often as 5 volt CMOS or TTL logic levels. To accomplish the transmission of this information from one system to another over optical fiber the following must be implemented. The data must be converted from parallel to bit serial format. More than likely it will be encoded to guarantee an edge density in the transmission media. It must also include some level of protocol for signaling purposes. These functions are most often implemented in silicon or GaAs integrated circuits. The data must now be amplified and shaped to drive a light source of a specific wave length. This is most often a III V compound semiconductor diode. The source must be critically aligned and mechanically secured with an optical fiber. In most cases an optical connector is involved. At the receiving end the same technologies and processes are used in the reverse direction. The fiber is aligned to a III V diode detector. The signal is amplified and timing is regenerated from the edges. The data is
