OPTISCHE KOMMUNIKATIONSEINHEIT

摘要

Information processors are interconnected via an optical communication apparatus and an optical communication medium to perform data communication. Each information processor has a standard interface which operates based on electric signals, and input/output control is executed in accordance with the standard interface specifications. The optical communication apparatus is provided with an input electric signal from the information processor, converts the electric signal into a corresponding optical signal upon performing pulse-width modulation in such a manner that the pulse width differs at the leading and trailing edges of the electric signal, and outputs the optical signal to the optical communication medium. Conversely, the apparatus is provided with a pulse-width modulated input optical signal from the optical communication medium, discriminates the leading and trailing edges of an electric signal from the pulse width, demodulates the optical signal and converts it into a corresponding electric signal outputted to the information processor. The optical communication apparatus produces all of the required driving power from output electric signal lines from the information processor.
