Title:
OPTICAL DATA LINK
Document Type and Number:
Japanese Patent JPH03288106
Kind Code:
A
Abstract:
PURPOSE:To obtain this optical data link wherein an electronic circuit is to affected by the noise of a noisy line even when the noisy line is connected to a case terminal by connecting an island part to an earth terminal and connecting it to an optical connector case through a capacitor. CONSTITUTION:The island part 31 is connected to the earth terminal and then connected to the optical connector case 1 through the capacitor C. Therefore, even if the case terminal is connected to the noisy line, the noise never affects the internal electronic circuit. Further, the capacitor C forms a filter with an inductance parasitic to the connection line between the case terminal and optical connector case 1, so the potential of the optical connector case 1 is never fluctuated by the noise applied to the case terminal. Consequently, the optical data link which is hardly affected by the noise irrelevantly to connections with the case is obtained.
