Title:
OPTICAL FIBER DATA COUPLER
Document Type and Number:
Japanese Patent JPH0292032
Kind Code:
A
Abstract:
PURPOSE: To facilitate precise alignment, to prevent a fault in the case of assembling and to extend a service life by providing an optical fiber data link input output module, a coupler drive module, an inductive coupler unit and a coupler output module so as to configure the coupler. CONSTITUTION: The signal amplified by an amplifier 20 is fed to an inlet of an inductive coupler unit 3. Then a current is induced in an outlet part 10 by a concentric ferrite face 8 in the inlet part 5 and a corresponding face in the outlet part 10. The outlet part 10 is connected to an amplifier 21. The amplified signal is fed to a decoder 22 incorporating a modem chip that realizes an FSK or DPSK function and fed to an LED 23 therefrom. Power supplied to a data coupler 13 is extracted from taps of power cables 26, 27 by means of inductive couplers 28, 29.
