Abstract

PURPOSE:To facilitate an eacy display for incoming in the optical telephone system, by transmitting the incoming optical signal from the switchboard and then driving the sound generating source via the incoming optical signal for the telephone. CONSTITUTION:In case the telephone 3 has an incoming, the light emitting element 11b of the switchboard 1 is driven. And then the sound generating source 33 is driven by the optical signal via the coupler 12, the optical fiber 2, the branching filter 31 and the optical switch part 32 each. With hook-off of the handset of the telephone circuit 34, the part 32 switches off the incoming optical signal. Thus the driving of the sound generating source is discontinued.
