Therefore, optical performance is never degraded because of falling, the backlash, etc. The rolling friction of the balls 2 whose resistance is low is used to reduce shift driving force by electromagnetic drive. Further, the turning around the optical axis of the movable frame 4 is prevented by a pair of tension springs 6 facing each other and the pressing force of the movable frame 4 on the balls 2 is generated to prevent the backlash in the optical axial direction at the shifting time.

Abstract: PURPOSE:To prevent the generation of an error signal by increasing an idle level of an input signal to a limiter amplifier more than its fixed reference voltage. CONSTITUTION:A burst optical signal received at the reception side is converted into an electric signal, and the signal is given to an AC coupling single end input limiter amplifier 3, where the signal is identified, and the input signal level of the limiter amplifier 3 in the transmission idle state is outputted so as to increase the level of the input signal more than the fixed reference voltage of the limiter amplifier 3 through the increased pulse occupancy rate of the burst optical signal. That is, since the input to the limiter amplifier 3 is at the idle level and larger than the fixed reference voltage, even if the signal is amplified in the amplifier and given to a comparator 5 through a capacitor, no error signal takes place because no overshoot is occurred.
