Inventor: AOYAMA SHIGEYUKI
IPC: H04B10/07
Filed: 1992-11-05
Abstract: PURPOSE:To prevent the degradation of a C/N and distortion characteristic due to the decrease of the number of channels for light transmission. CONSTITUTION:A level adjustment is executed by a detector circuit 15, a differential amplifier 14, and a PIN variable attenuator 13, so that the total sum of the signal level in the entire transmission band of a signal outputted by an amplifier 12 can be equal to a value indicated by a prescribed voltage Vr1. Therefore, the level of the signal inputted to an amplifier 11 is decreased according as the number of the channels is decreased, and the attenuating amount of the PIN diode variable attenuator 13 is decreased so that the total sum of the signal level outputted by the amplifier 12 can be equal to the value indicated by the reference voltage Vr1. On the other hand, at a reception side, the level at the time of demodulation is adjusted by a band pass filter 24, a detector circuit 26, a differential amplifier 27, and a PIN variable attenuator 22, so that the level of the pilot signal of a prescribed frequency can be turned to a prescribed value.
