ABSTRACT:
A frequency-multiplex optical transmission apparatus for carrying out frequency-multiplex optical transmission by supplying an analog-frequency-multiplexed RF input signal to a laser diode. In the apparatus, part of the RF input signal taken out by a splitter is detected by a power detector. In response to an output signal of the power detector, an indicator driver causes an indicator to indicate a modulation signal level for the laser diode. The level of the RF input signal is adjustable by an attenuator while observing the indication state of the indicator.
