PROBLEM TO BE SOLVED: To provide optical communication monitor equipment where a user can determine easily power level of all channels or a desired channel and the cost is reduced. SOLUTION: The optical communication monitor equipment 11 is provided with a display part 14, which displays the measured result of optical power level of each channel. The display part 14 is arranged on an outer surface 16a of an equipment body 16 and is provided with LEDs 30, which display optical power level of each of the channels to all channels. On the outer surface 16a, channel numbers are described at positions, corresponding to the LEDs 30 of each of the channels. By only taking a glance at the on/off states of the LEDs 30 of each of the channels, it can be decided easily whether optical power level of all channels is normal or which channel is abnormal in the optical power level. |
