摘要
An optical signal judging system for judging an optical signal outputted from an optical switch the selectively outputs any one of input optical signals, comprises: a converting unit converting at least two optical signals branching off from an optical signal source into optical signals having wavelength bands differing from each other, and thus outputting the optical signals to said optical switch, wherein said optical switch outputs any one of at least the two optical signals so converted as to have the wavelength bands differing from each other, which have been inputted from said converting unit.
