| Zusammenfassung: | An inspection apparatus for an optical transmission device selects an optical path in accordance with the wavelength of an optical signal transmitted from the optical transmission device and displays an indication of the wavelength of the selected optical signal according to an electrical signal. Thus, an optical transmission device used for single-optical-fiber bidirectional transmission easily can be checked as to whether it is provided for a subscriber or for a central station using different wavelengths. |
