ABSTRACT:
An optical fiber measuring apparatus comprises a first laser diode and a second laser diode for producing light outputs of different wavelengths, respectively, a polarized beam splitter to which the light output of the first or second diodes is inputted, an A/O modulator through which the light output having passed through the polarized beam splitter is supplied to an optical fiber, and a first change-over switch for changing over power supplies for the first and second laser diodes, and first and second driving sources for driving the A/O modulator. The outputs of the drive sources are selectively changed over by a second change-over switch. The first and second change-over switches are interlocked in such a manner in which the output of the first driving source is selected when said first power supply is turned on while the output of the second driving source is selected when the output of the second power supply is turned on. The output frequencies of the first and second driving sources are so selected that the light output from the A/O modulator exhibits same first order diffraction angle for the output wavelengths of the first and second laser diodes.
