Abstract
A crosstalk measuring method for an optical device includes optically connecting one end of a first optical waveguide to one end of a second optical waveguide via a first connection optical waveguide, inputting pulsed incident light emitted from an OTDR into the other end of the first optical waveguide, outputting, from the other end of the first optical waveguide, first output light including pulsed light in which first crosstalk light is multiplexed with second crosstalk light, measuring power of the first output light, and calculating a magnitude of crosstalk between the first optical waveguide and the second optical waveguide based on the measured power of the first output light.
