An optical module includes a casing, a first light output unit that is fixed to the casing and generates a first light signal, a second light output unit that is fixed to the casing while an angle thereof is set to be different from that of the first light output unit and generates a second light signal having a wavelength different from that of the first light signal, a first branching filter that refracts at least any one of the first light signal and the second light signal so that optical axes of the first light signal and the second light signal are partially overlapped, and one isolator that is located at a portion where optical axes of the first light signal and the second light signal are overlapped and performs isolation on the first light signal and the second light signal. |
