Provided is an optical transmission module (10) that includes: a semiconductor light emitting element (18) for emitting laser light; a first driving unit (40) for providing a first driving current to the semiconductor light emitting element; a switching unit (44) connected between the semiconductor light emitting element (18) and the first driving unit (40); and a package for accommodating the semiconductor light emitting element (18), the first driving unit (40), and the switching unit (44). The switching unit includes a first input (44a) for receiving a first driving current outputted from at least from the first driving unit, a second input (44b) for receiving a second driving current for testing the semiconductor light emitting element, and an output (44d) connected to the semiconductor light emitting element (18). The switching unit (44) connects the first input (44a) or the second input (44b) to the output (44d). |
