Abstract
An optical module includes: a laser device; a wavelength detector; a modulator; a modulator driver; a coherent mixer; a photoelectric element; a transimpedance amplifier; and a casing. Further, the laser device is arranged such that the laser device outputs a laser light beam in a direction opposite to a side on which the optical output unit is arranged in the casing.
