Optical modules convert electrical signals into optical signals and can encode information using different modulation modes. The modulation can be performed directly on the laser diode (direct modulation) or via a separate optical modulator (external modulation) integrated into the module . Direct modulation is simpler but can introduce phase noise and wavelength drift at high speeds, while external modulation provides higher signal quality and longer transmission distances .
Optical modules indeed have multiple modulation modes, which can be selected based on application requirements such as data rate, transmission distance, and signal fidelity. The choice between direct and external modulation, along with the specific modulation scheme, determines the performance and efficiency of the optical communication system .

An optical modulator is a device which is used to modulate a beam of light. The beam may be carried over free space, or propagated through an optical waveguide (optical fibre). Depending on the parameter of a light beam which is manipulated, modulators may be categorized into amplitude modulators, phase modulators, polarization modulators, etc. The easiest way to obtain modulation of intensity of a light beam is to modulate the current driving the light source, e.g. a laser diode. This sort of modulation is c
