  • Optical module modulates optical signal

    Optical module modulates optical signal

    The optical module serves as a crucial component in optical fiber communication systems, operating at the physical layer, which is the lowest layer in the OSI model. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. 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. Similarly, blankets used to cover a signal fire periodically produced puffs of smoke that could be seen for miles in the clear desert air, producing, in effect, a modulated signal.
