  • Disadvantages of excessively high power in optical modules

    Disadvantages of excessively high power in optical modules

    In fiber-optic communication systems, long-distance optical modules, due to their high transmit optical power, are highly susceptible to damage to receiving devices when directly connected to shorter optical fibers. Despite all these constraints, in optical communication, the bit rate still needs to be increased. To meet the growing demand, two main approaches are explored: increasing the carrier frequency and using higher-order modulation techniques. The common challenge for all optical modules is to fit this increased. The most significant advantage of optical chips lies in their high bandwidth and high-speed transmission capacity.
