DML (Directly Modulated Laser) is a type of laser that modulates the optical signal by directly adjusting the driving current of the laser. Unlike EML, DML adopts a simpler structure by integrating the modulation function within the laser, resulting in lower cost and power. Explore the differences between EML (Electro-absorption Modulated Laser) and DML (Directly Modulated Laser) technologies in optical transceivers. Learn about their working principles, advantages, disadvantages, and key considerations for choosing the right laser for your optical communication. Optical communication plays a crucial role in modern information transmission, enabling high-speed data transfer over long distances. Higher bandwidth (extremely high data transfer rate). • DML Modulation DML stands for Directly Modulated Laser. Or It is also suited for analog fiber transmission.
