  • In fiber optic communication DML is

    In fiber optic communication DML is

    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. At its core, an optical module performs (opto-electronic conversion), transforming electrical signals into optical signals for transmission over fiber, and vice versa. What are EML and DML Lasers?DML stands for Directly Modulated Laser. Its basic principle is to directly control the current passing through the laser diode (LD) to generate optical signals of different intensities: • When the modulation signal is at a high level: Modulation current flows through the LD, and the laser emits. DML is the abbreviation of Directly Modulated Laser, that is, directly modulated laser.
