Electro-Absorption Modulated Laser (EML) 12GHz

The EMLT Series Electro-Absorption Modulated Laser Transmitter is a semiconductor laser that integrates a distributed feedback (DFB) laser and an electro-absorption modulator (EAM) within a single package. This design eliminates the need for external modulators, reducing system complexity, power consumption, and size while improving thermal management. Capable of modulation speeds up to 20 GHz for both analog and digital responses, the EMLT delivers high-speed modulation with precise optical output control. The integrated EAM minimizes wavelength shifts during modulation, ensuring stable signal transmission over long distances, making the EMLT ideal for high-speed optical communication systems. Its compact and efficient design is well-suited for modern applications requiring reliable, high-performance data transmission.
