A DFB laser is a laser diode or optical fiber laser. DFB Laser has a low linewidth grating that extends throughout the cavity rather than simply at the opposite edges. DFB Laser are single-frequency lasers, with short linewidth and effective side modes.
Difference Between FP Laser and DFB Laser.
It is mostly used for high-rate and medium-long-distance transmission. The transmission distance of the FP laser is usually within 20 km. The transmission distance of the DFB laser is usually above 40 km.
