Good-quality long-distance optical transmission over fiber needs lasers which emit at a single wavelength. This is almost universally realized by putting a wavelength-dependent reflector into the
Distributed feedback lasers offer improved wavelength stability as compared to cleaved-end-face lasers, because the grating tends to lock the laser to a given wavelength.
In a DFB laser, the grating and the reflection is generally continuous along the cavity, instead of just being at the two ends. This changes the modal behavior considerably and makes the laser more stable.
A distributed feedback laser (DFB laser) is a type of laser that emits light of a single frequency. This is achieved by incorporating a distributed feedback grating (DFB
