1550nm Ultra narrow linewidth DFB laser source
Ultra-narrow linewidth DFB laser source is used in distributed optical fiber sensing systems, passive device testing, fiber optic communications and other fields. A distributed feedback laser diode is used inside the module to output an ultra-narrow optical signal with a wide linewidth, and a built-in optical isolator prevents the return light from damaging the laser diode.
