The meaning of FP Laser A Fabry-Perot laser (FP laser) is a semiconductor light-emitting device that uses an FP cavity as a resonant cavity to create multi-longitudinal mode coherent light. The major applications of FP lasers are low-rate and short-distance transmission. For instance, the speed is typically 1.25G and the transmission distance is typically 20 km. Two wavelengths, 1310nm...
