Based on the laser amplification principle of the
optical signal in the erbium-doped fiber, C-band high power
polarization preserving EDFA realizes the high power polarization
preserving output of 1540~1565nm laser by adopting the unique
multi-stage optical amplification design and reliable high power
laser cooling process. It has the advantages of high power, high
extinction ratio and low noise, and can be used in optical fiber
communication, laser radar, etc.
