Product introduction

The KY-EDFA-PM series PM-EDFA is a single-polarization-amplified erbium-doped fiber amplifier. The main optical path of the amplifier is a fully polarization-maintaining optical path (slow-axis operation).High-quality polarization-maintaining devices are used to ensure the polarization extinction ratio of the overall optical path is better than 20dB and output up to 33dBm can be achieved.

For different applications, a variety of amplification structures can be selected: 1, conventional single-stage amplification structure; 2, single-stage low-noise optimization structure; 3, dual-stage amplification structure; 4, dual-stage structure, three-stage amplification, etc. . For different applications, the lowest noise can achieve a noise figure of 3.6dB, and the high gain can achieve a gain of more than 45dB. The multi-stage amplification structure has the effect of improving the OSNR. At the same time, the narrow-band ASE filter can be used to achieve lower ASE noise output, which can provide amplification of weak linearly polarized light signals for special applications, such as coherent optical communication, laser radar,meteorological detection and other fields.
