PM-EDFA

Product introductionThe 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 outp...
