We have 7 series of erbium-doped fiber amplifiers: PM-EDFA, BA-EDFA, pre-EDFA, pulse EDFA, high power EDFA, Bidi-EDFA and Raman fiber amplifier.
The STK-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:
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.
