Polarization Maintaining Erbium-doped Fiber Amplifier

Product Details

 HC-EDFA-PM polarization maintaining erbium-doped fiber amplifier is a single-polarization amplification 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 that the polarization extinction ratio of the whole optical path is better than 20 dB, and the maximum output of 33 dBm can be achieved.

 For different applications, a variety of amplification structures can be provided for selection: 1. Conventional single-stage amplification structure; 2. Single-stage low-noise optimization structure; 3. Double-stage amplification structure; 4. Three-stage amplification and other structures. For different applications, the lowest noise can achieve a noise figure of 3.6 dB, and the high gain can achieve a gain of more than 45 dB. The multistage amplification structure has the effect of improving the OSNR, and can realize lower ASE noise output by being matched with a narrow-band ASE filter at the same time, and can provide amplification of weak linearly polarized optical signals for some special application fields, such as coherent optical communication, laser radar, meteorological wind direction detection and other application fields.
