800～2000nm multimode Pump laser protectors central pump
Pump protector is to prevent the generated ASE back reflection light from causing damage to the pump laser. We can provide different power pump protectors in the band of 800 ~ 2000nm.
- High power tolerance
- Low insertion loss
- High stability and reliability
- Fiber lasers and fiber amplifiers
- optical fiber communication system
- Fiber optic sensing
- Scientific experimental research

Note: The temperature measurement environment is 25℃; the above data does not include the head. If the joint is added, the insertion loss will increase by 0.3dB, the return loss will decrease by 5dB, and the extinction ratio of the polarization-preserving product will decrease by 2dB. The default slow-axis alignment key of the optical fiber is key.
