Product Description
800～2000nm multimode Pump protectors
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.
Feature:
- High power tolerance
- Low insertion loss
- High stability and reliability
Application:
- Fiber lasers and fiber amplifiers
- optical fiber communication system
- Fiber optic sensing
- Scientific experimental research
Specification:

| Central pump laser wavelength (nm) | 793/808 | 915/974/976 | |
| Working wavelength bandwidth (nm) | ±15 | ||
| Signal wavelength range (nm) | 1020～1120 | 1020～1120 | 1530～1570 |
| Insert loss Max. (dB) @ Through wavelength | 0.6 | ||

| Tensile power-CW (W) | 0.5, 1, 5, 10 or other | ||
| Type of optical fiber | MM fiber | ||
| Fiber length (m) | 1 or other | ||
| Type of connector | FC/APC or other | ||
| maximum pull (N) | 5 | ||
| Encapsulation size (mm) | φ 5.5 x L35, or 60 x 12 x 8 | ||
| working temperature (℃) | -5～+60 | ||
| storage temperature (℃) | -40～+85 | ||
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.
