HAPM4000 is a Polarization Maintaining Optical Amplifier which working in 1528~1563nm operating wavelength. Adopt Polarization Maintaining Erbium-doped fiber (PM-EDF), output optical power range 13~26dBm, extinction ratio >20dB.
HAPM4000 input and output both adopt single-polarized optical isolator and PM optical component. This equipment is used to ensure the high extinction ratio and the stability of amplified output polarization. Mainly maintained by narrow linewidth, single channel seed laser source‘s power amplification and PM in 1540~1570nm wavelength range.
