1064nm Ytterbium-doped fiber amplifier YDFA generates gain by pumping ytterbium-doped fiber with semiconductor laser, which is used for laser signal in the 1030nm~1100nm band, Hi1060 single-mode fiber or PM980 polarization-maintaining fiber output, the output power is continuously adjustable, with high gain and With the advantage of low noise, the desktop YDFA is convenient for experimental operation, and the user can adjust the pump current and output power through the buttons on the front panel. A smaller modular YDFA can also be provided, which is convenient for user system integration.
Manual Fiber Polarization Controllers is made by the principle of birefringence generated by optical fiber under the action of external force. The three rings are equivalent to λ/4, λ/2 and λ/4 wave plates respectively. The light wave passes through the λ/4 wave plate and is converted into linearly polarized light, and then the polarization direction is adjusted by the λ/2 wave plate. The polarization state of the linearly polarized light is changed to an arbitrary polarization state via a λ/4 wave plate. The delay effect caused by the birefringence effect is mainly determined by the cladding radius of the fiber, the radius of the fiber surround and the wavelength of the light wave.
The 1450/1550/1660nm 1x3 Raman Filter WDM for DTS Systems Module is manufactured by using thin-film filter technology, it used to separate and combine different signal wavelengths at 1450nm, 1550nm, and 1660nm (or 1650nm).
