980/1060nm WDM 1X2 PM Fiber Wavelength Division Multiplexer FC/APC Slow Axis is Aligned with K Key
The polarization-maintaining wavelength division multiplexer is a device that couples optical signals of different wavelengths into a fiber. The most common application is to couple the pump light signal and the polarization signal light into a fiber. Therefore, in the polarization-maintaining fiber Amplifiers and polarization-maintaining fiber lasers are essential components.
