The first wavelength is 1940.438 nm, with an optical signal-to-noise ratio (OSNR) of approximately 58.66 dB. The second wavelength is 1940.960 nm, and its OSNR is as high as 71.4 dB. These two wavelengths exhibit two key features: on one hand, through the polarization controller (PC), we can achieve stable and precise wavelength switching control; on the other hand, the high OSNR values indicate excellent spectral purity and signal quality, laying a solid foundation for practical applications. | |
