文档 图片 131/1000 实时翻译 划译 The ultra-low noise polarization diversity receiving module is designed for polarization sensitive fiber sensing applications. This polarization diversity receiving module coherently separates the two polarization states of the local oscillator light and the signal light, and uses two high-speed low-noise balanced detectors for separate reception, which can effectively solve the problem of coherent polarization states. This series is an upgrade based on the Yuan PDR series, which significantly reduces background noise and thus achieves a higher signal-to-noise ratio for detection signals.
