1425nm 1455nm 350mW 500mW Pump نظام الليزر الليفي for Fiber مضخم رامان -- نوع الوحدة
مضخم الألياف رامان uses the Raman effect in quartz fiber to provide gain to optical signals, and achieves high gain and low noise amplification of optical signals in the C or L band, which can effectively compensate for the attenuation of optical signals in long-distance optical fiber transmission. It can be used in long-distance optical transmission systems, distributed optical fiber sensing, and intensive wavelength division multiplexing optical transmission systems.
