product description：
KG-PLBOX series of light pulse modulators are designed for photoelectric detection and the generation of a weak pulse of the optical fiber sensor system. This instrument can produce the narrowest up to 1.5ns light pulse, dynamic extinction ratio up to 30dB, pulse Width, and frequency are adjustable. The internal integrated bias control circuit, ensuring that the output light pulse signal does not produce drifts by the external environment such as temperature, facilitates the user and dramatically improves the reliability of the modulator.
