The FF-3303A/B handheld optical variable attenuator can conveniently and quickly complete the continuous variable attenuation of optical signals from 0dB to 30dB/0dB to 60dB, with a high attenuation accuracy of 0.1dB, providing 5 commonly used wavelengths of light attenuation function, backlight adjustment and display function, precise attenuation accuracy, and user self calibration function. It has a universal interface design, and the attenuation value is displayed on the LCD screen. Mainly used for the construction, upgrading, and daily maintenance of fiber optic communication systems and networks, widely used in fields such as fiber optic cable construction and maintenance, fiber optic communication, fiber optic sensing, and optical CATV.
