Adjustable Attenuator

C-LIGHT ‌Adjustable Attenuator‌ is a device capable of dynamically adjusting signal attenuation levels through mechanical or electronic means, primarily used to precisely control the transmission intensity of optical or electrical signals in fiber-optic communications, RF systems, and microwave circuits‌. Its core structure typically includes waveguide components, movable absorbing materials, and adjustment mechanisms, enabling continuous or stepped attenuation control by altering the relative position of the absorber to the waveguide or adjusting the channel cross-sectional area‌. Such attenuators feature low standing wave ratios, wide dynamic ranges, and high frequency stability, making them suitable for laboratory testing, network optimization, and equipment calibration‌.
