Fixed Attenuator

C-LIGHT ‌Fixed Attenuator‌ is a passive device with a fixed attenuation value, using built-in resistors or waveguide structures to irreversibly reduce the intensity of optical or electrical signals. It is commonly employed in fiber-optic communications, RF systems, and testing equipment for signal level matching, system calibration, or protecting sensitive components‌. Key specifications include attenuation value (e.g., 3dB, 10dB), insertion loss, frequency range, and temperature coefficient, offering advantages such as simple structure, high stability, and low cost for applications requiring no dynamic adjustment‌.
