This video shows the complete fiber optic attenuator manufacturing process — from attenuation value design and fiber alignment to final optical testing. Fiber optic attenuators are widely used to control signal power in data centers, telecom networks, and FTTx systems, preventing receiver overload. Thorlabs has a wide variety of single mode (SM), polarization-maintaining (PM), or multimode (MM) fixed and variable optical attenuators (VOAs). We offer SM and PM electronic VOAs that provide control of the output power with FC/PC or FC/APC connectors. VIAVI offers the industry's most complete range of optical attenuators for installation and maintenance of singlemode and multimode. Optical attenuators are passive components used to reduce optical signal power to a controlled level within a fiber optic system. They do not modify the signal content, wavelength, or transmission path.
