Gooch & Housego (G&H) utilizes a proprietary manufacturing technology that provides accurate attenuation with low wavelength, temperature and polarization dependence. Here are the top-ranked optical attenuator companies as of May, 2026: 1. What Is an Optical Attenuator? What Is an Optical Attenuator? An optical attenuator is a device that attenuates optical fiber signals to adjust them to an appropriate. Attenuators from VIAVI offer a complete range of power-balancing options, from fixed to variable optical attenuators in field, lab, and manufacturing environments. VIAVI offers the industry's most complete range of optical attenuators for installation and maintenance of singlemode and multimode. Optical attenuators are devices designed to reduce the optical power of a light beam or signal by a specific ratio (attenuation factor), typically expressed in decibels (dB). All of our attenuators operate over the two standard wavelength bands, the C-Band and the L-Band.
