Find top beam attenuators with variable optical density, high power handling, and adjustable attenuation. Compare verified suppliers, MOQs, and pricing. We make best-in-class optic/electro-optic products based on over 25 years of intensive R&D and rigorous engineering. We strive to provide premium product solutions with unmatched value. Our product offerings are vertical, from components, modules, and turn-key systems for sensing, security, data. Our wide selection of attenuators provide design engineers the flexibility to select products that best suit their system requirements―from GaAs digital attenuators to PIN diode voltage variable attenuators, and silicon fixed attenuator pads for infrastructure, test and measurement, and other high. Optical Attenuation Evolution: Variable Optical Attenuators (VOAs), especially MEMS-based models, offer precise, remote-controlled signal management. Core technologies originated by founder Bruno Weinschel are leveraged using modern design, production, delivery, and service. For custom test system requests, we will respond with a ROM (rough order of magnitude) quote in 1-2 days JFW is committed to anticipating and exceeding. JFW designs and manufactures attenuators, terminations, RF switches, power dividers and remotely controlled test systems with a ISO 9001:2015. ©2025 Newport Corporation.
