AFOP's Variable Optical Attenuators (VOAs) control the optical power in a fiber. They are often combined with an active system component to maintain a desired optical power on a network even if the input signal is changing power. Our VOAs are specifically designed for use with individual channel source elements such as add/drop transmitters in DWDM networks. The cost and performance characteristics of our automatic variable optical attenuators are specifically targeted to allow for the use of these devices in volume as principal DWDM channel stabilization components.

Our optical Fixed Attenuators diminish the optical power at a discrete level within a given optical path without interference or reduction in optical signal quality. Typically this function is embedded in an optical connector or adapter element to simplify optical network installation. We utilize attenuated fiber that reduces power while preserving performance characteristics, including optical signal quality and reliability.
