Product Description

Variable Connector Attenuators (VCA) work on the air gap principle. Attenuation variation is achieved by controlling longitudinal offset. These attenuators use standard fibres that are currently deployed in optical systems. No special fibres, filters or optical elements are used.
VCA attenuators are compatible with standard fibre optic connectors and adapters allowing you to quickly and easily introduce a variable insertion loss into the optical network.
