Vapor phase corrosion inhibitor (VpCI) technology is used to protect metallic parts used to build electronic equipment. The use of fiber optics is ever increasing in the electronic industry. Fiber optics found in cable connectors could, at times, be exposed to VpCI compounds. The emergence of VpCI technology for the protection of equipment used in the fiber optic industry required a further study of the impact that thin VpCI layers have on signal attenuation.
