A non-toxic, economical, and safe bittering agent incorporated directly into AFL's Rodent Deterrent Fiber Optic Cable Jackets reduces damage due to rodent gnawing, while still offering the ruggedness expected from AFL's tactical and OSP fiber optic cables. Ideal for environments where exposed or broken fiber links from rodents results in increased maintenance costs, reduced productivity and possibly lost revenue.  Applications include broadcast, electric utility, industrial environments, oil and gas, and transportation.
