No, the acoustic sensing ability of the FOTAS system does not get affected by environmental conditions. The FOTAS acoustic sensing interrogator and processing unit are kept in a safe system room. On the other hand, the sensing fiber optic cable has a firm coating and it is buried underground so it isn’t affected from the environmental conditions. With this, we have an effective system which is able to work in harsh environments. It can also be used to watch underwater cables because of this ability.
