Abstract
An asset such as a data transmission system, a perimeter security system, an oil well or a pipe line is monitored for events which are potentially damaging or threatening to the asset by installing an optical fiber continuously through the asset. The asset has many different zones of different physical condition, environment and/or of different risk factors which are expected therefore to generate different responses to events. The fiber is monitored using a distributed acoustic sensing (DAS) interrogator by effecting an analysis to determine the presence of an event in one or more of the zones The analysis includes applying different gauge length parameters to received data signals from the different zones at the same time.
