The figures are as follows:

Fig. 2     OTDR: The OTDR trace for 152km of sensing fibre. This OTDR trace clearly indicates the location of the EDFA and micro-machined enhanced fibre.

Fig. 3(a)  Waterfall Plot: 3D representation of vibration along the sensing fibre known as waterfall plot.
	   All the vibration at the far-end of the sensing fibre enhanced fibre is used to detect vibrations.

Fig. 3(b)  Time Domain 2D: A 2D cross section of the waterfall plot at a fixed point on the fibre where the PZT is located.

Fig. 4(a)  Linearity: A linear relationship between input voltage to the PZT and DAS reading.

Fig. 4(b)  PSD: The power spectral density of the DAS system.
