In this paper, a direct comparison of signal loss on a network arising from both vibration and non – vibration source using the Anritsu Optical Time Domain Reflectometer (OTDR) has been made. The vibration was generated through a flask shaker, generator and heavy duty truck, which aims at ascertaining the effect of vibration on the network and the need to shield the network from vibration as much as possible. The results of this study was able to show that even in the absence of presumed vibration, a network of this kind can still experience signal losses, but greater losses are most likely to be recorded in the presence of a deliberate generation of vibration on the network. Hence; from this study, the OTDR has been used to acquire these signal losses on the optical fibre cable used for the network for the both cases above and at the end, an overall end – to – end loss of 3.90dB for both cases were observed and a reflected loss of -33.31dB and -33.34dB was obtained for both the non – vibration and vibration source respectively.
