Abstract

The performance of Khazani Syed (KS) code based fiber vibration measurement for distributed sensing has been investigated. The setup was aimed at implementing quasi distributed vibration sensing with less complexity and optimum performance against Multiple Access Interference. The three sensor points system were compared with existing Optical Orthogonal Code (OOC) and Modified Congruence Code (MQC) in terms of level of power received, supported fiber length and complexity in implementation. Slightly better received power and longer fiber length were demonstrated by the system employing MQC code but a wide gap to OOC code. However, since KS code is implemented with less number of components which tends to reduce the cost and complexity of the system which becomes obvious as the sensor points grow, KS code is recommended for the quasi distributed vibration sensing.
