Description/Abstract

A technique for increasing the dynamic of a 1.65µm OTDR system has been demonstrated. This is achieved by Raman amplification of the 1.65µm pulse within the sensing fibre using a co-propagating 1.53µm pulse generated from a Q-switched erbium doped fibre laser. An increase in dynamic range of 17.5dB has been demonstrated, providing an OTDR trace over 100km on the test fibre.
