Abstract We compare optical time domain reflectometry OTDR techniques based on conventional single impulse, coding and linear frequency chirps concerning their signal to noise ratio SNR enhancements by measurements in a passive optical network PON with a maximum one-way attenuation of 36.6 dB. A total of six subscribers, each represented by a unique mirror pair with narrow reflection bandwidths, are installed within a distance of 14 m. The spatial resolution of the OTDR set-up is 3.0 m.
