Paper Abstract

The optical time domain reflectometer is a powerful diagnostic tool for use on optical networks. However, high spatial resolution can only be obtained at the expense of dynamic range, limiting its effectiveness when applied to high-loss fibre routes. High-gain, wide-bandwidth erbium-doped fibre amplifiers can be used to increase the peak pulse power of narrow OTDR pulses at 1550nm to 2W. An increase of 8dB in dynamic range can be realised whilst maintaining spatial resolution.
