Measurements of a Novel FTTH/PON Monitoring Technique based on Unique Wavelength-Selective Mirror Combinations using Composite Coding Scheme OTDR for

Composite Coding Schemes for OTDR SNR enhancement have been proposed in theory and have not been evaluated yet by experiments to the best of our knowledge. A Composite Coding Scheme was implemented to an OTDR measurement set-up to enhance the SNR of measurements and enable supervision of PONs with higher splitting factors and reach. The Composite Coding Scheme OTDR is combined with a novel monitoring concept for passive optical networks (PON) which is based on unique combinations of concatenated wavelength selective mirrors. A subscriber identification was enabled after 33.5 dB one-way attenuation.
