Field trial at 40 Gbit/s over 28.6 and 86 kmof standard singlemode fibre using quaternary dispersion supported transmission

Abstract

40 Gbit/s transmission using a single optical carrier and electrical time division multiplexing is demonstrated for the first time reusing standard singlemode fibres from the existing fibre infrastructure of Portugal Telecom. Bit error measurements as well as video transmission via STM1 interfaces demonstrate the robustness of dispersion supported transmission under real operating conditions.
