Coherent 100G field trial over installed fiber links: Investigating key network scenarios and applications [Invited].

We report a successful coherent 100G field trial over installed fiber links of a total of 769 km, investigating the performance of coherent technology for key network scenarios and applications including network upgrade, a new dispersion-compensation-module-less network design, polarization mode dispersion tolerance and support for alien wavelengths. In addition, we evaluated the end to end transport performance of 100GE and 10GE client signals. [ABSTRACT FROM PUBLISHER]
