Abstract :
This paper presents the results of three practical experiments proving the viability of 40 Gbit/s phase-shaped binary transmission (PSBT) channel upgrade to existing 10G systems supporting 50 GHz channel spacing: (a) lab experiments with a fully loaded 1000 km 80-channel 10 Gbit/s system upgraded with two 40 Gbit/s PSBT channels, (b) an 850 km field trial of 40 Gbit/s PSBT channel upgrade to an installed 10 Gbit/s system and installed fiber, (c) an extension of the 850 km field trial to 1700 km via optical loop back. The 10 Gbit/s system was left as originally provisioned and all link control loops were active during the trials. Error free performance after FEC was achieved for all three experimental configurations, proving flexible and seamless 40 Gbit/s PSBT channel upgrade to existing 10 Gbit/s systems is possible and practical.
