We report the first successful real-time superchannel trials up to 5.6Tb/s over 359km and 2Tb/s over a live 727km link using 64GBaud flexible-rate transponders, demonstrating long term error-free performance and fast capacity turn-up of ∼2Tb/min.
Directly modulated lasers provide simple, and cost efficient, optical transmitters for use in optical networks. However, chirp limits the bit rate distance product achievable in such systems, with transmission distances limited to around 10 km when operating at 10 Gbit/s in the 1550 nm window [1, 2], and thereby limiting their suitability as optical transmitters in next generation access networks...
