Using III-V Lab 100G circuit, Alcatel-Lucent demonstrates Tb/s transmission over 3200km


A 1-Tb/s demonstration was shown at OFC/NFOEC conference (19-21 March 2013, Anaheim CA, USA), running during the whole exhibition.
It included a five dual-carrier channels transmission over 3200 km at 5.2-b/s.Hz spectral efficiency, using coherent detection, off-line digital signal processing, and soft-decision forward error correction.

The 1-Tb/s dual-carrier PDM-16QAM (dual-polarization quadrature amplitude modulation) transmission is based on all-electronic 80-GBaudmodulation per subcarrier, achieved thanks to the state-of-the-art multiplexer designed, fabricated and packaged in III-V Lab. The performance of this integrated circuit was the key to setting up this demonstration.

This same circuit was used in the experiment reported as postdeadline paper at OFC 2013 conference: “Single-carrier 400G interface and 10-channel WDM transmission over 4800 km using all-ETDM 107-Gbaud PDM-QPSK”, by Gregory Raybon and colleagues from Alcatel-Lucent Bell Laboratories, USA, and Agnieszka Konczykowska, Filipe Jorge, and Jean-Yves Dupuy, from III-V Lab, a joint laboratory of Alcatel-Lucent Bell Labs, Thales Research & Technology and CEA-Leti.
