Th4.1 - Post-Deadline Session 1
Chair: René Jean Essiambre, Bell Laboratories, Lucent Technologies, France

Post deadline sessions are all a standard 15 (12 +3) minutes.

Th4.1.1 16.00 – 16.15
107-Gb/s Optical ETDM Transmitter for 100G Ethernet Transport
P J Winzer, G Raybon, M Duelk, Bell Laboratories, Lucent Technologies, United States

Using optical duobinary modulation, we demonstrate the first electrical time-division multiplexed (ETDM) optical transmitter at 107 Gb/s, suitable for serial transport of 100G Ethernet.

Th4.1.2 16.15 – 16.30
Single Channel 1.28 Tbit/s and 2.56 Tbit/s DQPSK Transmission
H G Weber, S Ferber, M Kroh, C Schmidt-Langhorst, R Ludwig, V Marembert, C Boerner, C Schubert, Fraunhofer Institute for Telecommunications, Germany, F Futami, S Watanabe, Fujitsu Laboratories Ltd, Japan

By combining the techniques of optical TDM with polarisation multiplexing and DQPSK modulation, we performed 240 km transmission of 1.28Tbit/s and 160 km transmission of 2.56 Tbit/s in a single wavelength channel.

Th4.1.3 16.30 – 16.45
151x43Gb/s Transmission over 4,080km based on Return-to-Zero-Differential Quadrature Phase-Shift Keying
G Charlet, P Tran, H Mardoyan, M Lefrancois, T Fauconnier, S Bigo,
Alcatel Research & Innovation, France, F Jorge, Alcatel Thales III V Lab, France

We demonstrate a record distance with Nx43Gb/s RZ-DQPSK modulated channels. More than 1.5dB margin is measured for all 151 WDM, 50GHz-spaced channels at the end of the system, based on 70nm-wide Raman repeaters.

Th4.1.4 16.45 – 17.00
85.4 Gbit/s ETDM Transmission over 401 km SSMF Applying UFEC
K Schuh, B Junginger, H Rempp, P Klose, D Rösener, E Lach, Alcatel Research & Innovation, Germany

We report on an 85.4 Gbit/s ETDM transmission system with implemented Ultra-FEC. In a transmission experiment over 401 km standard singlemode fibre error free operation is achieved after Ultra-FEC correction.

Th4.1.5 17.00 – 17.15
26x42.8-Gbit/s DQPSK Transmission with 0.8-bit/s/Hz Spectral Efficiency over 4,500-km SSMF using Optical Phase Conjugation
S L Jansen, D van den Borne, G D Khoe, H de Waardt, Eindhoven University of Technology, The Netherlands, A Schöpflin, E Gottwald, P M Krummrich, Siemens AG, Germany

Employing optical phase conjugation with a polarisation-diversity periodically-poled lithium-niobate subsystem, we experimentally demonstrate 42.8-Gbit/s RZ-DQPSK DWDM transmission with 0.8-bit/s/Hz spectral efficiency over 4,500 km of SSMF without inline dispersion compensation.

Th4.1.6 17.15 – 17.30
Penalty-free Transmission of Multilevel 240 Gbit/s RZ-DQPSK-ASK using only 40 Gbit/s Equipment
T Tokle, Y Geng, J B Jensen, P Jeppesen, Research Center COM, Technical University of Denmark, Denmark, M Serbay, W Rosenkranz, University of Kiel, Germany

Combining four-level phase modulation with binary amplitude modulation and polarisation multiplexing at 40 Gbaud, we present the first experimental implementation of 240 Gbit/s RZ-DQPSK-ASK. We demonstrate transmission over a 50 km fibre span without sensitivity degradation.
