EXPERIMENTAL INVESTIGATION OF 28-GBD POLARIZATION-SWITCHED QUADRATURE PHASE-SHIFT KEYING SIGNALS
Johannes K. Fischer1, Lutz Molle1, Markus Nölle1, Dirk-Daniel Gross1, Colja Schubert1; 1Photonic Networks and Systems, Fraunhofer Heinrich-Hertz-Institut, Germany.
We experimentally generate 28-GBd polarization-switched quadrature phase-shift keying signals. In transmission experiments over up to 12500 km ultra-large effective-area fiber, we compare their performance to polarization-multiplexed quadrature phase shift keying signals at the same bitrate.

ULTRA-LONG-HAUL TRANSMISSION OF 7×42.9GBIT/S PS-QPSK AND PM-BPSK
Carsten Behrens1, Domanic Lavery1, David Millar1, Sergejs Makovejs1, Benn C. Thomsen1, Robert Killey1, Seb Savory1, Polina Bayvel1; 1Electronic & Electrical Engineering, University College London, United Kingdom.
We report on ultra-long haul transmission of polarization-switched QPSK (PS-QPSK) and polarization-multiplexed BPSK (PM-BPSK) at 42.9Gbit/s per WDM channel. Although achieving similar transmission distances in excess of 13,600km, PS-QPSK offers a significant reduction in receiver complexity due to a lower symbol-rate.

EXPERIMENTAL COMPARISON OF 28GBAUD POLARIZATION SWITCHED- AND POLARIZATION DIVISION MULTIPLEXED- QPSK IN WDM LONG-HAUL TRANSMISSION SYSTEM
Jeremie Renaudier1, Oriol Bertran Pardo1, Haik Mardoyan1, Massimiliano Salsi1, Patrice Tran1, Eric Dutisseuil1, Gabriel Charlet1, Sebastien Bigo1; 1Bell Labs, Alcatel-lucent, France.
We report on experimental long-haul transmission of 28Gaud PS-QPSK signal in a WDM scenario. We compare its performance with that of 28Gbaud PDM-QPSK signal and demonstrate it could be interesting into software-defined optical transceivers.
 
Mo.2.B.4 • 17:30
GLOBAL OPTIMIZATION OF FIBER-OPTIC COMMUNICATION SYSTEMS USING FOUR-DIMENSIONAL MODULATION FORMATS
Leonardo Coelho1, Norbert Hanik1; 1Institute for Communications Engineering, Technische Universität München, Germany.
 Using a global optimization algorithm, we show that significant gain in performance can be obtained by using the Ungerboeck's set-partitioning scheme for DP-QPSK and DP-16QAM in four dimensions.
 
Mo.2.B.5 • 17:45
LINEAR AND NONLINEAR CROSSTALK TOLERANCE OF POLARIZATION-SWITCHED QPSK AND POLARIZATION-MULTIPLEXED QPSK
Martin Sjödin1, Pontus Johannisson1, Peter Andrekson1, Magnus Karlsson1; 1Microtechnology and Nanoscience, Chalmers University of Technology, Sweden.
The OSNR requirements and linear crosstalk tolerance of PS-QPSK and PM-QPSK are investigated, as well as the transmission performance in the presence of 10 Gbit/s neighboring OOK channels.
 
Mo.2.B.6 • 18:00
A COMPARISON BETWEEN SSMF AND LARGE-AEFF PURE-SILICA CORE FIBER FOR ULTRA LONG-HAUL 100G TRANSMISSION
Vincent Sleiffer1,2, Dirk Van den Borne2, Maxim Kuschnerov2, Vladimir Veljanovski2, Masaaki Hirano3, Yoshinori Yamamoto3, Takashi Sasaki3, Sander Jansen2, Huug De Waardt1; 1Electrical Engineering, University of Technology Eindhoven, Netherlands; 2Nokia Siemens Networks, Germany; 3Sumitomo Electric Industries, Japan.
We compare the transmission performance of 112-Gb/s POLMUX-QPSK modulation over large-Aeff Pure-Silica core fiber and SSMF using EDFA-only amplification. The higher nonlinear threshold of the large-Aeff fiber allows for a 40% improvement in transmission distance.

TRANSMISSION OVER 2400 KM USING AN ALL-ETDM 80-GBAUD (160-GB/S) QPSK TRANSMITTER AND COHERENT RECEIVER
Gregory Raybon1, Peter Winzer1, Andrew Adamiecki1, Alan Gnauck1, Agnieszka Konczykowska2, Filipe Jorge2, Jean-Yves Dupuy2, Roger Delbue3, Peter Pupalaikis3, Larry Buhl1, Christopher R. Doerr1, Sethumadhavan Chandrasekhar1, Benyuan Zhu4, David Peckham4; 1Alcatel-Lucent, USA; 2III-V Lab, joint lab between Bell Labs, TRT and CEA/Leti, France; 3LeCroy Corporation, USA; 4OFS Labs, USA.
A single-polarization 160-Gb/s (80-Gbaud) electronically multiplexed (ETDM) single-carrier quadrature phase-shift-keyed (QPSK) signal is transmitted over 2400 km of ultra-large-area fiber. Coherent detection is achieved using two 120-GSamples/s, 45-GHz bandwidth oscilloscope prototypes and off-line digital signal processing.
