Trans-oceanic class ultra-Long-Haul Transmission using multi-core fiber.
Optics Express, 2014Co-Authors: Itsuro Morita, Koji Igarashi, Hidenori Takahashi, Takehiro Tsuritani, Masatoshi SuzukiAbstract:Space-division multiplexing with uncoupled multi-core fiber is a promising technology to drastically increase a fiber capacity in optical communication systems. Trans-oceanic class ultra-Long-Haul Transmission was successfully achieved by using 7-core MCF with suppressed inter-core crosstalk. By using a combination of MCF and spectral efficient modulation format, the fiber capacity could be increased from 28.8 Tbit/s to 140 Tbit/s and a capacity-distance product exceeding 1 Exabit/s·km was obtained in 7 cores x 201 λ x 100 Gbit/s Transmission over 7326 km. These results indicate that the MCF Transmission will be one of promising candidates for future ultra-high capacity optical communication systems.

Dispersion-managed high-capacity ultra-Long-Haul Transmission
Journal of Lightwave Technology, 2003Co-Authors: Masatoshi Suzuki, Noboru EdagawaAbstract:The recent progress of dispersion-managed Transmission technologies for ultra-Long-Haul wavelength-division-multiplexing (WDM) systems is reviewed. First, we discuss the dispersion-management technologies for 10 Gb/s-based WDM systems. Next, dispersion-managed technologies for higher bit rate applications are reviewed, including dispersion-managed soliton Transmission. Finally,we compare the effectiveness of different modulation formats for achieving ultradense WDM Transmission for future applications.

Wavelength division multiplexing in Long-Haul Transmission systems
Journal of Lightwave Technology, 1996Co-Authors: Neal S Bergano, C.r. DavidsonAbstract:Wavelength division multiplexing shows great promise for the next generation of Long-Haul undersea cable Transmission systems. WDM techniques will allow for greater Transmission capacity and network flexibility compared to the present single-channel optical amplifier systems. The Transmission of many WDM channels over transoceanic distances can be limited by a variety of phenomena, including the finite bandwidth of the erbium-doped fiber amplifier repeaters, the nonlinear interactions between channels, and the noise accumulation along the chain of amplifiers. Significant progress has been made over the past few years in understanding the nature of these impairments for long-distance Transmission. This paper describes techniques used to transmit many WDM channels over transoceanic distances using the nonreturn-to-zero format and other nonsoliton methods. Data is presented for several WDM experiments including the Transmission of 100 Gb/s (20 channels of 5 Gb/s) over 9100 km

Ultra-Long-Haul Transmission of 7x42.9Gbit/s PS-QPSK and PM-BPSK
2020Co-Authors: Carsten Behrens, Robert I. Killey, Benn Charles Thomsen, Sergejs Makovejs, David S. Millar, Seb J. Savory, Domanic Lavery, Polina BayvelAbstract: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. © 2011 OSA.

Long-Haul Transmission of PS-QPSK at 100 Gb/s using digital backpropagation
IEEE Photonics Technology Letters, 2012Co-Authors: Domani?? Lavery, Robert I. Killey, Carsten Behrens, Sergejs Makovejs, David S. Millar, Seb J. Savory, Polina BayvelAbstract:We experimentally investigate the generation and Long-Haul Transmission of polarization-switched quadrature phase shift keying (PS-QPSK) at an uncoded datarate of 112 Gbit/s (37.4 GBd). In what is the first demonstration of nonlinearity compensation for PS-QPSK, digital backpropagation is applied in order to evaluate performance improvements. We find that, even at this high symbol rate, the maximum Transmission distance of this format can be increased by 20% by employing digital backpropagation.

Ultra-Long-Haul Transmission of 7×42.9 Gbit/s PS-QPSK and PDM-BPSK.
Optics express, 2011Co-Authors: Carsten Behrens, Robert I. Killey, Domaniç Lavery, Benn Charles Thomsen, Sergejs Makovejs, David S. Millar, Seb J. Savory, Polina BayvelAbstract:We investigated ultra-Long-Haul Transmission of polarization-switched QPSK (PS-QPSK) and polarization-division-multiplexed BPSK (PDM-BPSK) at 42.9 Gbit/s experimentally as well as by means of computer simulations. PDM-BPSK allowed Transmission distances in excess of 14,040 km to be achieved, compared to 13,640 km for PS-QPSK. However, PS-QPSK offers a significant reduction in receiver complexity due to the lower symbol-rate.

Generation and Long-Haul Transmission of polarization-switched QPSK at 42.9 Gb/s.
Optics express, 2011Co-Authors: David S. Millar, Carsten Behrens, Domaniç Lavery, Benn Charles Thomsen, Sergejs Makovejs, Polina Bayvel, Seb J. SavoryAbstract:We demonstrate, for the first time, the generation and Transmission of polarization-switched QPSK (PS-QPSK) signals at 42.9 Gb/s. Long-Haul Transmission of PS-QPSK is experimentally investigated in a recirculating loop and compared with Transmission of dual-polarization QPSK (DP-QPSK) at 42.9 Gb/s per channel. A reduction in the required OSNR of 0.7 dB was found at a BER of 3.8 x 10(-3), resulting in an increase in maximum reach of more than 30% for a WDM system operating on a 50 GHz frequency grid. The maximum reach of 13640 km for WDM PS-QPSK is, to the best of our knowledge, the longest distance reported for 40 Gb/s WDM Transmission, over an uncompensated link, with standard fiber and amplification.

Journal of Lightwave Technology, 2012Co-Authors: J??r??mie Renaudier, Patrice Tran, Paolo Serena, Ha??k Mardoyan, Oriol Bertran-pardo, Massimiliano Salsi, Gabriel Charlet, Eric Dutisseuil, Alberto Bononi, Sebastien BigoAbstract:We report on an experimental Long-Haul Transmission of a 28 Gbaud PS-QPSK signal in WDM scenarios. This report presents, to the authors' knowledge, a novel implementation of an optical coherent receiver for the polarization-switched quadrature phase shift keying (PS-QPSK) modulation format, with minor variations on the standard coherent PDM-QPSK receiver. We compare the performance of PS-QPSK with that of PDM-QPSK, over a WDM system based on 100 Gb/s PDM-QPSK and standard single mode fiber (SSMF), and we demonstrate its interest for software-defined optical transceivers operating over dispersion managed and non-managed Transmission links.
