Kim Roberts et al. Performance of Dual-Polarization QPSK for Optical Transport Systems

Joual of Lightwave Technology, vol. 27, No. 16, August 15, 2009.

Abstract—The emergence of capable semiconductor processes
has allowed digital signal processing to extend the application
range of high-capacity optical systems. We report the performance
of polarization multiplexed (or dual-polarization) quadrature
phase-shift keying at 40 and 100 Gb/s.

Index Terms—Electronic signal processing, optical coherent
transceiver, polarization multiplexing, quadrature phase-shift
keying (QPSK).

Optical Switching and Networking 6 (2009) 10–19. Abstract. The problem of lightpath topology design (LTD) and traffic routing over the lightpaths for. wavelength-routed optical backbone networks has been investigated extensively in the. past using heuristic as well as linear-programming based approaches. Sensitivity of such. long-haul backbones to physical-layer impairments is required to be adequately addressed. during LTD phase to improve overa...

Journal of lightwave technology, Vol. 29, No. 4, February 15, 2011. Abstract — We discuss the generation, wavelength-division-multiplexed (WDM) long-haul transmission, and coherent detection of 224-Gb/s polarization-division-multiplexed (PDM) 16-ary quadrature amplitude modulation (16-QAM) at a line rate of 28 Gbaud. We measure a required optical signal-to-noise ratio of 23.4 dB (0.1-nm reference bandwidth; 10^-3 bit-error ratio), 3.4-dB off the...
