We show experimental results on the transmission of a Terabit superchannel, consisting of 10×120-Gb/s PM-QPSK densely-packed subcarriers. We reached 10000km with 1.1×Baud-rate subcarrier spacing and 9000km with Baud-rate subcarrier spacing. We also reached 8000km with 3 superchannels at 1.1 spacing.
We investigate the impact of ultra-narrow carrier spacing on the transmission of a 1Tb/s superchannel comprising 10 ?? 100 Gb/s PM-QPSK carriers. We demonstrate 2200 km over installed SMF fibre with a carrier spacing of 1.1 the Baud rate.
We carried out an off-line 10.7 Gb/s transmission experiment over installed fiber, using narrow-filtered duobinary and a noise-correlation-sensitive MLSE receiver. We achieved MLSE-systems record distance (1300 km, 2048 states) and record efficiency (800 km, 64 states).
In this paper, we analyze the performance of IMDD-NRZ ASE-noise-limited systems using MLSE receivers in the presence of CD and DGD. We study the performance of different approximated branch metrics and compare them to the optimum metric evaluated using the Karhunen-Loeve (KL) method. We specifically concentrate on the SQRT metric, because of its low complexity and potential ease of channel estimation...
Recent results indicate that high-complexity MLSE processors could recover large amounts of chromatic dispersion. We propose a new branch metric that minimizes complexity while preserving very good performance.
