42.8 Gbit/s, 4 bits per symbol 16-ary Inverse-RZ-QASK-DQPSK transmission experiment without Polmux

We present an experimental implementation of 16-ary 42.8 Gbit/s Inverse-RZ-QASKDQPSK, using four-level inverse return-to-zero amplitude modulation with four-level differential phase modulation. We demonstrate transmission over a 75 km fibre span with only minor degradation

Jean-Julien Bourgault : Maître d'oeuvre et maître à penser

Multilevel modulation formats are used as the enabling technology to obtain 120 Gbit/s per channel bit rates, and 240 Gbit/s when polarisation multiplexing is added. Using OTDM, this can be extended even further

Effects of resveratrol on high-fructose-induced testis injury in rats

This study investigated whether a high-fructose (HFr) diet changes the morphology of seminiferous tubules (ST) in rats and resveratrol (RES) has a possible restoring effect in this sense. Fructose (30%; w/v) was administered to rats alone or together with RES (50 mg/L) in drinking water for 8 weeks. In the HFr group, destruction of the germinal epithelium led to the detection of immature germ cells in the lumen. HFr diet gave rise to a decrease in the ST diameters (p < 0.05), Johnsen's tubular biopsy score values (p < 0.001), and an increase in the apoptotic index (p < 0.05). Ultrastructurally, HFr feeding increased lipid accumulation (p < 0.01), mitochondrial damage, and acrosomal abnormalities in spermatogenic cells. Treatment of HFr-fed rats with RES improved the reduced ST diameters and overall general histological and ultrastructural abnormalities of the STs, but did not change the increased apoptotic index

Coding gain of FEC encoded 21.42Gb/s RZ/DQPSK using an electrical differential quaternary precoder

We report a measured gross coding gain of 6.8dB for 21.42Gb/s RZ-DQPSK using standard FEC in combination with differential precoding. Furthermore we show that RZ-DQPSK has approximately a 2dB higher FEC coding gain than RZ-DPSK

10,200km 22x2x10Gbit/s RZ-DQPSK dense WDM transmission without inline dispersion compensation through optical phase conjugation

Using optical phase conjugation with a polarization independent periodically-poled lithium-niobate subsystem, we demonstrate dense WDM 2x10Gbit/s RZ-DQPSK transmission over 10,200km of SSMF with a record accumulated dispersion, exceeding 80,000ps/nm
