We transmit 96 PDM-QPSK channels at 100Gb/s over 11,680km, matching the best capacity × distance product reported, but with C-band-only EDFAs. 2.7b/s/Hz spectral density is obtained, despite 23% super-FEC overhead, with optical spectral engineering.
We transmit two 100Gb/s PDM-QPSK data streams over two different modes of a 40km-long prototype few-mode fiber. Our experiment is performed with an LCOS-based mode multiplexer/demultiplexer and 4×4 MIMO algorithm in a coherent receiver.
A model for nonlinear propagation over bimodal fiber is proposed. Through numerical simulations, the tolerance to nonlinear effects of Mode Division Multiplexing (MDM) is estimated using the example of a 7×200Gb/s WDM MDM-QPSK transmission over 1200km.
A transoceanic transmission at 100Gbit/s is demonstrated with EDFA repeaters only. The result was obtained with coherent detection, ultra low-loss large effective area fiber, and PDM-QPSK modulation format.
We investigate the impact of the transmitter bandwidth on the nonlinear tolerance in a 112-Gb/s polarization-division-multiplexed quaternary phase-shift keying system with coherent detection over a 1200-km dispersion-managed link using standard single-mode fiber. We show that a narrower transmitter bandwidth degrades not only the noise tolerance, but also exacerbates signal degradations due to nonlinearities...
We demonstrate, over a NZDSF link, that the system benefits provided by the temporal interleaving of polarization tributaries of 100 Gb/s coherent RZ-PDM-QPSK data depend on the WDM system configuration.
We report the transmission of 155 channels with 100Gbit/s PDM-QPSK modulation over 7200km of pure silica core fibre, exploiting hybrid Raman-EDFA amplification and digital coherent detection. A record 112Petabit/s·km capacity×distance product is demonstrated.
