TL;DR: Single-laser 32.5 Tbit/s 16QAM Nyquist-WDM transmission with 325 carriers over 227 km at a net spectral efficiency of 6.4 bit/s/Hz is reported.

TL;DR: Heterogeneous subscribers having widely varying needs with respect to power and band-width can be effectively controlled and optically supplied by a central of-fice using a novel low-energy medium access control protocol.

TL;DR: Inexpensive fiber optics and low-power state-of-the-art electronics are used to make >100 mW available at sites which have no direct access to an electrical network.

TL;DR: In this article, the quality of optical signals is a very important parameter in optical communications Several metrics are in common use, like optical signal-to-noise power ratio (OSNR), Q-factor, error vector magnitude (EVM) and bit error ratio (BER), which are used to predict the final BER after soft-decision forward error correction (FEC), if the statistics of the noise leading to errors is unknown.

TL;DR: In this article, the authors demonstrate 32.5 Tbit/s 16QAM Nyquist WDM transmission over a total length of 227 km of SMF-28 without optical dispersion compensation.
