TL;DR: This work shows transmission of 20 wavelength-division-multiplexed (WDM) × 960-Gb/s space- division- multiplexed 32QAM modulated channels (spectral efficiency of 15 bits/s/Hz) with inline few-mode EDFA (FM-EDFA) with Soft-decision FEC to achieve error-free transmission.

TL;DR: Three possible scenarios for upgrading current single-mode transmission networks with high capacity few-mode fiber technology using mode-division multiplexing (MDM) are demonstrated.

TL;DR: Based on a three-surface prism, a free space design of the three-spot mode coupler, supporting LP01 and LP11 modes, is introduced in this paper, where the authors demonstrate 7.68 Tbit/s transmission of three mode division multiplexing (MDM) × 8 wavelength division multiple Xing (WDM), × 320-Gb/s dual-polarization (DP)-32QAM over a 120 km differential-group-delay (DGD)-compensated few-mode fiber (FMF) by employing the proposed spot coupl

TL;DR: In this article, an overview of self coherent optical (SCO-) OFDM is given, where the optical carrier is extracted from the signal with the use of filters with very narrow bandwidth and used as an LO using heterodyne or homodyne detection.

TL;DR: It is reported for the first time coherently-detected, polarization-multiplexed transmission over photonic band gap fiber by transmitting 96 × 320-Gb/s DP-32QAM modulated channels, with a net data rate of 24 Tb/s.
