“…The fit in Figure 9 uses σ G = 0.7 dB and K being the number of 55 km spans, leading to a good agreement between experimental data and the fit. We further observed an almost constant ratio between the system MDL and σ MDL , which is in accordance with previous observations [14], [13]. Figure 10 shows the system MDL of all 348 spatial super channels after 1045 km transmission.…”

We experimentally investigate high-capacity fewmode fiber transmission for short and medium-haul optical links. In separate experiments, we demonstrate C + L band transmission of 283 Tbit/s over a single 30 km span and 159 Tbit/s over 1045 km looped transmission in a graded-index three mode fiber. The first experiment reached a data-rate per fiber mode within 90% of the record data-rates reported in the same transmission bands for single-mode fiber. The second experiment demonstrated the feasibility of reaching high data-rates over long distance few-mode fiber transmission, despite strong impairments due to mode-dependent loss and differential mode delay.

“…The MC and MM strategies have been widely investigated and numerous hero experiments have been reported. For instance, capacity in excess of 138 Tb/s with MM [6] or up to 1 Pb/s with MC [7] has been achieved. Such strategies would greatly contribute to address the capacity crunch, but they present several important limitations, as listed in Fig.…”

“…It uses the same number of receivers (single-ended photo-diodes) as coherent receivers (balanced photo-diodes) but eliminates the 90-degree optical hybrids and the LO. Performing the phase recovery on both received polarizations or multiple received spatial modes allows the phase-retrieval receiver to act analogously to a standard coherent receiver supporting both polarization-division multiplexing and spacedivision multiplexing [28] using only direct detection. As a demonstration, we measure a polarization-multiplexed 30-Gbaud QPSK signal after 520-km single-mode fiber (SMF) transmission with a line rate of 120-Gbit/s, which has accumulated strong polarization scrambling (PMD) and CD.…”

Conventional optical coherent receivers capture the full electrical field, including amplitude and phase, of a signal waveform by measuring its interference against a stable continuous-wave local oscillator (LO). In optical coherent communications, powerful digital signal processing (DSP) techniques operating on the full electrical field can effectively undo transmission impairments such as chromatic dispersion (CD), and polarization mode dispersion (PMD). Simpler direct detection techniques do not have access to the full electrical field and therefore lack the ability to compensate for these impairments. We present a full-field measurement technique using only direct detection that does not require any beating with a strong carrier LO. Rather, phase retrieval algorithms based on alternating projections that makes use of dispersive elements are discussed, allowing to recover the optical phase from intensityonly measurements. In this demonstration, the phase retrieval algorithm is a modified GerchbergSaxton (GS) algorithm that achieves a simulated optical signal-to-noise ratio (OSNR) penalty of less than 4 dB compared to theory at a bit-error rate of 2×10 −2 . Based on the proposed phase retrieval scheme, we experimentally demonstrate signal detection and subsequent standard 2×2 multiple-input-multiple-output (MIMO) equalization of a polarization-multiplexed 30-Gbaud QPSK transmitted over a 520-km standard single-mode fiber (SMF) span.
