“…Higher order QAM modulation improves the spectral efficiency but at the price of higher optical SNR limit and hence shorter distance. Therefore we will need bit rate variable transponders with flexible modulation formats, tuned dynamically to the transmission distance required [110].…”

Lightwave communications is a necessity for the information age. Optical links provide enormous bandwidth, and the optical fiber is the only medium that can meet the modern society's needs for transporting massive amounts of data over long distances. Applications range from global highcapacity networks, which constitute the backbone of the internet, to the massively parallel interconnects that provide data connectivity inside datacenters and supercomputers. Optical communications is a diverse and rapidly changing field, where experts in photonics, communications, electronics, and signal processing work side by side to meet the ever-increasing demands for higher capacity, lower cost, and lower energy consumption, while adapting the system design to novel services and technologies. Due to the interdisciplinary nature of this rich research field, Journal of Optics has invited 16 researchers, each a world-leading expert in their respective subfields, to contribute a section to this invited review article, summarizing their views on state-of-the-art and future developments in optical communications.

“…Fig. 3 shows the effect on OSNR penalty of bringing sub-channels closer together for the configuration given in [4]. Here it is seen that the penalty rises sharply below about 37.5 GHz.…”

“…Transceivers are now becoming available which utilise several of these formats-even on demand [4]. The most straightforward way to take advantage of this flexibility is to use the highest QAM possible for each optical path, according to its transmission distance or OSNR.…”

“…Fig. 2 shows a super-channel, comprising 7 × DP-16 QAM sub-channels from [4], demonstrating the highest aggregate rate, real-time (i.e., NO off-line processing) super-channel transmission at that time. Also shown are various single channels coexisting on the same fibre.…”

“…the technology is capable of far more than just a single type of modulation to deliver 100 Gb/s: in fact it is expected to evolve towards a range of modulation formats, bit rates and forward error correction (FEC) (see [4] for early example of transceivers with dynamically adjustable modulation format).…”
