“…It was shown that the optimal radii highly depend on the transmit power. In [30], the SEP of M -PSK was studied assuming a minimum-distance detector. In [14], a capacity analysis is presented for fiber-optical channels.…”

Abstract-We study the design of amplitude phase-shift keying (APSK) constellations for a coherent fiber-optical communication system where nonlinear phase noise (NLPN) is the main system impairment. APSK constellations can be regarded as a union of phase-shift keying (PSK) signal sets with different amplitude levels. A practical two-stage (TS) detection scheme is analyzed, which performs close to optimal detection for high enough input power. We optimize APSK constellations with 4, 8, and 16 points in terms of symbol error probability (SEP) under TS detection for several combinations of input power and fiber length. For 16 points, performance gains of 3.2 dB can be achieved at a SEP of 10 −2 compared to 16-QAM by choosing an optimized APSK constellation. We also demonstrate that in the presence of severe nonlinear distortions, it may become beneficial to sacrifice a constellation point or an entire constellation ring to reduce the average SEP. Finally, we discuss the problem of selecting a good binary labeling for the found constellations.

“…Signal constellation design and detection assuming the same channel as here has been studied previously in [28]- [30]. In [28], the authors applied several predistortion and postcompensation techniques in combination with minimum-distance detection for quadrature amplitude modulation (QAM) to mitigate the effect of NLPN.…”

“…To investigate network assurance involving automated fault detection, a transport SDN (TSDN)-integrated cognitive fault detection architecture, incorporating data analytics based on advanced ML methods have been proposed [67]. To mitigate NLPN [68], commonly used conventional approaches are the maximum likehood estimation (MLE) [69] and digital back-propagation (DBP) algorithms [70]. These approaches depend on the fixed fiber link information, which are not efficient in dynamic and reconfigurable optical network conditions.…”

The interconnection of all things is developing a new diagram of future information networks. However, it is difficult to realize future applications with only one single technique. Collaboration between multiple advanced techniques is leading the way for the development of future information networks. Optical communication is an enabling technique to achieve high speed, long reach, and low latency communication, which plays an important role on the transformation of information networks. To achieve these advantages that caters to the characteristics of future information networks, collaboration of multiple advanced techniques with optical, which is called "optical plus X", could realize the vision of "all things connected with networks". In this paper, we focus on the collaboration between optical networks with other techniques, mainly discuss four representative aspects, which are "optical plus IP", "optical plus radio", "optical plus computing", and "optical plus AI". We discuss the challenges, timely works, and developing trends. Finally, we give the future visions for optical network towards a collaborative, converged and co-automatic optical network. Keywords 5G optical transport networks, edge computing optical networks, IP over optical networks, AI-assisted optical networks, 3C optical networks

“…Clearly, the migration to coherent systems represented a major breakthrough in data transmission rates. Digital coherent systems, in addition to present an improved receiver sensitivity, they enable to recover both phase and polarization information, thus allowing compensation of chromatic dispersion (CD) [5], polarization mode dispersion (PMD) [6], rotation of the SoP [7] , and linear phase noise [8] in a novel and more efficient way. Nonlinear distortion, nevertheless, remains as an unresolved issue and, its interplay with additive noise still poses an upper bound to the capacity-range product of the Campus São João da Boa Vista, Universidade Estadual Paulista "Júlio de Mesquita Filho" -Unesp, São João da Boa Vista -SP, e-mails: lucio.borges@unesp.br, cb.costa@unesp.br, romulo.junior314@yahoo.com.br, marcelo.abbade@unesp.br, and ivan.aldaya@unesp.br.…”

This work analyzes the use of the K-means clustering algorithm to mitigate nonlinear phase noise in singlespan coherent systems, such as long-reach passive optical networks (LR-PONs). Simulations revealed that for a 100-km LR-PON employing 16-ary quadrature amplitude modulation (QAM) and considering a 1:64 splitting ratio, the adoption of K-means with K-means++ initialization achieves an optimum bit error ratio (BER) of 6.3 • 10 −4 , whereas employing maximum likelihood, 10 −3 is obtained. We also show that in order to achieve this performance improvement in 90% of the cases, K-means requires only 2,000 symbols.
