“…e FOCS performance is impaired by another key limiting factor known as POaN. It happens when several wavelengths travel over an SMF with same phase angle but reaches at the other end with a phase offset [27] due to the reflections and refraction from core and cladding. As a result, the transmitted optical pulses face phase offset and related phase noise [28].…”

Fiber optic communication systems (FOCSs) have attained a lot of attention by revolutionizing the telecommunication industry and offering new possibilities with the technical advancements in state-of-the-art high speed digital electronics. Advanced modulation formats make use of the phase, amplitude, and polarization of the optical signals at the same time to provide high spectral efficiency as compared with 1 bit/s/Hz for the intensity modulation direct detection system (IMDD), but are highly prone to transmission impairments. Thus, the effects that add up to the optical fiber impairments such as optical fiber chromatic dispersion (OFCD), polarization model dispersion (PMD), and phase offset and noise (POaN) need to be addressed at the receiver side. The development of components and algorithms to minimize these effects in next generation FOCSs with 100 Gbps data rate and beyond with long-haul transmission is still a challenging issue. In this paper, digital signal processing- (DSP-) assisted dispersion and nonlinear compensation techniques are presented to compensate for physical layer impairments including OFCD, PMD, and POaN. The simulations are performed considering Dual Polarization- (DP-) QPSK modulation format to achieve two-fold data rate to achieve spectral efficiency of 3.28 bits/s/Hz by making use of the polarization diversity and system performance is investigated in terms of bit error rate (BER), constellation diagrams, and quality factor (Q-factor) for different values of optical signal-to-noise ratio (OSNR), launch power (PL), and fiber length.

“…Two major problems can be encountered in MGM schemes, namely mode partition noise (MPN) at the receiver and frequency selective fading resulting from intra-MG DMD [86]. MPN can be dealt with by simultaneously detecting all the intra-group modes [19,20], but the fading resulting from the intra-group DMD cannot be eliminated by schemes such as single-side band modulation [84,28] [40,[87][88][89]. In these experiments, simultaneous detection of all the intra-MG modes was realized using weighted composite phase masks to avoid the mode partition noise.…”

“…Mode group multiplexing (MGM) is another MIMO-free MDM transmission scheme, in which multiple (near-)degenerate modes within each MG of a GI-MMF are regarded as one data channel. By exploiting weak-coupling among different MGs, MIMO processing can be eliminated [17][18][19][20]. However, as the number of modes in each MG increases with the MG order, reception of high-order MGs will become more complicated, since all the intra-group modes need to be detected simultaneously at the receiver in the MGM scheme to avoid mode partition noise [19,20].…”

The unique modal characteristics of ring core fibres potentially enable the implementation of mode-division multiplexing (MDM) schemes that can increase optical data transmission capacity with either low complexity modular multiinput multi-output (MIMO) equalization or no MIMO. This paper attempts to present an comprehensive review of recent research on key aspects of RCF-based MDM transmission. Starting from fundamental fibre modal structures, a theoretical comparison between RCF and conventional step-index and graded-index multi-mode fibres in terms of their MDM capacity and the associated MIMO complexity is given first as the underlining rationale behind RCF-MDM. This is followed by a discussion of RCF design considerations for achieving high mode channel count and low crosstalk performances in either MIMO-free or modular MIMO transmission schemes. The principles and implementations of RCF mode (de-)multiplexing devices are discussed in detail, followed by RCF-based optical amplifiers, culminating in MIMOfree or modular MIMO RCF-MDM data transmission schemes. A discussion on further research directions is also given.

“…1(a)], reception of high-order MGs will become increasingly complex, when mode demultiplexer that demultiplexes all intra-group modes is utilized. The MG (de)multiplexer [15] can help address this issue. However, relatively higher crosstalk between adjacent higher-order MGs in the MG (de)multiplexer and optical fibers limits scalability of the MMFbased MGM systems to high-order MGs.…”

An orbital-angular-momentum (OAM) mode-group multiplexing (MGM) scheme using high-order mode groups (MGs) in a graded-index ring-core fiber (GIRCF) is proposed, in which a receive-diversity architecture is designed for each MG to suppress the mode partition noise resulting from random intra-group mode crosstalk. The signal-to-noise ratio (SNR) of the received signals is further improved by a simple maximal ratio combining (MRC) technique on the receiver side to efficiently take advantage of the diversity gain of the receiver. Intensity-modulated direct-detection (IM-DD) systems transmitting three OAM mode groups with total 100-Gb/s discrete multi-tone (DMT) signals over a 1-km GIRCF and two OAM mode groups with total 40-Gb/s DMT signals over an 18.4-km GIRCF are experimentally demonstrated, respectively, to confirm the feasibility of our proposed OAM-MGM scheme.
