“…Apart from the fact that the presented work in [14] was brief, some salient concepts of the simplified transceivers such as carrier/SSB signal generation, SSBN mitigation, spectral broadening, CSPR optimization, and field and polarization recoveries were not discussed. Moreover, the great majority of the contributions focused on one-or two-optical-SSB-signal generation [12,[53][54][55][56], while most also presented one or two SSBN mitigation/digital linearization schemes [12,21,22,29,30,46,54,[57][58][59]. Furthermore, in [55,56], the SSB signal generation was well presented, while little or no consideration was given to the SSBN mitigation/digital linearization schemes.…”

This paper reviews recent progress on different high-speed optical short- and medium-reach transmission systems. Furthermore, a comprehensive tutorial on high-performance, low-cost, and advanced optical transceiver (TRx) paradigms is presented. In this context, recent advances in high-performance digital signal processing algorithms and innovative optoelectronic components are extensively discussed. Moreover, based on the growing increase in the dynamic environment and the heterogeneous nature of different applications and services to be supported by the systems, we discuss the reconfigurable and sliceable TRxs that can be employed. The associated technical challenges of various system algorithms are reviewed, and we proffer viable solutions to address them.

“…Unlike the first approach, a digital SSB filter based on Hilbert transformation is adopted at the transmitter (Tx) of the second approach, the representative of which is regarded as SSB SCM scheme in the recent research [33], [34]. This scheme employs an in-phase quadrature modulator (IQM) or dual-drive Mach-Zehnder modulator (DDMZM) to map SSB digital signal linearly into the optical field [35]. The third approach with an optical carrier added to the edge of signal spectrum can generate an optical carrier-assisted SSB (OCA-SSB) signal [28].…”

Recently, high-speed optical transmission using single-side-band (SSB) modulation with Kramers-Kronig (KK) scheme has gained great attention due to its high spectral efficiency (SE) and capability of electronic chromatic dispersion compensation (CDC), which can be widely employed in optical metro networks as a promising transmission scheme. To our knowledge, the carrier-signal power ratio (CSPR) is the key parameter to SSB-based systems and the optimum CSPRs can vary distinctly in different SSB modulation schemes. In this paper, the SSB-based KK systems with four kinds of SSB signal generation schemes are investigated, i.e. optical carrier-assisted SSB (OCA-SSB), virtual carrierassisted SSB (VCA-SSB), SSB subcarrier modulation (SSB SCM) with IQ modulator (IQM) and with dual-drive Mach-Zehnder modulator (DDMZM) respectively. Here, the detailed theoretical derivations of these modulation processing are given and the theoretical relationship between device parameters and the CSPR has been further studied for the different SSB schemes. In order to verify those theoretical analyses, a 224-Gb/s direct detection (DD) transmission with SSB 16-ary quadrature amplitude modulation (16-QAM) signal has been demonstrated based on four SSB generation methods. The results show that theoretical derivations are closely consist with numerical analysis, such as V bias in the scheme of SSB SCM with IQM and optical modulation index (OMI) in SSB SCM with DDMZM. Therefore, our research can provide a theoretical guidance of appropriate device parameter configuration so as to achieve the optimum performance for SSB systems.
