“…For instance, while the O-band could carry short-reach traffic, e.g., ≤ 80 km, long-haul (LH) traffic could be transported on the better performing C-or L-bands. In this context, a first assessment on the MBT potentialities, performing an iterative power optimization scheme for C-, S-and L-band, has been proposed in [38], [39]. In [38], a 150 Tb/s capacity has been shown after 40 km by using S-, C-and L-bands.…”

Fiber-optic multi-band transmission (MBT) aims at exploiting the low-loss spectral windows of single-mode fibers (SMFs) for data transport, expanding by ∼11× the available bandwidth of C-band line systems and by ∼5× C+L-band line systems'. MBT offers a high potential for cost-efficient throughput upgrades of optical networks, even in absence of available dark-fibers, as it utilizes more efficiently the existing infrastructures. This represents the main advantage compared to approaches such as multi-mode/-core fibers or spatial division multiplexing. Furthermore, the industrial trend is clear: the first commercial C+L-band systems are entering the market and research has moved toward the neighboring S-band. This article discusses the potential and challenges of MBT covering the ITU-T optical bands O → L. MBT performance is assessed by addressing the generalized SNR (GSNR) including both the linear and non-linear fiber propagation effects. Non-linear fiber propagation is taken into account by computing the generated non-linear interference by using the generalized Gaussian-noise (GGN) model, which takes into account the interaction of nonlinear fiber propagation with stimulated Raman scattering (SRS), and in general considers wavelength-dependent fiber parameters. For linear effects, we hypothesize typical components' figures and discussion on components' limitations, such as transceivers', amplifiers' and filters' are not part of this work. We focus on assessing the transmission throughput that is realistic to achieve by using feasible multi-band components without specific optimizations and implementation discussion. So, results are meant to address the potential throughput scaling by turningon excess fiber transmission bands. As transmission fiber, we focus exclusively on the ITU-T G.652.D, since it is the most widely deployed fiber type worldwide and the mostly suitable to multi-band transmission, thanks to its ultra-wide low-loss singlemode high-dispersion spectral region.

“…A yet greater data rate of 120 Tbit/s over 630 km (9⇥70 km) was shown by using hybrid distributed Raman-EDFA amplifiers with a continuous 91 nm gain bandwidth [5]. Extending the transmission bandwidth to S-band wavelengths resulted in the highest single mode fibre capacity experimentally shown to date of 150.3 Tbit/s, transmitted over 40 km [1] This experiment [1] used a distributed backward Raman amplification scheme for the S-band and EDFAs for C-and L-bands; with the transmitted signal occupying a total bandwidth of approximately 109 nm (13.625 THz). However, the gain bandwidth was not continuous, with approximately 17 and 5 nm spectral gaps between S/C-and C/L-bands, respectively.…”

The maximum data throughput in a single mode optical fibre is a function of both the signal bandwidth and the wavelength-dependent signal-to-noise ratio (SNR). In this paper, we investigate the use of hybrid discrete Raman & rare-earth doped fibre amplifiers to enable wide-band signal gain, without spectral gaps between amplification bands. We describe the widest continuous coherent transmission bandwidth experimentally demonstrated to date of 16.83 THz, achieved by simultaneously using the S-, C-and L-bands. The variation of fibre parameters over this bandwidth, together with the hybrid amplification method result in a significant SNR wavelengthdependence. To cope with this, the signal was optimised for each SNR, wavelength and transmission band. By using a system-tailored set of geometrically shaped constellations, we demonstrate the transmission of 660⇥25 GBd channels over 40 km, resulting in a record single mode fibre net throughput of 178.08 Tbit/s. Index Terms-Broadband transmission system, high order modulation format, geometric shaping.

“…Although the bandwidth is notable, SOAs have a relatively high noise figure compared with distributed Raman amplifiers, so the system performance decreases rapidly with distance. High data throughput in [5] [6] and [7] was achieved by using continuous 90 nm hybrid distributed Raman-EDFA amplifier with data throughput of 120 Tbit/s over 630 km demonstrated in [7] and an overall record throughput of 150.3 Tbit/s over 40 km span [8], achieved by transmitting the signals in the S, C and L-bands.…”

We experimentally demonstrated the transmission of 312⇥35 GBd DP-256QAM over 9⇥70 km spans using hybrid distributed Raman-EDFA (HRE) amplifiers with a continuous 91 nm gain bandwidth. A total throughput of 120 Tbit/s over 630 km is demonstrated, with a net achievable information rate after SD-FEC of 10.99 bit/symbol. An extensive, theoretical investigation of the noise contributions originating from amplifier, transceiver sub-system and fiber nonlinearity were carried out using the Gaussian noise model in the presence of inter-channel stimulated Raman scattering (ISRS GN model). The ISRS GN model accounts for arbitrary, wavelength dependent signal power profiles along fiber spans, which is vital for the modeling of ultra-wideband transmission, particularly for hybrid Ramanamplified links. The analysis serves to quantify the relative noise contributions and explain the performance achieved. It was found that, due to the low noise HRE amplifier and a transmission distance of 630 km, the noise originating from the transceiver sub-system imposed a penalty of 6 dB in SNR. For this system, the transceiver noise is, therefore, the main limitation to the system throughput.Index Terms-Hybrid Raman-EDFA amplifier, broadband transmission system, high order modulation format, adaptive rate LDPC decoder.
