“…These include distributed Raman amplification, erbium doped fibre amplifiers (EDFA), semiconductor optical amplifiers (SOA), and combinations thereof. Aside from [7], where a capacity of 74 Tbit/s over 6300 km was achieved using a hybrid distributed Raman/EDFA (HRE) amplification scheme, all trans-Atlantic (> 6000 km) and trans-Pacific (> 9000 km) record data rates to date have been reached by using C+L band EDFAs [10]. Despite HRE schemes having a lower noise figure compared with EDFAs, this amplification technology is not as power efficient as EDFA systems, which makes it less attractive for long-haul submarine systems that are electrical power feed constrained.…”

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.

“…Extending the wavelengths to the L-band yields at most a factor of two in the throughput, reaching ∼70 Tb/s for ∼7000-km transmission [181]. Using S-, C-, and L-bands, the achieved link throughput is seen to increase to 74 Tbs/s for 6300-km transmission [190] and 115 Tb/s for 100-km transmission [173] (with the S-band emulated by ASE noise). Higher rates have been demonstrated for shorter distances [209].…”

“…In this section, we review hero fiber-transmission experiments. In the first part, we focus on systems ranging from metro to transoceanic distances [167], [168], [169], [170], [171], [172], [173], [174], [175], [176], [177], [178], [179], [180], [181], [182], [183], [184], [185], [186], [187], [188], [189], [190], [191], [192], [193], [194], [195], [196], [197], [198], [199], [200], [201], [202], [203], [204], [205], [206], whereas, in the second part, we review shorter links where high-speed transmission happens primarily for datacenter interconnect applications [207], [208], [209], [210], [211], [212],…”

Challenges in Estimating the Information Capacity of the Fiber-Optic Channel

et al. 2022

Since its early commercial deployment in the late 1980s, optical fiber has evolved to become the predominant carrier of the globe's communications. Yet, after accommodating the world's exponentially growing appetite for transmitted data for more than three decades, its ability to continue doing so is being challenged by fundamental factors. In this article, we review these factors and examine their consequences in terms of information capacity. In particular, we review the difficulties that are imposed by the nonlinear nature of fiber-optic transmission on the assessment of the capacity and on the definition of fundamental concepts, such as bandwidth and spectral efficiency. We discuss relevant approximations and regimes of operation in which bounds for the capacity can be effectively assessed while covering a broad range of applications ranging from interdatacenter communications to links spanning transoceanic distances. We relate to a broad variety of transmission schemes and discuss the potential benefits of spatial multiplexing with multimode and multicore fibers.State-of-the-art transmission experiments are also reviewed and compared with theoretical capacity bounds.

“…Esta evolução, por meio do processamento digital de sinais, proporcionou a compensação de forma eletrônica dos efeitos lineares da dispersão cromática (CD) e da dis-persão modo de polarização (PMD), além dos efeitos nãolineares relacionados ao coeficiente Kerr [10]. O emprego de amplificadores híbridos, técnicas de processamento de sinais e modulações de formato geométricos por multiplexação por divisão de polarização, possibilitou a demonstração de uma transmissão ao longo de 6300 km a uma taxa de 74, 38 Tbps nas bandas C e L de amplificação óptica [11]. A evolução destas redes OTN também ocorreu nos dispositivos de comutação com o emprego de comutadores seletivos de comprimentos de ondas (WSS) e os comutadores OTN responsáveis pelas conexões cruzadas entre enlaces de longas distância e as redes metropolitanas.…”
