“…The relatively high noise figure of SOAs versus, for example, EDFAs means they are generally considered unsuitable for repeatered transmission systems. Nevertheless, by combining an SOA with distributed backward Raman amplification, 107 Tbit/s transmission over 300 km (3⇥100 km) was reported in [4]. 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].…”

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.

“…As shown in Fig. 1, which summarizes transmission experiments exceeding 100 Tb/s in 125 µm diameter fibers, we report transmission in a 4-core fiber [24] with per-core throughputs exceeding the highest reported in SMF to date [25]- [28] and exceeding the previous record throughput for a 125 µm diameter MCF [29] by more than 5 times. Wideband transmission is achieved by using a single extended bandwidth frequency comb [30] generated from a seed laser that may also be transmitted across networks through MCF cores for comb regeneration [31].…”

“…We note that with an improved comb or adopting alternative transmitter lasers additional data throughput could be obtained by utilizing S-band channels in the region below 1490nm where TDFA bandwidth remains and from extending the high wavelength cut-off to reduce the size of the guard band between S-and C-bands. Further improvement could also be achieved by adopting continuous SOA amplifiers utilized in previous wideband transmission demonstrations [27], [28]. Finally, we note that increased throughput and potentially higher-order modulation, could be achieved with optical components better optimized for S-band transmission, thus highlighting the challenges of adopting new optical fiber transmission windows.…”

We investigate high-throughput, multi-band transmission in a 4-core multi-core fiber (MCF) with the same 125 µm cladding diameter of standard single-mode fiber (SMF). A single wideband comb source is used to transmit up to 561 wavelength channels with 25 GHz spacing over a 120 nm bandwidth in S, C and L bands. We demonstrate a maximum decoded throughput of 610 Tb/s in PDM-256QAM and PDM-64QAM signals over a 54 km fiber, with a per-core average throughput exceeding wideband transmission demonstrations in single-mode fibers and highest single core throughput of 155.1 Tb/s. In addition, we use noise loading measurements to characterize the achievable signal quality across the wideband transmitter. These results show that a single comb source can enable high-spectral efficiency modulation over wide bandwidths and further that low-core count homogeneous MCFs technology can offer the same transmission performance as single-mode fibers without sacrificing mechanical reliability, and still offering the benefits of shared resources and greater efficiency that drives SDM technologies.

“…Although the bandwidth is notable, SOAs have a relatively high noise figure compared with EDFAs and distributed Raman amplifiers, so the system performance decreases rapidly with distance. Through the combination of SOA and distributed backward Raman amplifier, 107 Tbit/s transmitted over 300km (3x100km) was demonstrated in [9]. Higher data throughput of 120 Tbit/s over 630 km (9x70km) was achieved by using continuous 91 nm hybrid distributed Raman-EDFA amplifier [10] [11].…”
