“…Recently, successful coherent transmission in the E-band has been reported solely using BDFAs [23], [24], with the latter work featuring transmission of 143 channels over the ESCL-bands aided by a wide-band Raman amplifier. In these experimental studies, full spectral load transmission is performed in the SCL-bands, but only 4 channels are transmitted in the E-band, a limitation that arises from a lack of optical components in the E-band, especially wavelength selective switches (WSSs).…”

“…In this work, we expand upon the experimental study in [24], performing 195 nm transmission of 150x30 Gbaud dual polarisation (DP) 16-QAM signals through 70 km of standard single-mode fiber (SMF), using BDFA amplification in the E-band, and a discrete Raman amplifier (DRA) in the SCL-bands. We then present a wideband model based on a disaggregated derivation of the Gaussian noise (GN) model [27], providing generalized signal-to-noise ratio (GSNR) estimations for an envisaged ESCL-band transmission scenario operating under full spectral load.…”

Ultra-wideband transmission utilizes bandwidths beyond the standard C-band to enable significant network capacity upgrades. Upgrading the standard C-band to a C+Lband transmission scenario is already feasible, and exploratory transmission is being performed in the S-, E-, and O-bands to investigate quality of transmission (QoT) impairments in these spectral regions. In this paper, experimental transmission through a SCL-and partial E-band spectral region is performed, with use of a hybrid amplifier that exploits discrete Raman amplification for the SCL-bands, and a bismuth-doped fiber amplifier (BDFA) for the E-band. Through this transmission bandwidth, we demonstrate that 36 Tbit/s transmission is possible, with 150 coherent channels over 70 km of standard, single-mode fiber. This result is compared to a wideband physical layer model that considers a realistic full spectral load transmission scenario, where the E-band is occupied by 74 channels, providing a total of 221 channels. This comparison demonstrates that, for both scenarios in this experiment, the greatest impairment is present within the S-band, and the addition of the E-band to a SCL-band scenario has a negligible impact upon the QoT within the C-and L-bands.

“…Bismuth-doped, Bi/Er co-doped, and quantum dot-doped glasses and fibers can produce ultra-wideband fluorescence covering 1050-1800nm, making them potential gain media for ultra-wideband or even full-band fiber lasers. This widens the utilization of quartz fibers in low-loss communication and expands transmission bandwidth [2,11,12].…”

Rare-earth doped fibers are an important means of expanding the wavelength band of optical fibers. Currently, researchers aim to broaden the working wavelength band of optical fibers by doping with different rare-earth elements, thereby increasing the amount of information that can be transmitted. In this paper, a bismuth-doped fiber laser operating around 1300nm was designed. A basic physical model for implementing a bismuth-doped fiber laser was proposed based on the energy levels and transition processes of bismuth, rate, and power propagation equations. It was possible to determine the link between pump power and laser power at a wavelength of 1300 nm by modeling tests using the physical model. Additionally, the relationship between pump light and laser power in bismuth-doped fiber at different positions and propagation directions was analyzed. Suggestions for the future large-scale application of bismuth-doped fiber lasers around the 1300nm wavelength band were provided.
