“…SOA1 has a small signal gain of 28 dB, a saturation input power of -16 dBm at 1 dB gain compression and a noise figure (NF) of 7 dB at 1309 nm wavelength, for bias current of 444 mA at 20°C. In our previous work [12], to avoid nonlinear effects during fiber propagation, the launched power had to be limited to 12 dBm [9]. We thus add an attenuator before the SOA to reduce the input power to -17 dBm and obtain a Tx output power of 12 dBm (Fig.…”

“…However, few reports [8] real time demonstrations due to the development cost of customized digital signal processing (DSP) chips at this bitrate. On the other hand, 100 Gbit/s with 4-level Pulse Amplitude Modulation (PAM-4) has been demonstrated with direct detection (DD) and offline DSP [9][10][11][12]. In [13], we showed that using a Mach-Zehnder Modulator (MZM) and DD, PAM-4 could be detected without DSP.…”

A 100 Gbit/s/λ PAM-4 fiber link with an optical budget of 30 dB and 20 km fiber reach is achieved in real time experiments. This is compliant with class A (20 dB) point to point (PtP) applications as mobile fronthaul for example, and with class N1 (29 dB) point to multipoint (PtMP) for residential market. We used an integrated externally modulated laser, an analog pre-equalizer, an optical booster amplifier and/or non-filtered preamplifier and direct detection without any digital signal processing (whether real-time or offline).

“…This can be done via highcapacity TDM-PONs, e.g. 100 Gbit/s PONs [26] or by using WDM-PONs with a large number of wavelengths (e.g. > 20) and at least 25 Gbit/s per wavelength.…”

Smart cities will be characterized by a variety of intelligent and networked services, each with specific requirements for the underlying network infrastructure. While smart city architectures and services have been studied extensively, little attention has been paid to the network technology. The KIGLIS research project, consisting of a consortium of companies, universities and research institutions, focuses on artificial intelligence for optimizing fiber-optic networks of a smart city, with a special focus on future mobility applications, such as automated driving. In this paper, we present early results on our process of collecting smart city requirements for communication networks, which will lead towards reference infrastructure and architecture solutions. Finally, we suggest directions in which artificial intelligence will improve smart city networks.

“…Another TDH pulse amplitude modulation (PAM) -orthogonal frequency division multiplexing (OFDM) system is reported that the data rate of multiple sub-carriers with a fixed baud rate can be flexibly changed from 40 Gb/s to 80 Gb/s using mixed on-off keying (OOK) and PAM4 signals [6]. The TDH scheme can offer some intermediate system performance [7][8]. Similarly, HM adaptively adjusts the signal quality of the two links within a group according to the user demands.…”

A Hierarchical Modulation Enabled SNR Allocable Delta-Sigma Digital Mobile Fronthaul System

Internet of everything is being build up rapidly, which causes much higher requirements towards the flexibility of communication resources, especially the adaptivity of the fronthaul to various transmission distances and capacities. In this paper, we proposed a low-cost and spectrum efficient 5G fronthaul broadband connection solution that combines hierarchical modulation technology and delta-sigma modulation. The proposed scheme can double the number of accesses without occupying extra wavelengths. Moreover, such architecture can flexibly allocate the SNR of a group of remote radio units for different user requirement of transmission rate and reaches. Simulation results show that the proposed scheme can increase the access distance of the fronthaul network by 23% and the capacity by 16.7%. The feasibility of the solution is verified through a proof-of-concept experiment. After 20 km transmission, the OFDM-64QAM and -256QAM signal with a center frequency of 3.5 GHz and a bandwidth of 500 MHz can meet the EVM requirements of 8% and 3.5%, respectively. And when the 𝐑 𝑳𝑴 of the hierarchical PAM4 signal is 0.6, the ROP required by the most-significant bit branch can be reduced by ~1.5 dB.
