“…Note that our measurements relied on single Er-fiber with a length of 4 m in comparison with 15 m in [23]. The article [28] presented a simulation scheme for a WDM-PON 70 km length optical path and a 1:32 split ratio.…”

“…Mainly are focused on the measurement of signal amplification parameters. These works, however, do not consider remote amplification and need active power supply in ODN hence these types of networks are not fully passive yet [26] [28]. There are also some experiments describing the specific application of Erbiumdoped fiber (EDF) and laser pump diodes.…”

A remotely pumped Erbium-doped system for the amplification of an optical signal for long-reach (LR) next-generation passive optical networks (NG-PONs) is presented in this paper. The next-generation networks will be deployed with/over the current point to multi-point technology with/without backward compatibility. Remote pumping allows extending the reach of the optical distribution networks and the magnification of the splitting ratio as well, which is most important for increasing the number of end users in the PON network. In our laboratory, we have successfully verified the functionality of the unidirectional and bidirectional remote pumping system based on an Erbium-doped fiber inserted into the route and remote pumping from a central office. Our measurement results prove that it is possible to extend the total reaching point to the multi-point system without the difficult incidence in the optical distribution network. Based on the results, the proposed amplifying passive optical network approach is capable of being used in passive optical networks in C band for extending the total reach of system or increasing the split ratio.

“…One of the most effective fronthaul access architectures that may offer high optical implementation capacity links and long-reach fiber is the Passive Optical Network (PON); the wavelength Division Multiplexing is one of the many modulations and multiplexing techniques employed by this network [5]. By using several wavelengths of fiber, WDM may support more users, hence increasing the capacity of the optical fiber network [6]. To enable future high bandwidth, residential and backup services, WDM-PON was developed in the late 1980s and is now suggested by many authors to be used as a solution that meets the required fronthaul link networks [7].…”

“…Using TWDM-PON is not preferable by the ITU-T in [11] because of the latency issue while WDM-PON shows superior performance with regard to latency and system capacity. An 8-channel with 2-10Gbps/λ WDM-PON 80 Gbps system with a single Erbium-Doped Fiber Amplifier (EDFA) has been reached by the researchers in [6]. The authors in [12] suggested and assessed a centralized light source WDM-PON architecture (CLS).…”

“…Moreover, utilizing this filter results in an upstream (US) optical interferometric noise reduction. The advantage of the proposed system in [6] is that it would increase the downstream capacity to 160 Gbps (16 channels at the rate of 10 Gbps) and 40Gbps (16 channels at the rate of 2.5 Gbps) for upstream transmission capacity. All the above works utilized NRZ and MZM as a bit coding and an optical modulation which use low-cost and simple systems to provide a solution for high bandwidth demand link applications.…”

This work designs an eighteen-channel bidirectional Intensity Modulation with Direct Detection (IM/DD) Wavelength Division Multiplexing-Passive Optical Network (WDM-PON) system. The proposed system meets the requirement of the ITU-T 5G fronthaul link suggested design in G-series Recommendations-Supplement 66. The newly designed system, with a 25Gb/s/λ data rate (450Gbps as a system capacity), has been tested and simulated using OptiSystem V.19 software. The system has been evaluated by the BER with respect to variable the optical span and CW laser power. Based on the ITU-T recommendations, the simulation results demonstrate that this system might be used as an F1 and as an Fx 5G fronthaul link for functional split choices starting from options 1 to 7a. These options are required under 25Gbps/λ for each upstream and downstream link direction. Furthermore, the proposed system utilized a bidirectional single-mode optical fiber within short optical spans of up to 10 km. The proposed system is characterized by a low-cost, simple, DSP-free and amplifier-free system with a reasonable system capacity.
