“…For co-existence of PON technologies, challenges related to OOB, SRS, spectral specifications and interoperability were identified. Extension of PON market towards fibre to everywhere (Fiber To The Room, Machine, Industry…) in the future [6] will also raise other co-existence questions, maybe more related to management and orchestration interfaces, when cascading multiple PtP/PONs is considered [14].…”

“…3b uses a single PON for all protection links with 10G-EPON technology. Here, the programmable NETCONF/Yang switch [13] together with the intelligent SFP+/PON plays the role of the OLT in the central office (CO) [17]. SFP+/ONUs are chosen for PON protection solution since such a small and flexible module can be inserted directly into the pre-existing switch near the antenna site.…”

In this paper, we propose a Software Defined Network-based (SDN) Passive Optical Network (PON) Radio Access Networks (RAN) protection scheme. We experimentally assess the performance by implementing it through a testbed including an SDN controller, Small form-factor pluggable transceiver PON (SFP+/PON), a layer 2 switch, and several SFP+ Point-to-Point (SFP+/PtP) in lieu of a traditional OLT chassis. We compared our proposition with a PtP scheme based on legacy layer 2 redundancy protocol solution with respect to different metrics such as recovery time, latency, power consumption, CAPEX and flexibility/scalability. We show that a trade-off exists among those metrics and that while the SDN-based solution is outperformed by the legacy-based one in terms of recovery time, the proposed solution still provides a remarkable improvement with respect to nowadays practices in protection, while allowing for cost and energy reduction. Such solution scheme can thus be used as a protection scheme for non-time-critical services.

“…Meanwhile, a passive optical network (PON) system is a connection between the central office and the end user's home, office and factory through the optical fiber. The use of PONs [5] and passive optical local area network (POLAN) [6] for broadband services have been presented currently. Many broadband providers are already being used these technologies to offer broadband services for consumers.…”

Explosive growth and usage of internet while COVID-19 pandemic demands an access technology in our lifestyle that means the Internet of Things (IoT) and Passive Optical Networks (PONs) are increasingly being used in order to support the digital lifestyle. Mobile Internet allows us firstly to exchange the content of information and multimedia while on the move. Then, IoT makes it possible to connect the smart devices with the low latency. PONs have been suggested for providing the ultra-low latency for Quality of Service (QoS) applications such as the Tactile Internet (TI) that is the next evolution to enable real-time control of IoT. A one-millisecond round-trip delay is required to support the tactile internet. As stated on the improving bandwidth allocation for PONs and Passive Optical LAN (POLAN), we propose the FiWi-Dynamic Wavelength and Bandwidth Allocation (F-DWBA) algorithm to reduce the round-trip delay at lower than one-millisecond, which the proposed F-DWBA algorithm based on the PONs and WLAN 802.11b should have a maximum performance. The lowest round-trip delay will make the Fiber-Wireless (FiWi) system can work efficiently and support TI applications. Simulation setup are tested on the latency budget of communication for the TI system starting from the Mobile Unit (MU) through the access point (AP) connected to the Optical Network Unit (ONU) including with the Optical Line Terminal (OLT) to the server. Performance analysis is focused on three periods of the latency time at the optical access network, radio interface and MU interface. Simulation results show that the proposed F-DWBA algorithm has a better round-trip delay than the Gigabit-Passive Optical Network (G-PON) standard about 40 percentage and better than the conventional Dynamic Wavelength and Bandwidth Allocation (DWBA) algorithm about 33 percentage at the full working of the tactile internet system.
