Abstract

The optical access network is currently driving studies on transmissions beyond 10 Gbit/s. This paper reports an analysis of Pulse Amplitude Modulation (PAM), seen as a promising candidate for future Passive Optical Networks (PON). Previous 25 Gbit/s real-time PAM4 results are extrapolated here with simulations to higher bit rates and a higher number of PAM levels. Our main goal is to evaluate the compliancy of PAM with the existing standards and legacy networks as far as fiber length, optical budget class, and wavelength plan are concerned. The simulations enlighten us as to the challenges of multilevel modulation formats, such as noise and jitter, compared to the currently adopted Non-Return-to-Zero (NRZ).

Abstract

Intensity-Modulation-Direct-Detection (IM/DD) is currently applied for Higher Speed Passive Optical Networks (HS-PONs), which are undergoing standardization by ITU-T [1] . The main constraints are Chromatic Dispersion (CD), which induces dips in the amplitude of the channel frequency response, and chirp, which adds a parasitic angle modulation term to the signal. The combined effect of CD and chirp impacts the position and depths of the fading dips, limiting channel capacity even more [2] , [3] . Digital equalization at receiver have been proposed as solutions to increase propagation distance. Nevertheless, at 50Gbit/s the channel penalties are higher and techniques to compensate the impairments have to be investigated.

Abstract

International audience; In this paper, the challenges of next generation passive optical networks are identified, and a promising solution to mitigate them is proposed using a unified/fixed weights of channel equalization. Possible layouts of existing and future networks employ different values of data rate, wavelength range, laser chirp, and fiber length. Therefore, adaptive equalizer weights are used in order to compensate the effects of those requirements, but at the cost of increased complexity and time constraints. The originality of this paper is in utilizing a single impulse response of the equalizer through fixed weights to satisfy any network configuration and to highly simplify signal processing operations. The simulated and experimental results are in very good agreement in which bit-error-rate of 10(-2) is obtained at -27 dBm received optical power using 20 km fiber length.

Abstract

Software Defined Networking (SDN) has come up as a promising technology for making the communication networks more flexible and dynamically (re)configurable. With the advent of fifth generation (5G) of mobile networks, the aforementioned flexibility became more urgent and critical than ever. SDN offers the decoupling of the network’s control plane from the data plane. As a result, the infrastructure layer can be abstracted from the application and network services and therefore the network control can be done completely through a centralized component/orchestrator. In this work, a detailed practical deployment of an SDN controller for a converged FiberWireless (Fi-Wi) 5G network is presented, followed by the SDN architecture and functional components. Lastly, an experimental trial using an SDN controller directly connected to Fi-Wi lab equipment is described, in which the physical layer parameters are managed and monitored successfully, proving the applicability of SDN in a Fi-Wi network.

Abstract

5G networks are shaping a new ecosystem necessitating various transformations of the existing network infrastructures combined with the use of network softwarization and programmability, so as to satisfy the needs of all the involved stakeholders (telecom/service providers, infrastructure owners, tenants, vertical industries, end-users, etc.), while a wide range of issues have to be addressed spanning from technology to business domains. The 5G-PPP project 5G-PHOS [1] proposes a novel framework to allow telecom operators and service providers to overcome 5G densification issues while supporting the stringent 5G requirements in a flexible and cost efficient manner to allow for commercialization. This paper aims at providing indicative architectural instantiations of the 5G-PHOS solution, depicting the way the technology supports the 5G requirements and the stakeholders’ needs along with the functionalities and the deployment feasibility of an ambitious 5G fronthaul/backhaul network solution.

Abstract

This invited paper proposes to discuss the optical network synergies between the two main access technologies today: mobile, with the coming 5G, and fixed broadband, which is migrating to full Fiber To the Home (FTTH). 5G aims to offer a fiber-like user experience, providing low latencies and high throughputs. Such requirements impose not only that optical fiber reaches the antenna site (in Fiber To The Antenna topologies, FTTA) but also that optical fibers are used to connect Radio Access Network (RAN) equipment at the antenna site (between Radio Units (RUs) and the cabinet hosting Digital Units (DUs)). At the same time, thanks to FTTH, optical fibers are increasingly more available in the ducts and cabinets for the massive broadband residential deployment. Current central offices are equipped with Optical Line Terminals (OLTs) shelfs which support Gigabit capable Passive Optical Network (G-PON) and Gigabit Point to Point (PtP). 10 Gigabit symmetrical PON (XGS-PON) and PtP are the coming deployable solution for an enhanced fixed broadband. We propose in this paper to investigate the synergies between optical fiber networks (both FTTA for 5G and FTTH), keeping in mind that the number of antennas is still very low compared to the number of fixed access premises.

Abstract

In this paper it is analysed the impacts of the non-linearity of a fast fluorescent optical source at 560 nm in terms of signal to noise ratio degradation in discrete multitone transmissions. The optical source has been developed at our laboratory to increase the aggregate data bit rate in wavelength division multiplexing systems over plastic optical fibre. The results have shown that even operating outside the linear region of the optical source, it is possible to increase the multi-carrier signal to noise ratio, which leads to a spectral efficiency improvement.

The optical access network is currently driving studies on transmissions beyond 10 Gbit/s. This paper reports an analysis of Pulse Amplitude Modulation (PAM), seen as a promising candidate for future Passive Optical Networks (PON). Previous 25 Gbit/s real-time PAM4 results are extrapolated here with simulations to higher bit rates and a higher number of PAM levels. Our main goal is to evaluate the compliancy of PAM with the existing standards and legacy networks as far as fiber length, optical budget class, and wavelength plan are concerned. The simulations enlighten us as to the challenges of multilevel modulation formats, such as noise and jitter, compared to the currently adopted Non-Return-to-Zero (NRZ).
