“…The receiver sensitivity has been defined as the minimum received power with a maximum BER of 10 -3 , which is the maximum allowed BER by the forward error correction (FEC) as stated on the NG-PON2 standard [4]. Fig.…”

“…The dispersion penalty has been subtracted from the power budget in order to show just the allowed optical path losses. In the power budget calculation, the fiber attenuation is considered as 0.25 dB/km and the splitter losses are considered as 3.5 log2(M) dB with M being the splitting ratio [4]. We will discuss the obtainable power budget using the tested EML as the transmitter but also using typical NG-PON2 transmitters, which provide higher optical powers.…”

“…In order to address the current and future data traffic requirements, the NG-PON2 standard for passive optical networks (PON) was recently released [3,4]. The NG-PON2 standard is based on time and wavelength division multiplexing (TWDM) through four wavelength channels at a data rate of 10 Gbps per channel and providing an aggregated data rate of 40 Gbps.…”

In this paper, we propose and test experimentally a real-time 10 Gbps polarization independent quasicoherent receiver for NG-PON2 access networks. The proposed 10 Gbps quasicoherent receiver exhibits a sensitivity of-35.2 dBm after 40 km SSMF transmission with a commercial generic EML as transmitter. This sensitivity means a 14.9 dB improvement over a direct detection scheme with a photodiode after 40 km SSMF transmission. Therefore, the use of the proposed 10 Gbps quasicoherent receiver with the tested EML will provide a power budget of 35.64 dB (class E2) and a splitting ratio of 128 after the 40 km SSMF transmission. Finally, the proposed 10 Gbps quasicoherent receiver allows a colorless and optical filterless operation because wavelength selection is done by tuning the local oscillator wavelength and using electrical intermediate frequency filtering.

“…Major requirements for the structural convergence are thus the ability to provide bit rates of ≥ 10 Gb/s (at least to dedicated business customers and remote radio heads, RRH) and to fulfill strict latency/jitter requirements, which are mandatory for mobile fronthaul connections. A good candidate for such a unified network infrastructure is a WDM-PON (wavelengthdivision multiplexed passive optical network) as currently being specified by the FSAN and ITU-T Study Group 15, Question 2 (ITU-T G.989.2) [5] [6]. Another central element in the FMC concept is a next generation point-of-presence (NG-POP) which provides a Universal Access Gateway (UAG).…”

Fixed-Mobile Convergence (FMC) is a very trendy concept as it promises integration of the previously separated fixed access network and the mobile network. From this novel approach telecommunication operators expect significant cost savings and performance improvements. FMC can be separated into structural convergence (regarding the infrastructure) and functional convergence (regarding the necessary functionalities required in fixed and mobile networks). The latter one goes hand-in-hand with Network Function Virtualization (NFV), where important network functions are provided by a server inside of the next generation point-of-presence (NG-POP). In this article implications on the system architecture as well as structural and functional convergence topics will be discussed.

“…Current PON FTTx technologies such as 10 Gigabit-PON, 10 G Ethernet-PON utilise time-division multiplexing (TDM), and the recently announced next generation PON technology (NG-PON2), offering at least 40 Gb/s (4 λ × 10 Gb/s) aggregate network capacity 2–5 , will employ time-wavelength division multiplexing 6, 7 coupled with direct detection receivers. However, TDM transceivers used in ONUs operate at aggregate data rates rather than the data rate per subscriber.…”

High-speed broadband services require optical fibres in access networks, in which multiple subscribers are connected to service providers, to satisfy the continuously growing bandwidth demand. The primitive signaling scheme used in access networks enables the use of low-cost equipment but diminishes the bandwidth available to end-users. Thus, current technology will be unable to support future broadband demands. Coherent communication systems offer significantly improved power- and bandwidth-efficiency, but require fundamental simplifications to become economically viable for access networks. Here, we demonstrate a promising simplified coherent receiver exhibiting a robust performance against polarisation fluctuations over an installed fibre network. It enables the realisation of high-order modulation formats and offers high sensitivities, achieving a four-fold increase in the supported number of subscribers and approximately doubling the transmission distance compared to the recently standardized access technology. The proposed solution indicates that digital coherent technology can be feasible and transform the access networks, enabling ubiquitous new services and applications with uncontended, multi-gigabits/user broadband connections.
