“…Figure 5 shows a proposed migration path from the current AON PtP to WDM-PON. The considered WDM-PON implementation [9][20] has 80 wavelength channels with space of 50 GHz, which is beyond the standardized WDM-PON option in NG-PON2 [8]. Cyclic Arrayed Waveguide Gratings (AWGs) are used at the CO to aggregate 80 distribution fibers into one feeder fiber which uplinks to the OLT at the MAN.…”

“…TWDM is a hybrid technology of WDM and TDM, which is also used by ITU-T [6] as a primary technology for NG-PON2. In this paper, the considered TWDM-PON implementation [9][20] has 40 wavelength channels, which is beyond the 4 or 8 wavelength channels defined in the current NG-PON2 standard [8]. In the considered migration case, the active RNs are replaced by passive power splitters (1:32), while the Ethernet switches at the old COs are replaced by 40-channel AWGs (see Fig.…”

Abstract-Active Optical Network (AON) has been one of the most deployed fiber access solutions in Europe.However, with the increasing traffic demand, the capacity of the existing AONs is becoming insufficient. For the legacy AONs, there are two major variants of architectures, namely point-to-point and active star.Considering the different characteristics of these two AON architectures, this paper proposes and analyzes several migration paths towards Next Generation Optical Access (NGOA) networks offering a minimum 300Mbit/s sustainable bit rate and 1Gbit/s peak bit rate to every end-customer. Furthermore, this paper provides detailed descriptions of the network cost modeling and the processes for AON migration. The Total Cost of Ownership (TCO) for the proposed migration paths are evaluated taking into account different migration starting times, customer penetration, node consolidation and business roles in the fiber access networks. The migration from AON to NGOA can be economically feasible. The results indicate that a network provider plays a key business role and is responsible for the major part of TCO for AON migration.Moreover, performing node consolidation during AON migration can be beneficial from the cost point of view, especially in rural areas.

Double‐RSOA colorless WDM‐PON for 5G fronthaul applications

The introduction of 5G mobile systems poses significant challenges to the design of the fronthaul structure. The dense coverage, comprising several small cells operating in the millimeter‐wave range, with an enormous number of antennas, makes conventional digital‐radio‐over‐fiber unfeasible. On the other hand, the centralized architecture of the optical fronthaul is well‐suited for the passive optical network (PON) topology, with WDM‐PON as a strong contender due to its capability to establish logical point‐to‐point optical links to each cell site. However, the large‐scale deployment of WDM‐PON requires the availability of colorless transmitters, where the same hardware is able to generate any wavelength needed by the network. In this context, this paper investigates an analog fronthaul configuration over a colorless WDM‐PON for 5G and beyond, employing the techniques of self‐seeding in the downlink and carrier reuse in the uplink. We numerically evaluated the EVM when transmitting 1.25 Gbps at 3.5 GHz and 10 Gbps at 26 GHz in a 20 km optical link. The results are within the 3GPP requirements, demonstrating the feasibility of the proposed fronthaul.
