“…This achieved optical budget covers the losses of WDM MUX/DEMUX (2 × 4 dB), downstream/upstream separators (4 dB), and DLI (5 dB). An extra budget of 19 dB could be used for fiber transmission and an integration with the formers deployed PON systems, as a smooth mitigation of infrastructure is one of the major requirements from operators for WDM PONs [15]. This extra optical budget could also be used to employ power splitters to share time division multiplexed 10-Gbit/s bandwidth to a number of users.…”

This paper proposes the use of chirp-managed lasers (CML) as cost-effective downstream (DS) transmitters for next generation access networks. As the laser bandwidth is as high as 10 GHz, the CML could be directly modulated at 10 Gbit/s for downstream transmission in future wavelength division multiplexing passive optical networks (WDM PON). The laser adiabatic chirp, which is the main drawback limiting the transmission performance of directly modulated lasers, is now utilized to generate phase-shift keying (PSK) modulation format by direct modulation. At the user premise, the wavelength reuse technique based on reflective colorless upstream transmitter is applied. The optical network unit (ONU) reflects and orthogonally remodulates the received light with upstream data. A full-duplex transmission with symmetrical 10-Gbit/s bandwidth is demonstrated. Bit-error-rate measurement showed that optical power budgets of 29 dB at BER of 10(-9) or of 36 dB at BER of 10(-3) could be obtained with direct phase-shift-keying modulation of CML which proves that the proposed solution is a viable candidate for future WDM-PONs.

“…To achieve capillary network coverage, 5G‐Crosshaul is designed with a mix of technologies to implement a unified backhaul and fronthaul infrastructure encompassing multiple media such as optical fibre, mmWave and copper wires. Among state‐of‐the‐art systems and standards, Dense Wavelength Division Multiplexing (including NGPON2 ) and wireless (including mmWave ) are technologies that can potentially meet the 5G‐Crosshaul requirements in terms of number of users, user capacity, link distance, energy efficiency latency, cost, and scalability. However, these technologies cannot be used as they currently are but need to be adapted to the new application area.…”

This paper presents the control and data plane architecture design for a 5G transport solution (5G-Crosshaul) with the aim of integrating the fronthaul and backhaul network segments in a common transport stratum. The control plane relies on the Software-defined networking/Network Functions Virtualization concept to control and orchestrate the different elements of the network (the 5G-Crosshaul control infrastructure). The data plane is based on an mixed optical/packetbased forwarding entity (the 5G-Crosshaul forwarding element) that leverages the benefits of optical passthrough with the statistical multiplexing of packet-based transmission, working on top of a common frame format for both, fronthaul, and backhaul traffic (the 5G-Crosshaul common frame). In addition to the main architecture design, this work includes the impact of providing multi-tenancy support into the architecture of the overall system, in order to share the costs of building and operating the infrastructure among different operators.This architecture opens the 5G transport network as a service for innovative network applications on top (such as multitenancy, and resource management ), provisioning the required network and IT resources in a flexible, cost-effective, and abstract manner. The proposed design supports the concept of network slicing pushed by the industry for realizing a truly flexible, sharable, and cost-effective future 5G system.

“…Passive optical network (PON), which is of high capacity and long reach, is candidate technology to solve the bandwidth problem. Studies about the evolution of 10Gigabit-PON, known as NG-PON2, have already started at the FSAN with a focus on 1) increasing the aggregate bit-rate to at least 40Gb/s at the central office interface; 2) consolidating the number of central offices and increasing the amount of eligible users through extended optical budgets and 3) preserving operability with former deployed generations and services while maintaining costeffective solutions at the user side [1]. The structure of upstream is still a challenge for next generation optical access networks.…”
