Poster: SDN based energy management system for optical access network

Abstract: In recent years, Passive Optical Network (PON) is developing rapidly in the access network, in which the high energy consumption problem is attracting more and more attention. In the paper, SDN (Software Defined Network) is first introduced in optical access networks to implement an energy-efficient control mechanism through OpenFlow protocol. Some theoretical analysis work for the energy consumption of this architecture has been conducted. Numeric results show that the proposed SDN based control architecture can reduce the energy consumption of the access network, and facilitates integration of access and metro networks.

Passive optical network employing multi-carrier code division multiple access

Abstract: A passive optical network (PON) for providing a large amount of data at high speed to subscribers is provided. In particular, a PON employing a multi-carrier CDMA in which a CDMA method is applied for an upstream signal is provided. The PON employing a multi-carrier CDMA includes: optical network terminals (ONTs) for transmitting CDMA-based data using multiple carriers to an optical line terminal (OLT) and for receiving Ethernet-based data transmitted from the OLT; the OLT for transforming CDMA-based data received from the ONT into Ethernet-based data, for transmitting the Ethernet-based data to a higher network, and for transmitting Ethernet-based date to the ONTs; and an optical coupler for coupling CDMA-based optical signals transmitted from the ONTs, for transmitting the coupled optical signal to the OLT, and for distributing an Ethernet-based optical signal transmitted from the OLT to the ONTs.

Evolution of burst mode receivers

Abstract: The paper gives an overview of burst-mode receiver developments. The receiver design challenges associated with high speed TDMA PONs are discussed and recent results of 10Gb/s burst-mode receivers are highlighted.

Technologies and architectures to enable SDN in converged 5G/optical access networks

Abstract: The challenging performance targets of future 5G networks will require a radical change in the network design with a much closer interaction between wireless and optical systems. Dynamically reconfigurable time-division multiplexing (TDM) dense wavelength division multiplexing (DWDM) long-reach passive optical networks (PONs) provide a promising platform to enable the convergence of residential broadband, enterprise connectivity and wireless data traffic onto a single network architecture by exploiting the dynamic allocation of DWDM channels. In this paper we describe the architectural choices and the specific technologies that are required by these designs. We also demonstrate the co-existence of heterogeneous services and modulation formats, i.e. residential 10G PON channels, business 100G dedicated channel and wireless fronthaul on long reach TDM-DWDM PON systems. Two different TDM-DWDM PON designs are demonstrated: the first one for densely populated urban areas; and the second one better suited for rural deployment. Two service use cases are also demonstrated by implementing end-to-end software defined networking (SDN) management of the access and core network elements: a fast protection mechanism with end-to-end service restoration in the case of a primary link failure; and dynamic wavelength allocation (DWA) in response to an increased traffic demand.
