TL;DR: Possible configurations of tunable components for the next-generation passive optical network stage 2 (NG-PON2) are reviewed on the basis of system requirements and the concept of in-service tuning in colorless ONUs is reviewed.
Abstract: Possible configurations of tunable components for the next-generation passive optical network stage 2 (NG-PON2) are reviewed on the basis of system requirements. Expected network functions in NG-PON2 systems along with the concept of in-service tuning in colorless ONUs are also reviewed.

TL;DR: Simulation results indicate that the proposed OCDMA-PON scheme is feasible and that the novel design can improve the scalability and transmission performance of the optical access networks.
Abstract: In this paper, a novel Passive Optical Network based on Optical Code Division Multiple Access (OCDMA-PON) is presented. The design of the Optical Line Terminator (OLT) and the Optical Network Unit (ONU) for the OCDMA-PON are studied in detail. The proposed OCDMA-PON combines the advantages of PON and OCDMA technology and it can be applied to an optical access network with full services on demand, such as internet protocol, video on demand, tele-presence and high quality audio. Compared to other multiple access technologies, the proposed OCDMA-PON provides more ONU and assembly flexibly for PON. We analyze in detail the scalability and system transmission performance of such a network. Simulation results indicate that the proposed scheme is feasible and that the novel design can improve the scalability and transmission performance of the optical access networks.

TL;DR: Current advances in photonic technologies and architectures enable the optical layer to become the ideal companion of the packet world and to unlock an effective packet offload toward flexible and dynamic optical pipes.
Abstract: The telecommunication community has reached a broad consensus on the vision that future transport architecture will be dominated by optical in combination with IP. This implies a complete reassignment of the functions traditionally handled by legacy intermediate layers to packet and optical layers only. Here, current advances in photonic technologies and architectures enable the optical layer to become the ideal companion of the packet world and to unlock an effective packet offload toward flexible and dynamic optical pipes. A global crosslayer optimization is needed to minimize the misalignment between cost and revenues, and manage the rising tide of IP traffic. In this article, we describe this evolving path and explore the impact on network planning and traffic provisioning, also considering implications on the cloud scenario and sighting the software defined networks horizon.

TL;DR: A novel algorithm to evaluate the time division multiple access (TDMA) protocol which controls the traffic from the various subscribers towards the shared access equipment (upstream direction) is proposed and it uses counters to estimate the moment of a data packet arrival at the subscriber side.
Abstract: For shared access to a broadband communication network using the asynchronous transfer mode (ATM) a passive optical network (PON) has previously been proposed. A novel algorithm to evaluate the time division multiple access (TDMA) protocol which controls the traffic from the various subscribers towards the shared access equipment (upstream direction) is proposed. It uses counters to estimate the moment of a data packet arrival at the subscriber side. By this ‘look-ahead’ technique no extra upstream channels are needed to initiate the polling by the subscriber. The algorithm guarantees fair access for all subscribers and minimizes the necessary overhead. Both the maximum access delay and overhead may be readily calculated, and the obtained results were supported by numerical simulation. Applicability in the standard broadband network environment has been proved by hardware design simulation.

TL;DR: A novel TDM (time-division multiplexing) sampling technique for demultiplexing and selecting digital video channels at the customer end is described, and a 323-channel capability has been demonstrated at 2.2 Gb/s over an experimental optical network.
Abstract: A passive optical local access network for telephony applications is proposed which can evolve a future broadband ISDN (integrated services digital network). A laboratory demonstrator has been constructed which can deliver a 144-kb/s ISDN channel, or the equivalent to 128 customers from a single fiber exchange. Options for evolution to broadband ISDN are discussed with emphasis on choice of multiplexing technique. A novel TDM (time-division multiplexing) sampling technique for demultiplexing and selecting digital video channels at the customer end is described. A 323-channel capability has been demonstrated at 2.2 Gb/s over an experimental optical network. >
