Abstract

The growing multimedia, bandwidth-hungry applications, and real-time services drive tremendous expansion in the communication industry and force service providers to look for more effective ways to provide reliable, energy-efficient, cost-efficient, high-speed, and low-latency data transmission. In this paper, the authors proposed a new energy-efficient and flexible architecture such as a Time and Wavelength Division Multiplexed Passive Optical Network (TWDM-PON) that can enable an Optical Line Terminal (OLT) network sharing of available resources. The proposed architecture can broadcast and/or transmit Point-to-Point (P2P) data for downstream (DS) transmission. The architecture offers low latency direct and dedicated Optical Network Unit (ONU) connections and exhibits the inter-ONU transmission that permits data exchange between two ONUs housed within an Optical Distribution Network (intra-ODN-inter-ONU). The proposed architecture can also send the inter-ONU signals between the ONUs located over different ODNs (inter-ODN-inter-ONU) in the same Optical Private Network (OPN). By implementing the intra-ODN-inter-ONU and inter-ODN-inter-ONU transmissions, the proposed architecture can enhance security and reduce the transmission latency significantly. To the extent of the author’s information, dedicated inter-ODN-inter-ONU transmission has not been addressed in any of the literature till date.

The proposed architecture also supports, dedicated inter-ODN broadcasting within an OPN for transmitting the same data among multiple ONUs and utilizing the OLT resources optimally. Due to the dynamic recourse allocation at OLT, the proposed architecture provides up to 3-X service reliability and can operate on as minimum as one-third of network resources during low traffic load conditions. Furthermore, through the simulation of the proposed architecture, the Bit Error Rate (BER) performance is in the range of 10^-9 to 10^-12, under various inter-ONU connections. The proposed architecture also reduces upto maximum of 75% of the energy consumption. The proposed architecture would be suitable for enabling a variety of high-speed, real-time internet-based applications for mixed-use building customers and smart communities.

支持Inter/Intra-ODN的TWDM PON架构，实现不同光网络间OLT资源的高效共享

不断增长的多媒体、高带宽应用程序和实时服务推动了通信行业的巨大扩展，并迫使服务提供商寻找更有效的方法来提供可靠、节能、经济、高速和低延迟的数据传输。本文提出了一种节能、灵活的新型时波分复用无源光网络（TWDM-PON）架构，使光线路终端（OLT）网络能够共享可用资源。提出的体系结构可以广播和/或传输点对点（P2P）数据以供下游（DS）传输。该架构提供低延迟直接和专用的光网络单元（ONU）连接，并展示了ONU间传输，允许位于光分配网络（internal - odn -inter-ONU）内的两个ONU之间进行数据交换。该架构还可以在同一光私网（OPN）中位于不同odn上的onu之间发送onu间信号（inter-ODN-inter-ONU）。通过实现onu内部odn - onu之间和onu之间odn - onu之间的传输，该架构可以显著提高安全性并降低传输延迟。就作者所知，迄今为止，在任何文献中都没有涉及odn - onu之间的专用传输。该架构还支持OPN内专用的跨odn广播，以便在多个onu之间传输相同的数据，并最佳地利用OLT资源。由于OLT的动态资源分配，所提出的架构提供了高达3-X的业务可靠性，并且在低流量负载条件下可以运行至少三分之一的网络资源。此外，通过对所提架构的仿真，在不同的onu间连接下，误码率（BER）性能在10-9到10-12之间。提出的架构还减少了高达75%的能源消耗。拟议的架构将适合为混合用途建筑客户和智能社区提供各种高速、实时的基于互联网的应用。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
