Real-Time Rogue ONU Identification with 1D-CNN-Based Optical Spectrum Analysis for Secure PON

Optical Fiber Communications Conference and Exhibition, 2019
We proposed a real-time optical spectrum analysis method with one-dimensional convolutional neural network to identify rogue ONUs in PON. Experimental results show that 100% rogue ONU identification accuracy is achieved within 12.6 milliseconds on ...

Demonstration of ONU Activation for In-Service TDM-PON Allowing Uninterrupted Low-Latency Transport Links

Optical Fiber Communications Conference and Exhibition, 2019
We propose an upstream-traffic-disruption-free ONU activation method enabling low-latency services over TDM-PON. We demonstrate ranging using only 5-μs-long empty window independent from fiber length, a significant improvement over 250/450-μs quiet ...

FTTdp: ONU Complexity Reduction

Optical Fiber Communication Conference, 2014
We define and evaluate two strategies for reducing the complexity of an optical network unit deployed in a hybrid PON/DSL access network. This complexity reduction will result in reduced energy consumption and cost.

Reporting in ONUs with reduced buffers

2012 16th International Conference on Optical Network Design and Modelling (ONDM), 2012
In this work, we consider a passive optical network (PON) with reduced buffer capacity at the Optical Network Unit (ONU). The objective is to reduce the ONU power consumption by having smaller buffers. This requires that some of the end-nodes packets be buffered at the end-node itself (EN) and some buffered at the ONU.

The Onus for Altruism in Kidney Transplantation

European Urology Focus, 2018
Ideally, all programs performing living donor kidney transplantation should educate patients on all contemporary exchange options. They should be strongly encouraged to participate in multicenter exchange, or at least refer those with a willing yet incompatible donor to a center that does, and to preferentially allocate altruistic donor kidneys towards

DBA Algorithm with Prioritized Services for 10G-EPON with Multi-ONU Customers

IEEE Latin-American Conference on Communications, 2019
Passive optical networks (PONs) provide high access capacity to multiple services and applications. However, the deployment of PONs involves significant costs. On the other hand, infrastructure provider (InP) can lease their PONs to several customers. In

Dynamic Bandwidth Allocation with Multi-ONU Customer Support for Ethernet Passive Optical Networks

International Symposium on Computers and Communications, 2018
This paper introduces a mechanism for the support of multi-ONU service level agreements (SLAs) in dynamic bandwidth allocation (DBA) algorithms for Ethernet passive optical networks (EPON). The employment of SLAs for multiple optical network units (ONUs)

ONUS

This part explores the concept of tabanca—a form of longing—with specific attention to its potential as an emancipatory device. Consisting of three historiographic essays—“Onus,” “Conscientia,” and “Textus”—the series extends the interpretation of the term with ekphrastic analyses of three artworks designed by the author.

GPON Network with Simulated Rogue ONU

International Conference on Software, Telecommunications and Computer Networks, 2019
This work addresses security risks in a gigabit passive optical network. The completely passive infrastructure enables active monitoring of the distribution network in parallel with data communication.

Schemes of optical power splitter nodes for direct ONU–ONU intercommunication

Microwave and Optical Technology Letters, 2009
AbstractIn this study, two schemes of optical power splitter nodes to enable direct local intercommunications between optical network units (ONUs) in a passive optical network (PON) are proposed and analyzed. In comparison with the existing schemes, the new schemes dramatically increase the number of ONUs supported in a PON with the capability of ...
