20-Gbps optical LiFi Transport System.
Optics letters, 2015Co-Authors: Cheng-ling Ying, Chun-jen Cheng, H H Lu, Chung-yi Li, Peng-chun Peng, Wen-jeng HoAbstract:A 20-Gbps optical light-based WiFi (LiFi) Transport System employing vertical-cavity surface-emitting laser (VCSEL) and external light injection technique with 16-quadrature amplitude modulation (QAM)-orthogonal frequency-division multiplexing (OFDM) modulating signal is proposed. Good bit error rate (BER) performance and clear constellation map are achieved in our proposed optical LiFi Transport Systems. An optical LiFi Transport System, delivering 16-QAM-OFDM signal over a 6-m free-space link, with a data rate of 20 Gbps, is successfully demonstrated. Such a 20-Gbps optical LiFi Transport System provides the advantage of a free-space communication link for high data rates, which can accelerate the visible laser light communication (VLLC) deployment.

optical free space wavelength division multiplexing Transport System
Optics Letters, 2014Co-Authors: Chunyu Lin, Yingpyng Lin, Chiayi Chen, Taiwei Jhang, Minchou ChenAbstract:An optical free-space wavelength-division-multiplexing (WDM) Transport System employing vertical cavity surface emitting lasers and spatial light modulators with 16-quadrature amplitude modulation orthogonal frequency-division multiplexing modulating signals over a 17.5 m free-space link is proposed and demonstrated. With the help of a low-noise amplifier and data comparator, good bit error rate performance is obtained for each optical channel. Such an optical free-space WDM Transport System would be attractive for providing services including data and telecommunication services.

High available System control network in the packet Transport System
Digest of the 9th International Conference on Optical Internet (COIN 2010), 2010Co-Authors: Bup-joong Kim, Woo-young Choi, Ji-wook Youn, Hong-ju Kim, Hyun Jae LeeAbstract:This paper is about design and buildup of multiprocessor interconnects in the packet Transport System. To keep pace with expansion and growth of internet and data communication, constant enhancement and upgrade of packet Transport System is required. As network adopts new services like IPTV, VoIP, and VLAN, processing power of packet Transport System should be easily and dynamically added to the System for supporting highly compute-power requiring jobs. The processing power of System depends on the number of processors, the clock speed of each processor, efficiency of operation System in data centric processing, proper distribution of System works, and robust and high bandwidth interconnects (System control network) among processors. This paper suggested several methods for the System control networking in the packet Transport System and reviewed each method in the view of internal and external expansion of System control network, loop elimination, and redundancy support.

Demonstration of packet-optic integrated Transport System
Digest of the 9th International Conference on Optical Internet (COIN 2010), 2010Co-Authors: Ji-wook Youn, Bup-joong Kim, Woo-young Choi, Hyun Jae Lee, Hong-ju KimAbstract:We propose and experimentally demonstrate a packet optical integrated Transport System. The proposed System supports packet Transport layer features based on PBB-TE. The restoration time from a link failure is measured to be about 20 ms and 11.8 ms, respectively, in the packet Transport layer and optical Transport layer. The measured restoration time is much smaller than the 50 ms industry requirement for real-time services. The fast restoration time allows the proposed packet-optic integrated Transport System to offer high availability and reliability which is a requirement for Transport networks.

Systems and actors: the Transport System
J. of Design Research, 2010Co-Authors: Bert Van WeeAbstract:Transport Systems develop due to the interactions between actors and the technical options for Systems. This interaction is of major importance for the design of Transport infrastructures. This paper gives an overview of the links between the Systems and the actors in the Transport System. It describes some dominant features of the Transport System, elaborates on the difference in the goals of the public and private actors, and gives an overview of dominant theories and research methods. As an illustration we present the case of the Zuiderzee line, a new railway line that may be built between the highly urbanised western part of The Netherlands and the North of the country.
