Abstract

In this paper, we present 50 GHz spaced 25 × 40 Gbit/s WDM transmission over 560 km using SMF-based Large Effective Area Fiber (LEAF) in a recirculating loop. The paper uses band-limited RZ signals carrying 2 31 -1 PRBS data, and shows that transmission distance of 560 km can be achieved with BER ≤ 10 -9 using 1 mW peak power and 4 ps pulse-width for each data signal. To attain this, optical filters with sharp transmission characteristics are used in both transmitter and receiver. The results demonstrated in this paper are based on simulation, and the author believes that the propagation distance reached in the paper is the longest distance achieved for such system

50ghz间隔25x40gbit /s WDM传输560公里基于smf的大有效面积光纤(LEAF)

在本文中，我们提出了使用基于smf的大有效面积光纤(LEAF)在循环环路中传输560公里以上的50 GHz间隔25 × 40 Gbit/s WDM传输。本文采用限带RZ信号携带2 31 -1 PRBS数据，表明在每个数据信号峰值功率为1 mW、脉宽为4 ps的情况下，在BER≤10 -9的情况下，可以实现560 km的传输距离。为了达到这一点，在发射器和接收器中都使用具有锐利传输特性的光学滤波器。本文所论证的结果是基于仿真的，笔者认为本文所达到的传播距离是该类系统所能达到的最远距离

期刊介绍： We would like to inform you, that iJOE, the ''International Journal of Online Engineering'' will accept now also papers in the field of Biomedical Engineering and e-Health''. iJOE will therefore be published from January 2019 as the ''International Journal of Online and Biomedical Engineering''. The objective of the journal is to publish and discuss fundamentals, applications and experiences in the fields of Online Engineering (remote engineering, virtual instrumentation and online simulations, etc) and Biomedical Engineering/e-Health. The use of cyber-physical systems, virtual and remote controlled devices and remote laboratories are the directions for advanced teleworking/e-working environments. In general, online engineering is a future trend in engineering and science. Due to the growing complexity of engineering tasks, more and more specialized and expensive equipment as well as software tools and simulators, shortage of highly qualified staff, and the demands of globalization and collaboration activities, it become essential to utilize cyber cloud technologies to maximize the use of engineering resources. Online engineering is the way to address these issues. Considering these, one focus of the International Journal of Online and Biomedical Engineering is to provide a platform to publish fundamentals, applications and experiences in the field of Online Engineering, for example: Remote Engineering Internet of Things Cyber-physical Systems Digital Twins Industry 4.0 Virtual Instrumentation. An important application field of online engineering tools and principles are Biomedical Engineering / e-Health. Topics we are interested to publish are: Automation Technology for Medical Applications Big Data in Medicine Biomedical Devices Biosensors Biosignal Processing Clinical Informatics Computational Neuroscience Computer-Aided Surgery.
