Firstly  the development of optical module and the characteristics of QSFP+ module are illustrated   The design of high-speed optical fiber communication system based on PCI bus (EI CONFERENCE) 会议论文  OAI收割 2010 2nd IEEE International Conference on Advanced Management Science, ICAMS 2010, July 9, 2010 - July 11, 2010, Chengdu, China 作者:  Zhang L.-G.;  Zhang L.-G.;  He X. 收藏  |  浏览/下载：57/0  |  提交时间：2013/03/25 In order to increase the transmission distance and reduce noise effectively  a communication system with the optical fiber interface is developed in this paper. In the system  the PCI bus is adopted as the connection bus between the underlying optical fiber transceiver module circuitry and host computer using the WDM driver. The FPGA is the core logic of the whole system  responsible for data transmission and timing logic control. The module structure and the design method of the PCI bus  the principle and the design of optical interface module and the bottom-driven development are described in this paper. The experiment results show that the system has basically meet requirement targets. It can achieve the maximum transfer rate of 40MBps when running in the DMA mode. With long transmission distance  strong antiinterference and high scalability  this system has stable and reliable performance. 2010 IEEE.   Integrated optical amplifiers based on rare-earth doped (red) oxide glasses (EI CONFERENCE) 会议论文  OAI收割 International Symposium on Photonic Glass (ISPG 2002), October 14, 2002 - October 17, 2002, Shanghai, China 作者:  Chen B.;  Chen B. 收藏  |  浏览/下载：38/0  |  提交时间：2013/03/25 Oxide glasses have been used since long time to host a number of active compounds  first of all rare-earth (RE) ions  for lasing. Recently  the advantages offered by guided-wave format  namely the small size  the high pump power density  and the larger flexibility in design and fabrication  led to the development of fiber lasers and amplifiers based on Er3+-doped glasses. Currently  a growing activity is aimed at achieving large optical gain in Er3+-doped planar waveguides  having in mind the single-chip realization of integrated optical amplifiers and lasers. The aim of the present paper is to provide a quick overview of this area and to briefly discuss possible future developments.
