【摘要】：随着高速数据业务的迅速发展,人们对带宽的要求越来越高。现今使用最广泛的10Gbps以太网技术已渐渐表现出局限性,40Gbps传输业务成为业界关注的焦点。将波分复用(WDM)技术运用到40Gbps传输业务中,一方面能极大地提高光纤传输系统的容量和光纤利用率,另一方面,能充分利用光纤具有的巨大潜在带宽。因而在40Gbps以太网技术中,利用波分复用技术,可迅速为网络提供更大容量、更高速率的新业务,使光纤通信具有更广阔的发展前景。如今数据中心的功能越来越强大,处理的数据容量越来越大,10G以太网传输已经无法满足人们的需求,更高速率以太网传输技术的出现迫在眉睫,以支持服务器以更高的速率传输更多的数据。但在超出100m的范围发送100G是十分困难的,开发时间远远长于预期,因而40G以太网传输技术作为10G和100G以太网技术的过渡而被提上日程。与40G以太网传输技术匹配的40Gbps光模块,也得到运用,其能向下兼容10Gbps光模块速率的业务传输,也能为将来的100Gbps光模块服务。因此40Gbps光模块具有广阔的市场前景。本论文旨在设计一款利用波分复用技术、具有数据时钟恢复、数字诊断功能、多速率光发送和接收一体化的光模块CFP (C Form-factor Pluggable,即百吉比特可热插拔),支持的速率从9.95Gbps、10.3125Gbps到最高的速率11.3Gbps,并支持所有这些速率的数据编码。本论文在调研40G技术的发展与应用的基础上,探讨了4OGbpsCFP光收发一体模块的基本工作原理、各器件选型,并给出了本课题的总体设计目标。然后对4OGbps CFP光模块的发射部分、接收部分、数字诊断监控部分、通信接口及电源部分进行了设计,并对CFP光模块如何保持信号完整性进行了详细分析。最后测试了40G CFP光模块的发射端和接收端的性能指标,并对其结果进行详细分析与总结。测试结果表明,所设计的模块各方面均满足性能指标要求,为4OGbps CFP光模块的产业化奠定了基础。
[Abstract]:With the rapid development of high-speed data service, people have higher and higher requirements for bandwidth. Nowadays, the most widely used 10Gbps Ethernet technology has gradually shown its limitations, and 40Gbps transmission service has become the focus of attention in the industry. The application of WDM (WDM) technology to 40Gbps transmission service can greatly improve the capacity and optical fiber utilization of optical fiber transmission system, on the other hand, it can make full use of the huge potential bandwidth of optical fiber. Therefore, in 40Gbps Ethernet technology, wavelength Division Multiplexing (WDM) technology can quickly provide new services with larger capacity and higher speed for the network, and make optical fiber communication have a broader development prospect. Nowadays, the function of data center is becoming more and more powerful, the data capacity of processing is larger and larger, 10G Ethernet transmission has been unable to meet the needs of people, the emergence of higher rate Ethernet transmission technology is imminent. To support the server to transfer more data at a higher rate. However, it is very difficult to send 100G beyond 100m, and the development time is much longer than expected, so 40G Ethernet transmission technology is put on the agenda as the transition of 10G and 100G Ethernet technology. The 40Gbpsoptical module, which matches the 40G Ethernet transmission technology, is also used. It can be compatible with the rate of 10Gbpsoptical module downwards, and can also serve the future 100Gbps optical module. Therefore, 40Gbpsoptical module has a broad market prospect. The purpose of this paper is to design an optical module CFP (C Form-factor Pluggable, which uses WDM technology, which has the functions of data clock recovery, digital diagnosis, and the integration of multi-rate optical transmission and reception). The supported rates range from 9.95 Gbps to 10.3125 Gbps to the highest rate of 11.3 Gbps, and all of these rates are supported for data coding. Based on the investigation of the development and application of 40G technology, this paper discusses the basic working principle of 4OBpsCFP optical transceiver module, the selection of each device, and gives the overall design goal of this subject. Then the transmitting part, receiving part, digital diagnosis and monitoring part, communication interface and power supply part of 4OGbps CFP optical module are designed, and how to maintain the signal integrity of CFP optical module is analyzed in detail. Finally, the performance indexes of the transmitter and receiver of 40G CFP optical module are tested, and the results are analyzed and summarized in detail. The test results show that the designed module meets the performance requirements in all aspects, which lays a foundation for the industrialization of 4OGbps CFP optical module.
