As of today, one of the three major science and technology, information technology has made the development of the explosive. In recent years, with the advent of new communication channel bandwidth requirements are increasing the transmission distance and bandwidth, fiber-optic communications have an unparalleled advantage. As an important part of the fiber-optic communication equipment, optical module in recent years the rapid development. Optical module to send and receive rates continue to increase, as well as the emergence of a variety of packages, such as 1 * 9 (9 Pins) GBIC (Gigabit Interface Converter), SFP (Small Form-factor Pluggables) SFP (SFP expansion) X2 (X-wavelength Two ports) and XFP (10 Gigabit Small Form Factor Pluggable). XFP 10G modules more popular for the moment, due to the rapid development of 10G Ethernet, so research XFP modules have a more realistic sense. This article \and testing program. This paper will first analyze some of the characteristics of the fiber channel, expand the channel dispersion and dispersion overcome specific exposition, fiber and module coupled theory. On the hardware side, it will give a specific circuit. Designed in this paper XFP circuit transceiver chip Si5040, TOSA (Tansmitter Optical Subassembly) using the EML, ROSA (Receiver Optical Subassembly) with the APD, and microcontroller using F311, using XFI interface fully compliant with XFP MSA regulations, with hot-swappable nature. The circuit can be programmed to debug power and extinction ratio, and has a digital diagnostic functions. Fully consider the high-speed circuit, circuit design and PCB layout process, signal integrity analysis. I set up a test system of the eye diagram, analyze the various causes of poor eye diagram given circuit debugging method, a higher quality of the originator signal eye diagram. Test section, using the the Tektronix company's CSA8200 optical eye diagram analysis, BERT E6010 using Instelent Company BER test, both instruments at the core, I set up the automated test system, and to write software, test its closing end and the originator of the indicators, the software Labview and C language mixed programming Practice has proved that this method is scientific and effective, and improve production efficiency. Designed in this paper XFP completely meet the XFP MSA IEEE802.3ae requirements.
