100Gbps CFP2 LR4光模塊的研究與設計
[Abstract]:With the rapid development of mobile Internet, convergence of three networks, Internet of things, cloud computing, video and other large bandwidth Internet applications, the bandwidth pressure of optical communication backbone network is increasing day by day. It is imperative to greatly improve the transmission capacity of optical communication networks. For DWDM optical communication transmission system, one way to increase transmission capacity is to use 100Gbps (100G) optical communication technology to improve the transmission rate of optical communication channel. 100G optical module, as the key technology of 100G optical communication, is a complex technology, and the cost is still very high, which restricts the development of 100G optical communication to a certain extent. Therefore, speeding up the development of 100G optical module technology, designing optical modules that conform to optical communication protocol, consume less power, encapsulate smaller structure and lower cost become the key to promote the development of optical communication. The purpose of the research and design of 100Gbps CFP2 LR4 optical module is to solve the above problems and to meet the market demand for 100G optical module. The package size of the 100Gbps CFP2 LR4 optical module studied in this paper is only 111.6x41.5x17.4 mm, which is outputted by four optical wavelength channels. The maximum modulation rate of each optical signal is 27.952493Gbps. the maximum optical fiber transmission distance is 10km, which accords with 802.3ba. CFP2 MSA and other protocols specify the definition of CFP2 optical modules. In this paper, the research significance of 100G optical module is defined by introducing the research background of 100G optical module, then the relative protocols of 100G optical module are introduced, and the design index of commercial 100Gbps CFP2 LR4 optical module is determined according to the requirements of the protocol. Then the key device technology in the design of 100Gbps CFP2 LR4 optical module is introduced. The laser automatic temperature control, automatic optical power control, module communication design and PCB design are described in detail. Finally, the 100Gbps CFP2 LR4 optical module is tested and systematically analyzed, and the measures to optimize and perfect the optical module in the following work are put forward.
