摘　　要：文章介绍了应用于光网络系统的10Gbit/s XFP(小型化可热插拔)光模块的基本原理以及光收发模块的设计,采用了CDR(时钟数据恢复)、APC(自动功率控制)、LA(限幅放大器)和发射驱动集成的主芯片GN2010EA,与传统设计相比不仅降低了设计成本,而且降低了设计的复杂度。测试结果表明,该模块在宽的温度范围内能保持稳定的光功率和消光比,并且指标满足ITU-T标准的要求,符合10Gbit/s光模块设计要求。This paper introduces the basic working principles of 10 Gbit/s Small Form-Factor Pluggable Transceiver（XFP） applied in SONET systems and describes the design of the optical transceiver modules that conforms to the relevant standards.Comparing with the conventional design,this module reduces both the cost and complexity of the design thanks to the adoption of the main chip GN2010EA,on which bi-directional CDR,APC and LA and laser driver are integrated.The test results show that this module can emit light with stable optical power and extinction ratio over a wide range of temperature.Furthermore,its parameters satisfy the requirements of ITU-T standard and meet the design requirements for 10 Gbit/s XFP modules.
