描述了一种紧凑型MU接口2.5Gb/s光发射模块。它采用了一个低功耗的LD驱动器IC（LD-DR），这是热隔离的1.55-/spl μ/m DFB-LD附加在TE冷却器。光连接器接口是位于微型同轴电插座相对侧的MU插座。采用了DFB-LD与单模光纤的高耦合方法。它由两个非球面透镜，这是在共焦条件下定位。已在10/spl deg/C至65/spl deg/C的温度范围内对使用所提议配置的模块进行了评估。采用6.2cc组件，在2.5Gb/s的传输速率下，获得了50%以上的高耦合效率、小于1.8W的低功耗（LD-DR仅消耗0.33W）和良好的电性能。该模块体积小、功耗低，适用于未来SDH、WDM等大容量系统所需的高集成度车载设备。
A compact MU interface 2.5-Gb/s optical transmitter module is described. It employs a low power consumption LD-driver IC (LD-DR) which is thermally isolated from the 1.55-/spl mu/m DFB-LD attached on a TE-cooler. The optical connector interface is an MU receptacle positioned at the opposite side of the electrical miniature coaxial receptacles. The high coupling method of a DFB-LD to a single mode fiber is used. It consists of two aspheric lenses which are positioned under a confocal condition. The module using the proposed configuration has been evaluated from 10/spl deg/C to 65/spl deg/C. Good results of high coupling efficiency over 50%, low dissipation power less than 1.8 W (LD-DR only dissipated 0.33 W), and electrical performance at the speed of 2.5 Gb/s have been obtained with the 6.2-cc module. This compact module with low consumption will be useful for highly integrated on-board equipment required for large-capacity systems such as future SDH and WDM systems.
