摘要： A dust cap is provided that includes a translucent end member that permits optical communication while the dust cap remains mounted upon a ferrule. The dust cap includes a sleeve having an open first end and an opposed second end that is closed by the translucent end member. The end member can also include a lens to facilitate optical communication. A medial portion of the sleeve can also define an internal chamfer that extends radially inward for engaging the ferrule such that the front face of the ferrule is spaced from the second end of the sleeve, thereby preventing contaminants from being transferred from the second end of the sleeve to the polished front face of the ferrule. The dust cap can also define a groove extending lengthwise through only a portion of the sleeve, i.e., from the first end of the sleeve to a medial portion of the sleeve. The groove therefore permits air to vent from the bore while the dust cap is being mounted upon the ferrule, while isolating the front face of the ferrule from the external environment once the dust cap has been fully mounted, thereby protecting the polished front face of the ferrule from contaminants that may enter the groove. A method is also provided for testing the continuity of an optical fiber jumper that utilizes optical communications conducted through the translucent dust caps.
摘要翻译：提供防尘罩，其包括透光性端部构件，其在防尘帽保持安装在套圈上时允许光学通信。防尘盖包括具有敞开的第一端和由半透明端部件封闭的相对的第二端的套筒。端部构件还可以包括用于促进光学通信的透镜。套筒的中间部分还可以限定内径倒角，其径向向内延伸以与套圈接合，使得套圈的前表面与套筒的第二端间隔开，从而防止污染物从第二端传递套筒到套圈的抛光前面。防尘盖还可以限定纵向延伸通过套筒的一部分，即从套筒的第一端到套筒的中间部分的凹槽。因此，当防尘盖被安装在套圈上时，槽能够使空气从孔中排出，同时一旦防尘盖完全安装就将套圈的前表面与外部环境隔离，从而保护了抛光的正面套圈可能会进入凹槽内的污染物。还提供了一种用于测试光纤跳线的连续性的方法，该光纤跳线利用通过半透明防尘盖进行的光通信。

摘要： A guide pin for mating multi-fiber optical ferrules includes a first end, a second end and a flexile feature adjacent to the second end. The first end has a first end width and the second end has a first engagement width and may change to a second engagement width while engaging a guide pin bore in a ferrule. The change in width permits the guide pin to engage and axially align with guide pin bores of varying diameters to achieve reliable optical mating of optical wave guides.
摘要翻译：用于配合多光纤光学套圈的引导销包括与第二端相邻的第一端，第二端和柔性特征。第一端部具有第一端部宽度，并且第二端部具有第一接合宽度，并且可以在与套圈中的引导销孔接合的同时改变为第二接合宽度。宽度的变化允许导销与不同直径的导销孔接合并轴向对齐，以实现光波导的可靠的光学配合。
