本文规定的性能要求包括固定在印刷电路板（PCB）电路卡后缘的连接器插座。匹配的连接器插头固定在背板PCB上，固定在主板上，或直接安装在电路卡机架的后缘上。将PCB插入背板、主板或机架后，通过盲配完成连接器插头与连接器插座的匹配。一旦连接器插座正确插入背板、主板或机架，单光纤电缆的抗干扰功能（当与后壳一起使用时）包括限制移动、位置和扭曲的能力；但是，没有任何功能可以捕获布线或防止各种环境的渗透。

The performance requirements specified herein cover a connector receptacle that is affixed to the back edge of a circuit card of printed circuit board (PCB). The mating connector plug is affixed to a backplane PCB, affixed to a motherboard, or mounted directly onto the back edge of a circuit card rack. Mating of the connector plug to the connector receptacle is accomplished by a blind mate after the PCB is inserted into the backplane, motherboard or rack. Once the connector receptacle is correctly inserted into the backplane, motherboard or rack, resistant features for the single fiber cables, when used with a backshell, include ability to restrict movement, position, and twist; however, there are no features to capture the cabling or to prevent the penetration of various environments.
