本文规定的性能要求包括连接至背板印刷电路板（PCB）、连接至主板或直接安装至电路卡机架后缘的连接器插头。配套连接器插座安装在插入背板PCB、主板或机架的PCB的后边缘。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，连接器的两半部分将与电路卡、主板或机架上的锁定功能固定在一起。单光纤电缆在与后壳一起使用时的防电缆进入功能包括限制移动、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 plug that is affixed to a backplane printed circuit board (PCB), affixed to a motherboard, or mounted directly onto the back edge of a circuit card rack. The mating connector receptacle is mounted at the back edge of the PCB that is inserted into the backplane PCB, motherboard, or 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, the connector halves are held together with the locking features on the circuit card, motherboard or rack. Cable entry 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.
