本文规定的性能要求包括固定在电路卡或印刷电路板（PCB）前边缘的连接器插座。将PCB插入背板或机架后，连接器插头与连接器插座的匹配完成。一旦位于PCB前边缘的连接器插座正确插入背板或机架，连接器的两半部分就会配对，然后使用螺旋千斤顶的功能拧紧在一起。单光纤电缆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 receptacle that is affixed to the front edge of a circuit card or printed circuit board (PCB). Mating of the connector plug to the connector receptacle is accomplished after the PCB is inserted into the backplane or rack. Once the connector receptacle, positioned on the front edge of the PCB, is correctly inserted into the backplane or rack, the connector halves are mated then tightened together using the feature of a jackscrew. Cable entry resistant features for the single fiber cables 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.
