此处规定的性能要求包括用于仅光纤应用中的MIL-PRF-64266或MIL-DTL-38999连接器插头或插座的后壳。此后盖适用于线束配置，其中一束单光纤电缆（单工光缆）通过电缆包等材料布线至连接器插头或插座。该后壳用于与一端的连接器插头或插座接口，并包含一个接口（平台），用于用另一端的束带固定电缆包。作为替代方案，该平台可用于将电缆应力消除（如热收缩）固定到后壳的电缆入口端。此后壳是一种实心壳配置。 该配置包括一个固体外壳（或主体）、一端的连接螺母和另一端的捆扎适配器/电缆应力消除接口组件（无压盖）。外壳上的连接螺母与连接器配合。

The performance requirements specified herein cover a backshell intended for use with a MIL-PRF-64266 or MIL-DTL-38999 connector plug or receptacle in a fiber optic only application. This backshell is intended for the cable harness configuration in which a bundle of single fiber cables (simplex optical cables) are routed through material, such as cable wrap, to the connector plug or receptacle. This backshell is used for interface with the connector plug or receptacle on one end and contains an interface (platform) to secure the cable wrap with a banding strap on the other end. As an alternative, this platform may be used to secure a cable strain relief (such as heat shrink) to the cable entrance end of the backshell. This backshell is one of a solid shell configuration. This configuration consists of a solid shell (or body) a coupling nut on one end and banding adapter/cable strain relief interface components (no gland) on the other end. The coupling nut on the shell mates with the connector.
