本文规定的性能要求包括仅用于光纤应用的MIL-PRF-64266或MIL-DTL-38999连接器插头或插座的后壳。该后壳适用于电缆束配置，其中一束单芯光缆（单工光缆）穿过电缆包等材料，到达连接器插头或插座。该后壳用于与一端的连接器插头或插座连接，并包含一个接口（平台），用于用另一端的捆扎带固定电缆缠绕。作为替代方案，该平台可用于将电缆应变消除（如热收缩）固定到后壳的电缆入口端。 抗环境特性包括能够限制每根电缆的移动、位置和扭曲，以及消除或减少各种环境的渗透。这个后壳是一个坚固的外壳结构。这种结构包括两端带有连接螺母的实心外壳（或主体）、压盖组件和捆扎适配器/电缆应变消除接口组件。外壳上的一个连接螺母与连接器匹配，另一个则包含压盖，并与带状适配器/电缆应变消除接口匹配。

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. Environmental resistant features include ability to restrict movement, position, and twist of each cable in addition to eliminate or reduce penetration of various environments. This backshell is one of a solid shell configuration. This configuration consists of a solid shell (or body) with coupling nuts on both the ends, gland components and banding adapter/cable strain relief interface components. One coupling nut on the shell mates with the connector, the other both houses the gland and mates with a banding adapter/cable strain relief interface.
