scope:

The performance requirements specified herein cover a backshell intended for use with a MIL-DTL-38999 or MIL-PRF-64266 connector plug or receptacle in a fiber optic only application. This backshell is intended for an open cable harness configuration in which a bundle of single fiber cables (simplex optical cables) are routed to the connector plug or receptacle with no external protection. This backshell is used for interface with the connector plug or receptacle on one end and contains no interface on the other end. 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 nut on one end, a gland nut on the other end and gland components. The coupling nut on the shell mates with the connector. The gland nut on the other end of the shell secures the gland into the backshell.
