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 one of a split (clam shell) shell configuration consisting of a front adapter, rear adapter, two (split) shell halves, and heat shrink sleeves. This backshell is intended for cable end interface with a multiple fiber cable with an arimid yarn type strength member. Two rear adapter configurations allow capture of the multiple fiber cable strain relief by either banding strap or compression fitting. Environmental resistant features include ability to restrict movement, position, and twist in addition to eliminate or reduce penetration of various environments.
