M28876/2B11S2 is the MIL-PRF-28876/2 wall mount receptacle, straight strain relief in shell code B (13) with socket termini and keying position 2. MIL-PRF-28876 (originally MIL-C-28876, released 1983 by NAVSEA/NAVAIR) is the US Navy performance specification for circular, multiple-removable-termini fibre-optic connectors used on shipboard top-side, ship-to-shore and harsh naval interconnect. The double-start ACME coupling thread and anti-decoupling ratchet resist the shock and vibration of MIL-S-901 Grade A service, and the shells accept MIL-PRF-29504/14 and /15 termini for single-mode and multimode cable. Receptacles are intermateable across the M28876/1 to /14 family and share the standard M28876 panel cut-out.
