Stainless-Steel Bodies
Precision-machined and passivated stainless-steel metallic components provide a durable, non-corrosive foundation compatible with established connector platforms.
Qualified Optical Termini
MIL-PRF-29504
Precision Termini
Qualified, stainless-steel termini for industry-standard military and aerospace connector cavities, engineered for repeatable low-loss performance and practical field termination.
MIL-PRF-29504 details
Qualified performance, modern termination
XiOptics MIL-PRF-29504 termini are fully compliant with the specification and combine precision materials with current termination methods. Product options support single-mode, multimode, and plastic optical fiber applications.
Style 2 designs use a bonding-cup solution to capture strength members and the cable jacket without requiring external heat-shrink processing. Style 1 designs remain available for legacy programs.

Design advantages
Precision where performance depends on it
Controlled Spring Force
Pre-set stainless-steel springs maintain consistent contact force and optical performance through repeated mating cycles.
Precision Ceramic Ferrules
Ferrule concentricity and diameter are controlled within half a micron to reduce fiber eccentricity and stabilize insertion loss over product life.
Field-Ready Termination
Bond, cure, and polish processes are compatible with modern hand and automated termination methods, including fast thermal-cure epoxy systems.
Style 2 Bonding Cup
The integrated bonding cup captures strength members and jacketing without cumbersome post-termination heat-shrink sleeves.
Cross-Mate Compatibility
Style 1 and Style 2 termini can be cross-mated while preserving the standardized optical interface.
Four standardized interfaces
Matched to the connector platform
/4 Pin and /5 Socket
Size 16 termini for MIL-DTL-38999 connector systems, offered as QPL-certified military products and commercial versions where applicable.
/6 Pin and /7 Socket
Size 16 optical contacts for ARINC 600 and ARINC 404 gang inserts where electrical, RF, power, and optical paths share one connector system.
