Hex Registry Tuning
Full hex registration tuning reduces losses caused by fiber and core eccentricity for consistent single-mode, multimode, and angle-polish performance.
NXTCore Optical Terminus System
A feature-rich, fully compliant ARINC 801 terminus platform with proprietary hex registry tuning and configurations for loose, tight, and 900-micron cable constructions.

NXTCore details
NXTCore brings hex registry tuning to the ARINC 801 interface, allowing termination variation and fiber-core eccentricity to be reduced for stable random-mate optical performance.
The platform is fully intermatable and interchangeable with other compliant ARINC 801 termini and can be used in standard circular and rectangular ARINC 801 connector systems.
NXTCore advantages
Full hex registration tuning reduces losses caused by fiber and core eccentricity for consistent single-mode, multimode, and angle-polish performance.
Passivated stainless-steel high-stress components and heavy-nickel-plated sliding elements support durable movement and connector compatibility.
Pre-set stainless-steel springs maintain repeatable contact force through hundreds of mating cycles.
Japanese-manufactured zirconia ferrules control concentricity and diameter within half a micron for stable low-loss connections.
A dedicated 900-micron sub-jacketed-fiber configuration provides strain relief for sensitive optical cabling inside electronic boxes and racks.
NXTCore works with commercially available ARINC 801 connector systems and XiOptics specialty adapter solutions.
Cable construction options
Designed for loose-construction cables where the terminus provides integrated cable-load management and strain relief.
Configurations for tight-construction and sub-jacketed fibers preserve the standardized ARINC 801 mating interface while matching cable architecture.
