Engineered details that improve performance
These core features are carried across XiOptics product families wherever the applicable interface and configuration allow.
Compression Springs
Pre-set, precision-ground 17-4 stainless-steel springs maintain consistent product performance through hundreds of mating cycles.
Ceramic Components
Precision ceramic ferrules control concentricity and diameter within half a micron, reducing installed-fiber eccentricity and improving insertion-loss stability.
Tuning
NXTCore™ ARINC 801 termini incorporate hex registry tuning to deliver lower and more consistent loss characteristics across fiber types.
Strength Member Termination
M29504 products offer either bonding-cup termination or adhesive-lined heat-shrink methods for strength members or outer jackets. ARINC 801 products offer either metallic crimp-ring termination or bonding-cup termination for strength members or outer jackets.
Rigorously Tested and Field Proven
All XiOptics products are rigorously tested at US DoD-approved fiber-optic test laboratories for performance across extreme thermal and mechanical environments. Testing protocols include MIL-PRF-29504 and ARINC 801. Independent laboratories ensure the quality of test results, and XiOptics makes summaries of those test results available to all customers. Over 25 years of global usage in mission-critical applications without failures demonstrates the capability of the products in avionics, marine, space, and industrial applications.
