Lightera will showcase next-generation fusion splicing innovations at DCW 2026, building on the proven FITEL^® S185 series of specialty splicer platforms with new advanced techniques designed specifically for hollow-core fiber (HCF) and multi-core fiber (MCF) alignment and splicing.

Information provided on booth M075 will feature enhanced imaging, precision rotational alignment, and adaptive arc control methods that address the unique structural and thermal sensitivities of emerging specialty fibers used in ultra-low latency, ultra-wideband, and high-density optical systems.

Advanced Techniques for HCF and MCF Splicing

Hollow-core fiber introduces new splicing challenges due to its air-guided core, thin ring-tube structure, and extreme temperature sensitivity. Multi-core fiber also presents unique alignment obstacles, driven not only by the presence of multiple cores but also by integrated orientation markers.  The Fitel S185 splicer addresses these alignment challenges through enhanced multi-feature imaging and advanced alignment algorithms designed for next-generation fiber structures.

Lightera’s DCW 2026 splicing showcase introduces advanced methods that extend S185-series capabilities to these emerging fiber types, including:

• End-View Cross-Section Imaging Alignment — real-time end face visualization to verify core geometry and rotational orientation, critical for MCF core mapping and alignment
• Advanced Alignment algorithm — side view image-based alignment techniques that confirm both multi-core and marker positional matching before fusion
• Uniform Circumferential Heating (“Ring-of-Fire” arc control) — distributed plasma heating to reduce asymmetric thermal stress on both MCF and HCF as well as to protect delicate HCF structures
• Sequential Multi-Electrode Arc Profiles — adaptive arc sequencing fine-tunes heat delivery for specialty fibers, supporting lower loss and improving splice strength and consistency

These techniques help preserve optical performance, minimize splice loss, and improve splice strength and repeatability when working with complex network systems.

Built on FITEL S185 Specialty Splicing Heritage

The FITEL S185 series has been widely adopted for specialty fiber applications including polarization-maintaining, large-diameter, and various specialty fibers. The DCW showcase demonstrates how this platform can be extended with advanced alignment algorithm and arc strategies to support:

• Hollow-core transmission systems
• Multi-core high-density fiber links
• Specialty photonics and sensing fibers
• Advanced research and production environments
