Mainstream Models of Optical Cable Fusion Splicing Machines

Leading fusion splicers include Fujikura FSM-90S+, INNO View 8+, Sumitomo Type-72C+, and KOMSHINE FX39, offering precision core alignment, fast splice times, and smart features for modern fiber optic networks.

Overview of Fusion Splicing

Fusion splicers join two optical fibers end-to-end using an electric arc, creating a permanent, low-loss connection essential for high-speed data transmission in FTTH, FTTx, and data center networks . They are categorized mainly into single-fiber splicers, which handle individual fibers for repairs or low-volume installations, and ribbon splicers, capable of fusing multiple fibers (up to 12) simultaneously, ideal for high-density environments .

Mainstream Models

• Fujikura FSM-90S+: Industry-leading core alignment splicer with high-precision lenses, automatic fiber discrimination, and optimized splice/heat times (7s splice, 9s heat). Suitable for backbone and professional-grade installations .
• INNO View 8+: Offers IPAS core-to-core alignment, multi-language interface, and robust environmental resistance. Designed for both single-mode and multi-mode fibers, supporting field and indoor applications .
• Sumitomo Type-72C+: Known for durability and fast splice cycles, with automated calibration and low splice loss, making it suitable for telecom and large-scale FTTH deployments .
• KOMSHINE FX39 / EX39 Mini: Budget-friendly options with 6-motor core alignment, compact design, and mobile app integration for monitoring splicing performance .

Key Features to Consider

• Alignment Technology: Core alignment ensures minimal signal loss (as low as 0.02 dB), while cladding alignment is more cost-effective for residential FTTH projects .
• Splice and Heat Speed: Modern splicers achieve splice cycles in 5–8 seconds and heating in 8–15 seconds, improving field efficiency .
• Portability and Battery Life: High-capacity lithium batteries (up to 7800 mAh) allow extended field operations without frequent recharging .
• Smart Features: Cloud syncing, automated arc calibration, and mobile app connectivity enhance workflow management and data tracking .
• Environmental Resistance: Many models are dust, water, and shock-resistant, suitable for outdoor and challenging conditions .

Market Trends

The fusion splicer market is shifting toward automation, AI integration, and all-in-one workstations, driven by 5G and FTTH expansion, particularly in Asia-Pacific. High-end core alignment splicers dominate the professional segment, while value-focused cladding alignment and smart splicers cater to emerging technology and budget-conscious users . Ribbon splicing for 12 fibers simultaneously is becoming standard in high-volume installations, emphasizing speed and consistency .

Conclusion

Selecting the right fusion splicer depends on project scale, fiber type, budget, and required features. For high-density or backbone networks, Fujikura FSM-90S+ or Sumitomo Type-72C+ are preferred, while INNO View 8+ and KOMSHINE models offer versatility and cost efficiency for FTTH and smaller projects. Proper training, maintenance, and calibration are essential to ensure long-term reliability and optimal performance .
