Fiber Optic Fusion Splicer – Yamasaki Y91

The Yamasaki Y91 Fusion Splicer combines cutting-edge alignment technology with portability, making it one of the most versatile splicing tools in its class. Built for fiber-to-the-home (FTTH), telecommunications, and data centre networks, the Y91 delivers professional-grade splices in a lightweight design that’s easy to carry anywhere.

Unlike bulky traditional splicers, the Y91 is compact, fast, and engineered for contractors who need reliable performance on-site without compromising accuracy.

fibresales is proud to supply the Y91 Fusion Splicer in Australia, backed by warranty and technical support.

Why the Y91 Fusion Splicer is Different

• Six-Motor Core Alignment
  While standard splicers often use 2 or 4 motors, the Y91’s 6-motor design ensures ultra-precise fibre alignment. This reduces splice loss dramatically:

  • 0.02 dB typical for Singlemode

  • 0.01 dB typical for Multimode

• Faster Workflow
  With 6-second splice time and 18-second heat time, technicians can complete projects faster, reducing downtime and labour costs.

• True Portability
  At just 2.45 kg, the Y91 is easy to carry to rooftops, manholes, or cramped data centre racks. Its small footprint (156 × 141 × 156 mm) makes it practical for tight spaces.

• Simplified Controls
  The Y91 is designed for both experts and newcomers, offering touchscreen + keypad operation. This flexibility makes it easy to learn while still powerful for advanced technicians.

• Long-Lasting Battery
  A 5200mAh Li-ion battery powers up to 250 splice and heat cycles per charge, making it reliable for all-day jobs.

Added Usability Features

• Multilingual Interface – English, Spanish, Portuguese, French, Italian, and German menus for global deployment.

• Bi-Directional Display – Flip the 5-inch LCD screen for better positioning in awkward spaces.

• Adjustable USB LED Light – Essential for contractors working in dark locations.

• Program Test Function – Automatically fine-tunes arc parameters for different fibre types, saving time and reducing errors.

• Data Storage – Holds up to 10,000 splice results, accessible via USB for reporting or compliance.

• Rugged & Reliable – Withstands -20°C to +50°C temperatures, up to 5000m altitude, and strong winds up to 15 m/s.
