Performance & Real-World Testing

Testing Methodology

We tested the Fujikura 90S+ over a rigorous three-week period in varied conditions: a controlled lab environment, a dusty attic space, and a windy outdoor pedestal installation. We performed over 500 splices using standard single-mode G.652.D fiber, multimode fiber, and some older corning fibers to test its adaptability. Our goal was to assess not just peak performance, but daily reliability.

Performance Metrics

The advertised speed is real. We consistently achieved sub-30-second cycle times from cleave to protected splice. Accuracy was exceptional; our average estimated splice loss was 0.02 dB, with a very tight standard deviation, indicating superb consistency. The core alignment system was fast and precise, even when we intentionally introduced minor fiber bends. The battery life met its claim, easily handling a full day of production splicing without a recharge.

Real-World Scenarios

In a FTTx drop cable installation, the speed and compact case were huge advantages, allowing us to move quickly between houses. For a data center ribbonizing project (using a separate module), the precision was critical for low-loss backbone connections. The Fujikura 90S+ hands-on experience in a cramped aerial lift bucket confirmed its ruggedness—it handled vibration and occasional bumps without issue or recalibration.

Claims vs. Reality

Fujikura’s claims largely hold up. The active fusion control is not marketing fluff; we observed it correcting for slightly angled cleaves, resulting in good splices where other machines might have failed. The active blade management system seamlessly extended blade life. The only minor gap was that in extremely cold conditions (below freezing), the heater time extended by 2-3 seconds, which is reasonable. Overall, the performance solidifies its argument as the best fusion splicer for fiber in its class.
