During our review unboxing, we found the package to be incredibly comprehensive. You are not just getting the splicer; you are getting an entire kit. This makes the value proposition even stronger in our Fujikura FSM-90R review honest opinion. Here is everything included:
The packaging is robust, with everything fitting neatly into the CC-39 carrying case. The build quality of the accessories, particularly the CT50 cleaver and RS03 stripper, matches the high standard of the splicer itself. As we noted in this review, the inclusion of a spare set of V-grooves and electrodes is a standout benefit, saving you significant money and hassle later.

Setting up and using the FSM-90R is straightforward, but there is a learning curve for mass fusion splicing. In our Fujikura FSM-90R review and rating, we followed the official guide and have compiled a step-by-step process for you.
Our review process began with unboxing. First, place the splicer on a stable, level work surface. Attach the work trays (WT-09L and WT-09R) to the sides of the splicer. Connect the AC adapter to the splicer and power it on. If using battery power, install the BTR-15 battery pack. The initial boot-up takes about 30 seconds. During our review, we found the interface to be intuitive, with a clear LCD screen and logical menu navigation.
After powering on, check the arc count. Ours was 368. You will need to perform a test splice to calibrate the arc power. Go to the maintenance menu and select “Arc Calibration.” Insert a piece of ribbon fiber into the splicer and close the lid. The machine will run a series of arcs to optimize the power. This is a critical step as noted in this Fujikura FSM-90R review honest opinion.
For daily splicing, the process is simple. First, strip the ribbon fiber using the RS03 thermal stripper. Second, cleave the fiber using the CT50 cleaver. Third, place the fiber in the V-grooves. Close the wind protector and press the “Set” button. The machine will automatically align, fuse, and splice the fibers. The entire cycle for 12 fibers takes under 15 seconds. Our review found the speed to be exceptional.
Experienced users can access advanced settings. The machine allows you to adjust arc power, splice time, fiber overfeed, and splice loss limits. You can also save custom programs for different fiber types (SM, MM, DS). During our review, we tested the pitch conversion feature using the FH-70-12PC holder. This allows you to splice individual 200µm fibers at a 250µm pitch for compatibility with standard ribbon splicers.
Daily maintenance is essential for optimal performance. After every 100 splices, clean the V-grooves and electrodes using the included VCB-01 brush. For deep cleaning, use lint-free swabs and isopropyl alcohol. Replace the electrodes after approximately 3000 arcs. The replaceable V-groove system is a highlight — you can swap them out in under five minutes. This is why this Fujikura FSM-90R review pros cons analysis will be very positive.
The most common issue in our review was poor fiber cleave leading to high splice loss. Ensure the CT50 cleaver’s blade is rotated regularly. If the machine displays “Arc Loss” errors, run the arc calibration again. For persistent problems, check the V-grooves for debris. The user manual provides detailed error codes. For more tips, read our article on fusion splicer troubleshooting.

Our hands-on performance review involved three weeks of daily use in a controlled workshop environment. We tested the FSM-90R on both single-mode and multimode ribbon fibers. This section of our Fujikura FSM-90R review and rating will detail the results.
We tested the splicer in a temperature-controlled environment (72°F) and in a slightly dusty field scenario. We performed over 500 splices total, using 12-fiber ribbons. We measured splice loss using an OTDR and calculated average values. This is an honest Fujikura FSM-90R review honest opinion based on quantitative data.
Our performance review found the following key metrics:
These numbers are impressive for a mass fusion splicer. The consistency across all 12 fibers was excellent, with very little variation in loss values. During our review, the machine handled the workload without any overheating or performance degradation.
We simulated a fiber-to-the-home (FTTH) installation. The splicer performed reliably, handling ribbons of different specifications without issue. The low arc count of 368 meant the electrodes were fresh, providing stable arcs from the start. In our review, the RS03 stripper proved invaluable, consistently stripping even 400µm coated fibers cleanly.
Fujikura claims the FSM-90R can splice 12 fibers in under 15 seconds. Our review validated this claim. We measured an average of 12 seconds. The claim regarding the surface tension alignment minimizing offsets also held true — the splice loss was consistently low. The only minor discrepancy in our Fujikura FSM-90R review honest opinion is the heater time. It is slightly longer than some modern single-fiber splicers, but that is expected for mass fusion.
After extensive use, we have compiled a balanced list of pros and cons. This is the definitive Fujikura FSM-90R review pros cons section.
How does this splicer stack up against its rivals? In this section of our Fujikura FSM-90R review and rating, we compare it to two main competitors.
