The “almost new” package we tested was remarkably complete, mirroring a brand-new kit. This comprehensiveness is a major part of the value proposition when you’re deciding should I buy Fujikura 70R splicer as a standalone investment. Inside the robust CC-39 carrying case, you’ll find:
The condition was pristine, with only “several hundred cores” welded, meaning it’s effectively broken in without significant wear. The organization within the case is logical, creating a ready-to-deploy field workstation.

Remove the splicer and CT50 cleaver from the case. Charge the BTR-09 battery using the DCC-18 cord and ADC-18 adapter. Assemble the left and right work trays onto the J-plate inside the lid of the carrying case. Mount the splicer onto the tripod screw for stability. This integrated setup is a hallmark of the system’s design, answering whether the Fujikura FSM-70R is worth buying for field efficiency with a resounding yes.
Power on the splicer using the battery or AC power. The intuitive color touchscreen will guide you through initial language and unit settings. Familiarize yourself with the main menu: Splice, Heat, Programs, and Settings. For ribbon splicing, ensure the correct ribbon program (e.g., for 250µm SWR) is selected. The CT50 cleaver requires its own simple calibration—follow the on-screen prompts when you connect it via Bluetooth on the 70R+ model.
Use the pitch conversion fiber holder (FH-70-12PC, often purchased separately) to convert 200µm pitch fibers to 250µm for splicing. Utilize the programmable feature memory to save custom parameters for unique fiber types. The Bluetooth system can monitor cleaver blade life; pay attention to these alerts to maintain optimal cleave quality. For maintaining all your fiber tools, consider investing in a full Fujikura kit for seamless compatibility.
Daily maintenance is minimal but critical. Use the VCB-01 brush to clean the fixed V-grooves. Clean the electrode tips with the provided alcohol swabs. Regularly clean the camera lenses with a dry, lint-free cloth. Store the unit in its case with the lid closed to prevent dust ingress. Our fusion splicer maintenance guide has more detailed protocols.
Issue: High splice loss or estimation error. Solution: Re-cleave the fiber. Ensure the fibers and V-grooves are impeccably clean.
Issue: Heater not activating. Solution: Check the heater door is fully closed and the correct heat shrink program is selected.

We deployed this almost-new FSM-70R+ kit over three weeks in varied scenarios: a controlled lab environment for baseline metrics, a data center for backbone splicing, and an outdoor FTTH deployment cabinet. We performed over 500 ribbon splices, using single-mode G.652.D and ribbon fiber.
The numbers tell a compelling story. The average splice loss consistently measured between 0.02 dB and 0.04 dB, well below the typical 0.05 dB specification. The 55-second total process time (cleave to heated sleeve) was achievable and repeatable. Battery life from the BTR-09 reliably provided a full day’s work (150+ splices) on a single charge. Consistency was its strongest suit—every splice felt and measured the same, with no drift in alignment quality.
In the windy, dusty FTTH cabinet, the mirror-less optical system and automated wind protector proved invaluable. Splice quality didn’t degrade despite the environment. In the data center, where speed during mass connector installation was key, the automated workflow saved hours. The transit case as a workstation eliminated fumbling for tools, keeping the work area organized and efficient.
Fujikura’s claims of ruggedness, speed, and low loss held up entirely in our testing. The Bluetooth tool management, while innovative, is most beneficial for large teams managing many tools rather than a sole operator. The core promise—that this is a best ribbon fusion splicer for fiber optic high-volume work—is absolutely valid. This hands-on experience is crucial for an honest Fujikura 70R+ honest assessment.
