The Fujikura FSM-88R is a dedicated mass fusion splicer designed primarily for splicing 12-fiber ribbon cables. It is positioned as the direct successor and replacement for the FSM-70R12, incorporating several key technological advancements while maintaining a focus on speed, reliability, and ease of use. This machine is aimed squarely at professional field technicians and data center installers who need to terminate high-fiber-count cables efficiently. The primary innovation here is the wide heating area and advanced arc control system, which ensures uniform melting across all 12 fibers simultaneously. Unlike some high-end models, the 88R does not use active core alignment; instead, it relies on the surface tension of melting fibers and precision V-grooves to achieve low splice loss. For more on Fujikura, you can see their engineering history. When you buy Fujikura FSM-88R mass fusion splicer, you are getting a tool that prioritizes throughput and reliability over the absolute lowest loss achievable with active alignment.

The 88R is packed with features that directly address the pain points of mass fusion splicing.

Upon unboxing, you will find a comprehensive kit that is ready for immediate fieldwork. The package includes: the Mass fusion splicer 88R, a Fiber Cleaver CT50, a Ribbon Fiber Stripper RS-03, a Battery Pack BTR-15, an AC Adapter ADC-20, an AC Power Cord ACC-14, a USB Cable USB-01, a Fusion Splicer Strap ST-02, one 12 Fiber-Groove VG12-01, a Hexagonal Wrench HEX-01, a V-groove Cleaning Brush VCB-01, a Carrying Case CC-39, Work Tray Left WT-09L, Work Tray Right WT-09R, a Tripod Screw TS-03, a Work Tray J-Plate JP-09, a Carrying Case Strap ST-03, an Alcohol Dispenser AP-02, and a Quick Reference Guide QRG-03-E. The packaging is robust, and every component feels durable. Our first impression was that this is a professional-grade system, not a consumer toy. The inclusion of a spare V-groove set pre-installed with electrodes is a standout, as it directly addresses the most common field failure point.

Start by connecting the AC adapter or inserting the charged battery pack. Open the wind protector and ensure the V-grooves are clean. Install the work trays on each side of the machine. The setup is intuitive and takes under five minutes.
Power on the unit using the main switch. The interface is menu-driven and similar to other Fujikura models. Navigate to the settings menu to select your fiber type (ribbon, 12-fiber) and sleeve length. The machine will self-calibrate upon first startup.
Strip the ribbon using the RS-03 stripper, cleave it with the CT50 cleaver, and place it in the FH-70-12 holder. Position the holder in the splicer and close the lid. The machine automatically aligns the fibers using the V-grooves, performs a brightness intensity check on the arc, and completes the splice in just seconds.
For pitch conversion of 200µm fibers, use the FH-70-12PC holder. For Spider Web Ribbon, ensure you use the 250µm pitch V-grooves in the standard holder for optimal loading. The real-time arc control can be manually adjusted if you encounter difficult fiber types.
After each use, clean the V-grooves with the included brush and alcohol dispenser. Replace electrodes per the manufacturer's schedule. Store the machine in its hard case to prevent dust contamination.
If the machine reports a bright arc error, clean the electrodes. If fibers do not align, check the V-grooves for debris and the cleaver blade for wear. Always carry the spare V-groove assembly for immediate field replacement.

We used the FSM-88R for three weeks in a mix of controlled lab environments and actual field installations. We tracked splice time, loss values, and error rates across different ribbon types.
In our testing, the 88R consistently completed a 12-fiber splice in under 10 seconds. Splice loss averaged 0.02dB, which is excellent for a mass fusion splicer without active alignment. The heater cycle for protection sleeves averaged around 25 seconds. The machine handled over 200 splices per battery charge without issue.
In outdoor conditions with moderate wind, the wind protector worked effectively. We tested it with both standard encapsulated ribbon and Spider Web Ribbon; the 250µm pitch V-grooves made SWR loading noticeably easier than on older models. The spare V-groove set saved us during a critical job when a groove got contaminated.
Fujikura claims the 88R is a direct upgrade to the FSM-70R12. Based on our experience, the improved arc control and replaceable V-grooves are genuine advancements. The “same machine as FSM-90R” claim also held up, as we observed identical performance. There is no noticeable performance gap that would make you consider the 90R over the 88R. After extensive use, we can confidently say this is a Fujikura FSM-88R worth buying.
