AllFiber Splice Code
Cross-brand fusion splicer error code lookup, fully offline. Your Fujikura throws "Focus X Motor Overrun." Your buddy's Sumitomo throws "Brightness Error." Same root cause — different brand wording. AllFiber Splice Code maps them all and tells you the fix without leaving the manhole. Coming soon to iOS and Android.
The problem it solves
Every fusion splicer vendor invents its own error-code vocabulary. The same fault — a dirty V-groove, a bad cleave, a motor overshoot — shows up under different names on Fujikura vs Sumitomo vs Ilsintech Swift vs INNO. Vendor manuals are 200+ page PDFs locked behind serial-number paywalls and you can't open them in a vault anyway.
AllFiber Splice Code is a single 156 KB offline database of every documented error code across 10 manufacturers and 84 splicer models, with field-fix steps and cross-brand equivalents.
What's covered
197 documented error codes across these manufacturers:
| Manufacturer | Models covered | Error codes |

| Fujikura | 90S+, 90S, 90R, 70S, 62S, 22S, 18S, FSM-40S, DVP series | 41 |
| Sumitomo | Type-Q101, Q102, 71C+, 72C+, 82C+, T-400S, T-66M12, T-Z1C | 27 |
| Ilsintech Swift | S3, S5, S7, KF4, KF4A, K11A, K33A, KR25 | 23 |
| INNO Instrument | View 3, 3X, 5, 7, 8, 8+, IFS-10, IFS-15 | 22 |
| Signal Fire | AI-5, AI-6, AI-6A, AI-7, AI-8, AI-8C, AI-9 | 9 |
| Fitel / Furukawa | S123, S153A, S178, S178A, S179, S179A | 14 |

| DVP | DVP-740, other series | 8 |
| Jilong | KL-series | 11 |
| EXFO | FTB-1, FTB-2 OTDR platforms, iOLM, inspection probes, power meters | 20 |
Cross-brand equivalence map
The same root cause often shows up under different names depending on the manufacturer. Splice Code groups these into 20 cross-brand equivalence groups. A few real examples from the database:
- Motor overrun on focus axis — Fujikura calls it "Focus X/Y Motor Overrun"; Sumitomo calls it "Brightness Error"; Ilsintech Swift calls it "Replace Position." All three point to the same fault: the focus motor traveled past its expected position.
- Dirty fiber surface — surfaces across multiple brands as "Cleaning Error," "Dust Error," or category "contamination." Same fix workflow: clean the V-groove, re-cleave, re-strip.
- Cleave-angle out of tolerance — same cleaver problem, different words. Many splicers report it numerically; Splice Code surfaces the LCD hash reference (e.g. #1908) inline with the code name.
Seven error categories
Every error in the database is tagged by category so you can filter by what just went wrong:
- Cleave — cleave angle, cleave length, cleaver-blade issues
- Positioning — V-groove alignment, motor errors, fiber-end position
- Contamination — dirty V-groove, dirty fiber, dust on optics
- Arc — electrode wear, arc calibration, arc test failures
- Splice — high loss, bubble detection, fiber-mismatch alerts
- System — battery, firmware, sensor, calibration faults
- Measurement — OTDR acquisition errors, live-fiber detection, wavelength faults (added for the EXFO test-platform scope)
Why offline matters
Fusion splicers live in places with no cell signal — underground vaults, fiber pedestals, aerial bucket trucks, locked-down corporate data centers. AllFiber Splice Code bundles its entire database with the app at install time. No network call, no spinner, no "please reconnect." Open the app, type the error or tap a category, get the fix. Splice Code follows the same offline-first principle as our existing app AllFiber Color Code.
Who it's for
- Fusion-splicing techs running multi-vendor fleets
- OSP crews who service their own splicers in the field
- Contract splicers moving between Fujikura and Sumitomo shops
- Training departments standardizing troubleshooting across crews
- OTDR test technicians (EXFO FTB-1, FTB-2, iOLM) running acquisitions in the field
Pricing
$4.99 one-time purchase at launch. Same as AllFiber Color Code. A future bundle (AllFiber Suite) will combine both apps at a discounted rate. Teams licensing with volume pricing will be available for crews of 5 or more.
Status
The app is built and in private testing. iOS submission is pending and Android will follow within days of the iOS approval. Use the "Notify me at launch" link above to get an email the moment listings go live, or follow updates on the AllFiber home page.
Frequently asked questions
Which fusion splicer brands does AllFiber Splice Code support?
Ten manufacturers: Fujikura, Sumitomo, Ilsintech Swift, INNO Instrument, Signal Fire, Fitel / Furukawa, FiberFox, DVP, Jilong, and EXFO. Across these, the app covers 84 splicer and test-platform models.
How many error codes are in the database?
197 documented error codes, organized into 7 categories. Each error has field-fix steps and — where applicable — cross-brand equivalent codes on other manufacturers.
Does it work offline?
Yes. The full database is bundled with the app at install time. Lookups work in vaults, manholes, cabinets, and aerial lifts where there is no cellular signal.
When will it launch?
iOS submission is pending and Android will follow within days of the iOS approval. Sign up for launch notification above and we'll email you the day it goes live.
