Identify what the display actually reports
The Furukawa Electric S185 issue-16 manual records left and right cleave angles, relative angle, program and estimated loss separately. It also distinguishes angle, end-face, bubble and estimated-loss errors. Those are useful process fields, not one complete optical acceptance result. 1
Cleave angle describes preparation before joining; estimated loss evaluates the splice under the machine's method. A small angle does not measure connectors, the entire fiber or the protected assembly.
This guide addresses pigtails, splice modules and OEM delivery records. It reviews evidence after splicing rather than repeating the choice between mechanical and fusion joining.
Three evidence layers
| Record | Typical content | Review purpose | Not automatically covered |
|---|---|---|---|
| Preparation | End-face image, angle and cleanliness | Whether processing should continue | Final optical acceptance |
| Splicer history | Program, alarms, estimate and sample ID | Approved process execution | Independent measured loss |
| Optical test | Object, reference, wavelength and method | Results within the stated boundary | Untested parts or mechanical lifetime |
| Protected state | Sleeve, routing, restraint and retest | Coverage of the delivered configuration | Other routes and environments |
This is a handover recommendation, not a fixed screenshot requirement. Link each record to its process stage and identifiable assembly.
Estimation has its own applicability
The S185 manual describes adjustment of estimated loss against actual loss. It requires separate measurement equipment and specific program/fiber conditions. That distinguishes an estimate from a measurement and limits the feature to its documented scope. 1
A buyer need not edit estimation parameters. When the supplier changes a program or fiber combination, request its approval basis and correlation with independent testing. A changed threshold, suppressed alarm or different display format is not evidence of optical improvement.
For results near a contractual limit, apply the agreed measurement and uncertainty decision rule. More displayed digits do not independently establish better accuracy.
Connect preparation, protection and final testing
Fujikura's cleaning guide identifies coating debris and contamination of the cleaver and clamping areas as contributors to poor preparation. Repeated anomalies warrant a preparation and maintenance review under the actual equipment instructions. 2
Panduit's fusion-splicing document also distinguishes the machine estimate from subsequent optical testing. Match the project method to length, event spacing and purpose rather than assigning one instrument setup to every short assembly. 3
| Stage | Suggested record | Acceptance authority |
|---|---|---|
| Preparation | Both fibers and preparation checks | Approved process document |
| Joining | Machine, program, alarms and estimate | Process owner |
| Protection | Sleeve, packaging and routing state | Assembly design and instructions |
| Measurement | Wavelength, reference, ports and method | Project optical specification |
| Delivery | Assembly ID, revision and disposition | Agreed acceptance procedure |
For an assembly containing connectors and several splices, identify the extent of the complete loss measurement. If an individual event must be assessed, verify that the method can resolve it under the actual length conditions. Overall loss and event location may require separate records.
No universal cleave-angle or splice-loss threshold is proposed here, and no claim is made that ARRANEX uses a named machine. Set limits for the approved configuration.
Procurement FAQ
- Does 0.00 dB on the display mean zero loss? No. Read the estimate definition and display resolution, then obtain the agreed independent test.
- Does no alarm mean the finished assembly passes? Alarm checking has a defined scope; apply the order's final acceptance conditions.
- Should every fiber use one cleave-angle limit? Use the approved fiber, process and equipment requirements.
- Is evidence needed after protection? Qualification must cover the delivered state; define any retest and its timing.
- What if only splice screenshots are supplied? Request sample IDs, program and exception records, plus the specified optical method, reference and results.
