Welcome to Fluke Fiber 10: Capstone: Certifying a Complete Fiber Project
Course Duration: 35–45 minutes
The final course of the series is a full project: OM4 horizontal links, MPO data-center trunks, and a singlemode campus backbone. You'll read the specification, plan and set up LinkWare Live and the testers, certify with the CertiFiber Pro and MultiFiber Pro, characterize the backbone with the OptiFiber Pro, handle failures the right way, and close out with a complete documentation package.
What You'll Learn:
- Read a project specification and turn it into a test plan
- Calculate expected budgets and set up projects, cords, and tools
- Certify horizontal links and MPO trunks correctly
- Run Tier 1 and Tier 2 on a singlemode backbone with SmartLoop
- Handle failures honestly and deliver a complete close-out package

Section 1: The Project Brief
In this capstone you certify a complete project, start to finish, applying everything from courses 1–9.
PROJECT: Riverside Medical — Building A refresh + campus backbone
• Horizontal fiber: 96 OM4 duplex LC links, telecom rooms → zone enclosures, ≤ 90 m,
2 mated connections each (panel at each end)
• Data center: 24 OM4 12-fiber MPO trunks (polarity Method B) between rows
• Campus backbone: 1.2 km OS2 loose-tube, Building A ↔ Building B, LC/APC panels,
2 mated connections + 2 fusion splices per fiber
• Specification: TIA-568.3-E limits; Tier 1 on all fiber; Tier 2 (OTDR) on the backbone;
1-jumper reference; end-face images saved; manufacturer 25-year warranty registration
Read the specification first
- Limits: TIA-568.3-E, plus anything stricter from the warranty program. Get it in writing.
- Reference method: 1 jumper, recorded in every result.
- Tiers: Tier 1 on everything; Tier 2 on the backbone. Will the backbone splices need bidirectional results? (Yes: use SmartLoop.)
- Deliverables: reports, inspection images, the warranty program's format and deadline.
Knowledge Check 1
Before testing starts on this project, what's the most important document to confirm?
Attempts: 0/2
Section 2: Planning & Setup
Budgets to expect
Horizontal (75 m typical OM4, 2 connections), 850 nm:
0.075 × 3.0 + 2 × 0.75 = 1.725 dB budget
Backbone (1.2 km OS2 outside plant, 2 connections, 2 splices), 1310/1550 nm:
1.2 × 0.5 + 2 × 0.75 + 2 × 0.3 = 2.70 dB budget
The CertiFiber Pro calculates these from the limit plus the connection and splice counts in each test setup, so enter the counts correctly.
Setup checklist
| Item | Action |
|---|---|
| LinkWare Live project | Three test setups (OM4 Tier 1, MPO, OS2 Tier 1 + Tier 2) and cable ID sets that match the labeling plan; status Active; sync the testers |
| Calibration | CertiFiber Pro, OptiFiber Pro, and MultiFiber Pro all within calibration (LinkWare Live warns 60 days ahead) |
| Firmware | Current on all Versiv units |
| Cords | Fluke EF-TRCs (OM4); singlemode TRCs with APC where the panels are APC; MPO test cords with the right pin genders; launch and tail cords for the OptiFiber Pro (160 m singlemode) |
| Inspection and cleaning | FI-7000 with LC, APC, and MPO tips; one-click LC and MPO cleaners; solvent and wipes |
| Safety | Safety glasses, a shard container, IPA handling, and laser safety for any live systems |
Knowledge Check 2
What is the TIA-568.3 budget for each backbone fiber (1.2 km OS2 outside plant, 2 connections, 2 splices)?
Attempts: 0/2
Section 3: Tier 1: Horizontal & Data-Center Links
OM4 horizontal: CertiFiber Pro
- Warm up the sources, then SET REF › RUN WIZARD with the 1-jumper method and EF-TRCs.
- Run TRC Verification: the target is better than 0.15 dB, and RE-VERIFY within ±0.02 dB.
- For each link: inspect, clean, and re-inspect both ends (save the images), then TEST in Smart Remote mode. That's two fibers at 850/1300 nm in about 3 seconds. Save it to the next cable ID.
- Re-verify the TRCs about every 500 tests, and whenever results drift.
MPO trunks: MultiFiber Pro
- Inspect and clean with the FI-7000 MPO tip and an MPO one-click cleaner, including the tester ports.
- Set the loss limit from the specification, and reference (polarity-agnostic referencing).
- Scan All on each trunk: 12 fibers in about 6 seconds. Check every position passes and that the polarity reads Method B.
- Save to the trunk's cable ID and download to LinkWare PC.
Knowledge Check 3
A data-center MPO trunk passes Scan All. What else must you confirm before saving it as good?
Attempts: 0/2
Section 4: Tier 2: The Campus Backbone
Tier 1 first
Certify each backbone fiber pair with the CertiFiber Pro singlemode sources at 1310 and 1550 nm, with a 1-jumper reference and APC test cords to match the panels, against the 2.70 dB budget.
Then Tier 2 with the OptiFiber Pro
- Connect the 160 m singlemode launch cord, the link, and a tail cord. Inspect every APC end-face with the APC tip.
- Use SmartLoop to loop fiber pairs at Building B, so each test gives bidirectional averages for both fibers.
- Test at 1310 and 1550 nm. Check each event: splices ≤ 0.3 dB and connections ≤ 0.75 dB (or the specification's tighter values), and reflectance at the APC connectors within the project's limit.
- Compare 1310 vs. 1550 nm event loss for hidden bends at the building entrances and splice cases.
- Save the traces and event tables under the same cable IDs as the Tier 1 results.
Edit carefully: If EventMap misreads an APC connector as a splice, correct the event type, and note why in the record.
Knowledge Check 4
Why use SmartLoop on the campus backbone?
Attempts: 0/2
Section 5: Handling Failures
Some links fail. Here's how a professional handles the typical ones on this job:
| Situation | Right response |
|---|---|
| OM4 link fails at 850 and 1300 nm by a similar amount | Inspect and clean both ends, re-test; if it still fails, OTDR it to find the bad connection, then re-terminate |
| Several links in a row read negative loss | Stop. The reference is bad: clean, re-reference, run TRC Verification, then re-test those links. |
| MPO trunk passes loss but polarity reads Method A | Wrong trunk or cassette type for a Method B design; replace the component and re-test |
| Backbone splice shows a gainer from one end | Look at the SmartLoop bidirectional average; if it's within limits, the splice is fine |
| Backbone fails at 1550 nm only | OTDR shows a bend-type event; relieve the bend at that distance, then re-test Tier 1 and Tier 2 |
| The warranty program wants a stricter limit than TIA | Test to the stricter limit. It was in the written specification you checked at the start. |
⚠️ Never adjust settings to pass a link. Changing the reference method, limit, or connection count to turn a FAIL into a PASS is falsifying the certification. Fix the link, or document and escalate it.
Knowledge Check 5
Several consecutive OM4 links read negative loss. What do you do?
Attempts: 0/2
Section 6: Close-Out & Handover
- Review in LinkWare PC: every cable ID present, no wrong-limit results, before and after results kept for repaired links.
- Reports: a Summary PDF and full graphical PDFs (Tier 1, Tier 2 traces, and inspection images) with the company logo.
- Record details: limit, reference method, connection/splice counts, tester serial numbers, and calibration dates on every result.
- Archive: the LinkWare project file plus the PDFs, filed with the job.
- Warranty: submit in the manufacturer's required format before their deadline.
- Handover: walk the customer through the summary and how to read the reports.
Series complete: You've gone from how light travels in glass to certifying and documenting a multi-building fiber project with the CertiFiber Pro, OptiFiber Pro, MultiFiber Pro, and FI-7000. Keep practicing on real jobs with a senior technician signing off your first projects.

8. The warranty program's limit is stricter than TIA-568.3-E. Which do you test to?
