Fluke Networks CFP-SM-ADD

The Fluke Networks CFP-SM-ADD is the CertiFiber Pro singlemode modules add-on kit for the Versiv cabling certification platform. It enables Tier 1 singlemode fiber certification by measuring optical loss and length so you can prove compliance to project limits and deliver acceptance documentation. It is commonly rented for new singlemode installs, datacenter cross-connect work, campus backbones, and any closeout package that requires standards-based loss testing with professional reporting.

Tier 1 certification uses an optical loss test set to validate end-to-end link performance. CertiFiber Pro measures insertion loss at the required wavelengths, verifies length, and produces pass or fail results against the selected limit. Because it is part of the Versiv system, it also supports consistent naming and job tracking so large projects can be certified without losing track of which links are complete and which need rework.

The singlemode source uses Fabry-Perot laser diodes at 1310 nm and 1550 nm. The power meter supports 850 nm, 1300 nm, 1310 nm, and 1550 nm and uses an InGaAs detector. Maximum length measurement for singlemode is listed at 130 km, with length measurement accuracy of plus or minus 1.5 m plus plus or minus 1 percent of length. Nominal singlemode output power is specified at greater than or equal to minus 4 dBm.

Accurate loss testing depends on setting a clean, correct reference and using the right reference method for the standard or customer requirement. CertiFiber Pro guides technicians through setting a reference so the power meter and source align to the chosen method, and it stores the setup with the project. Use quality test reference cords that match your connector type and keep them clean. Worn or contaminated cords can cause unstable readings and false failures, especially on low loss links.

CertiFiber Pro is designed to reduce mistakes in the field. ProjX lets you load project settings, limits, and naming ahead of time, then track completion as the team tests. The Taptive touchscreen interface simplifies setup so newer technicians can test consistently. LinkWare PC produces customer-ready reports and consolidates results. With LinkWare Live, teams can manage projects across sites and keep results centralized for review and export.

The power meter module lists a re-calibration period of 1 year. If you work under a quality program that requires traceable calibration, keep the current certificate with the job records. Even with valid calibration, daily best practice is to set a fresh reference for each project or when switching cord sets, and to inspect and clean connectors to avoid drift caused by contamination.

The CertiFiber Pro singlemode module tests at 1310 nm and 1550 nm using Fabry-Perot laser diode sources, which are the standard wavelengths for singlemode fiber certification per ANSI/TIA and ISO/IEC standards. The singlemode module delivers output power of at least -4 dBm with power measurement uncertainty less than plus or minus 5% plus or minus 32 pW, and measurement linearity within plus or minus 0.1 dB. It is fully compliant with TIA-526-14-B and IEC 61280-4-1 Encircled Flux launch condition requirements with no additional equipment or procedures needed.

Inspect and clean both ends of the link and your reference cords, then re-set the reference using the same cord set you will use to test. Confirm the selected limit matches the application and connector count, and verify the correct wavelengths are being tested. If loss remains high, isolate by swapping one cord at a time to rule out a bad jumper, then check for tight bends, damaged cable, or poor terminations. If you need event-level location of a fault, add an OTDR module such as OptiFiber Pro for Tier 2 analysis.
